                                 PROXY STATEMENT

SOLICITATION AND VOTING OF PROXIES

      The accompanying proxy is solicited on behalf of the Board of Directors of
Simpson Manufacturing Co., Inc., a Delaware corporation (the "Company"), for use
at the Annual Meeting of Stockholders of the Company to be held at the Company's
home office located at 4120 Dublin Blvd., Suite 400, Dublin, California, on May
18, 2000, at 2:00 p.m., Pacific Daylight Time, or any adjournment (the
"Meeting"). Only holders of record of the Company's Common Stock at the close of
business on March 19, 2001, will be entitled to vote at the Meeting. At the
close of business on that date, the Company had 12,083,112 shares of Common
Stock outstanding and entitled to vote. A majority, or 6,041,557, of these
shares, present in person or by proxy at the Meeting, will constitute a quorum
for the transaction of business. This Proxy Statement and the Company's Annual
Report to Stockholders for the year ended December 31, 2000, are being mailed to
each stockholder on or about April 16, 2001.


REVOCABILITY OF PROXY

      A stockholder who has given a proxy may revoke it at any time before it is
exercised at the Meeting, by (1) delivering to the Secretary of the Company (by
any means, including facsimile) a written notice stating that the proxy is
revoked, (2) signing and so delivering a proxy bearing a later date or (3)
attending the Meeting and voting in person (although attendance at the Meeting
will not, by itself, revoke a proxy). If, however, a stockholder's shares are
held of record by a broker, bank or other nominee and that stockholder wishes to
vote at the Meeting, the stockholder must bring to the Meeting a letter from the
broker, bank or other nominee confirming the stockholder's beneficial ownership
of the shares to be voted.


EXPENSES OF PROXY SOLICITATION

      The expenses of this solicitation of proxies will be paid by the Company.
Following the original mailing of this Proxy Statement and other soliciting
materials, the Company or its agents may also solicit proxies by mail, telephone
or facsimile or in person.


VOTING RIGHTS

      The holders of the Company's Common Stock are entitled to one vote per
share on any matter submitted to a vote of the stockholders, except that,
subject to certain conditions, stockholders may cumulate their votes in the
election of directors, and each stockholder may give one candidate a number of
votes equal to the number of directors to be elected multiplied by the number of
shares held by such stockholder or may distribute such stockholder's votes on
the same principle among as many candidates as such stockholder thinks fit. No
stockholder will be entitled, however, to cumulate votes (that is, cast for any
nominee a number of votes greater than the number of votes that the stockholder
normally is entitled to cast) unless the nominees' names have been placed in
nomination prior to the voting and the stockholder gives notice at the Meeting
prior to the voting of the stockholder's intention to cumulate the stockholder's
votes. If any one stockholder gives such notice, all stockholders may cumulate
their votes for nominees. In the election of directors, the nominees receiving
the highest number of affirmative votes of the shares entitled to be voted for
them up to the number of directors to be elected by such shares are elected.
Votes against a nominee and votes withheld have no legal effect.

                                       1

      The Board of Directors expects all nominees named below to be available
for election. In case any nominee is not available, the proxy holders may vote
for a substitute. The Company knows of no specific matter to be brought before
the Meeting that is not identified in the notice of the Meeting or this Proxy
Statement. If, however, proposals of stockholders that are not included in this
Proxy Statement are presented at the Meeting, the proxies will be voted in the
discretion of the proxy holders. Regulations of the Securities and Exchange
Commission permit the proxies solicited by this Proxy Statement to confer
discretionary authority with respect to matters of which the Company is not
aware a reasonable time before the Meeting. Accordingly, the proxy holders may
use their discretionary authority to vote with respect to any such matter
pursuant to the proxies solicited hereby.

      Directors will be elected at the Meeting by a plurality of the votes cast
at the Meeting by the holders of shares represented in person or by proxy.
Approval of Proposal No. 2 will require the affirmative vote of a majority of
the votes cast at the Meeting by the holders of shares represented in person or
by proxy. Abstentions and broker nonvotes are counted as shares present for
determination of a quorum but are not counted as affirmative or negative votes
on any item to be voted upon and are not counted in determining the number of
shares voted on any item.

      authority to dispose of or to vote shares that are under its management.

      shares. Neuberger does not, however, have any economic interest in the
      shares. The clients are the actual owners of the shares and have the sole
      right to receive and the power to direct the receipt of dividends from or
      proceeds from the sale of such shares. Neuberger Berman Inc. owns 100% of

      with respect to 357,200 shares. With regard to the shared voting power,

      beneficial owners for purpose of section 13(d) of the Securities and
      Exchange Act of 1934, as amended, since they have shared power to make
      decisions whether to retain or dispose of the securities. Neuberger is the
      sub-advisor to the Neuberger Funds. The above-mentioned shares are also
      included with the shared power to dispose calculation.

- ----------
(1)   In January 2001, the Company exercised its option to purchase the property
      leased from SIC. The transaction is expected to close in May 2001.
(2)   In January 2001, the Doolittle Investors lease was extended through
      December 31, 2009.

      The leases with the Partnerships are expected to continue until the
expiration of the respective terms of the leases, and they may hereafter be
renewed. The Company's future rent obligations under the continuing leases are
expected to be consistent with the rents paid in 2000, subject to adjustments as
provided in certain of the leases.

      If and when any lease is proposed to be amended or renewed or any property
subject to any lease is proposed to be purchased by the Company, the Company
will enter into such transaction only with the approval of a majority of the
directors of the Company who are not employees or officers of the Company and
who are not partners of any of the Partnerships and only after such directors
satisfy themselves that such transaction will be fair, just and reasonable as to
the Company, beneficial to the Company and on terms reasonably consistent with
the terms available from unrelated parties in similar transactions negotiated at
arm's length.

      The Company does not intend in the future to lease from any of the
Partnerships or any other entities controlled by any of its directors, officers
or employees any facilities that are not on or adjacent to the property subject
to the existing leases.

Cash Profit Sharing Bonus Plan

      The Company maintains a cash profit sharing bonus plan for the benefit of
employees of the Company and its subsidiaries. The Company may change, amend or
terminate its bonus plan at any time. Under the bonus plan as currently in
effect, the Compensation Committee of the Board of Directors determines a
"qualifying level" for the coming fiscal year for the Company, SDV and each
branch of SST. The qualifying level is equal to the value of the net operating
assets (as defined) of the Company, SDV or the respective branch of SST,
multiplied by a rate of return on those assets. If profits exceed the qualifying
level in any fiscal quarter, a portion of such excess profits is distributed to
the eligible employees as cash bonuses. The percentage of excess profits
distributed and the rates used to calculate the amounts to be distributed to the
Named Executive Officers are determined by the Compensation Committee of the
Board of Directors, while the percentage of excess profits distributed and the
rates used to calculate the amounts to be distributed to all other participants
are determined by the executive officers. The failure to earn a cash bonus in
any given quarter does not affect the ability to earn a cash bonus in any other
quarter. Amounts paid under these programs aggregated $18.6 million, $17.8
million and $14.6 million in 2000, 1999 and 1998, respectively, the amounts of
which paid to Named Executive Officers in 2000, 1999 and 1998 are shown in the
Summary Compensation Table above.

1994 Stock Option Plan

      By affording selected employees and directors of and consultants to the
Company and its subsidiaries the opportunity to buy shares of Common Stock of
the Company, the Simpson Manufacturing Co., Inc. 1994 Stock Option Plan (the
"Option Plan") is intended to enhance the ability of the Company and its
subsidiaries to retain the services of persons who are now employees, directors
or consultants, to secure and retain the services of new employees, directors
and consultants, and to provide incentives for such persons to exert maximum
efforts for the success of the Company and its subsidiaries. The Option Plan was
adopted by the Company's Board of Directors and approved by the Company's
stockholders prior to the Company's initial public offering in 1994. It was
amended in 1997 and again in 2000 with shareholder approval. No more than
2,000,000 shares of Common Stock may be sold (including shares already sold)
pursuant to all options granted under the Option Plan. Common Stock sold on
exercise of options granted under the Option Plan may be previously unissued
shares or reacquired shares, bought on the market or otherwise. Options to
purchase 139,750 and 117,250 shares of Common Stock were granted pursuant to
commitments made related to the preceding fiscal years under the Option Plan in
1999 and 1998, respectively, and options to purchase 7,000 shares of Common
Stock, out of a possible 178,500 shares, were committed to be granted in 2000.
No options were committed to be granted under the Option Plan to Named Executive
Officers in 2000. Options granted under the Option Plan to Named Executive
Officers in 1999 and 1998 are shown in the Summary Compensation Table above.


Profit Sharing Plans

      The Company's subsidiaries maintain defined contribution profit sharing
plans for their U.S. based salaried employees (the "Salaried Plan") and for U.S.
based nonunion hourly employees (the "Hourly Plan"). An employee is eligible for
participation in a given year if he or she is an employee on the first and last
days of that calendar year and completes at least 1,000 hours of service during
that calendar year for the Salaried Plan or 750 hours of service during that
calendar year for the Hourly Plan. As of December 31, 2000, there were 349
employees participating in the Salaried Plan and 508 employees participating in
the Hourly Plan. Under the Salaried Plan and the Hourly Plan, the Board of
Directors may authorize contributions to the plan trusts in their exclusive
discretion. Contributions to the plan trusts by the Company's subsidiaries are
limited to the amount deductible for federal income tax purposes under section
404(a) of the Internal Revenue Code. Barclay Simpson and Michael J. Herbert, who
are Named Executive Officers of the Company, are trustees of the plan trusts.
Barclay Simpson is also a participant in the Salaried Plan. The amounts
contributed by the Company for his account in 2000, 1999 and 1998 is shown in
the Summary Compensation Table above. Certain of the Company's foreign
subsidiaries maintain similar plans for their employees.


Compensation of Directors

      The Company's directors who do not receive compensation as officers or
employees of the Company are each paid an annual retainer of $10,000 and a fee

1995 Independent Director Stock Option Plan

      The Simpson Manufacturing Co., Inc. 1995 Independent Director Stock Option
Plan (the "Independent Director Plan") was adopted by the Board of Directors and
approved by the stockholders in 1995 and was amended by the Board of Directors
in 1997. The purpose of the Independent Director Plan is to give independent
directors of the Company an opportunity to buy shares of Common Stock of the
Company, to encourage independent directors in their efforts on behalf of the
Company and to secure their continued service to the Company. No options to
purchase shares of Common Stock were committed to be granted under the
Independent Director Plan in 2000.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

      The Audit Committee of the Board of Directors (the "Audit Committee") is
responsible for financial and accounting management. Its policies and practices
are described as follows:

      COMPOSITION. The Audit Committee is composed of three independent
directors, as defined by the New York Stock Exchange rules, and operates under a
written charter adopted by the Board of Directors, a copy of which is attached
hereto as Exhibit A. The members of the Audit Committee are Barry Lawson
Williams, Chairman, Earl F. Cheit and Sunne Wright McPeak.

      RESPONSIBILITIES. The responsibilities of the Audit Committee include
recommending to the Board of Directors an accounting firm to be engaged as the
Company's independent accountants. Management is responsible for the Company's
internal controls and financial reporting process. The independent accountants
are responsible for performing an independent audit of the Company's
consolidated financial statements in accordance with generally accepted auditing
standards and for issuing a report theron. The Audit Committee's responsibility
is to oversee these processes.

      REVIEW WITH MANAGEMENT AND INDEPENDENT ACCOUNTANTS. The Audit Committee
has met and held discussions with management and the independent accountants.
Management represented to the Audit Committee that the Company's consolidated
financial statements were prepared in accordance with generally accepted
accounting principles, and the Audit Committee has reviewed and discussed the
consolidated financial statements with management and the independent
accountants. The Audit Committee has discussed with the independent accountants
matters required to be discussed by Statement on Auditing Standards No. 61,
"Communication with Audit Committees."

      The Company's independent accountants also provided the Audit Committee
the written disclosures and the letter required by Independent Standards Board
Standard No. 1, "Independence Discussions with Audit Committees," and the Audit
Committee discussed with the independent accountants, PricewaterhouseCoopers
LLP, that firm's independence.

      SUMMARY. Based upon the Audit Committee's discussions with management and
the independent accountants and the Audit Committee's review of the
representations of management, and the report of the independent accountants to
the Audit Committee, the Audit Committee recommended that the Board of Directors
include the audited consolidated financial statements in the Company's Annual
Report on Form 10-K for the year ended December 31, 2000, as filed with the
Securities and Exchange Commission. The Audit Committee believes that it has
satisfied its responsibilities under its charter.

                                        Sunne Wright McPeak


AUDIT AND RELATED FEES

      AUDIT FEES. The aggregate fees billed by PricewaterhouseCoopers LLP for
professional services for the audit of Company's annual consolidated financial
statements for 2000 and the review of the consolidated financial statements
included in the Company's Forms 10-Q for 2000 were $186,000.

      FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES. There were
no fees billed by PricewaterhouseCoopers LLP to the Company for financial
information systems design and implementation fees for 2000.

                                       13
   17

      ALL OTHER FEES. The aggregate fees billed to the Company for all other
services rendered by PricewaterhouseCoopers LLP for 2000, including fees for
income tax preparation and consultation and for statutorily required reviews in
certain locations outside the U.S. where the Company has operations, were
$334,000.

      The Audit Committee has determined that the fees for services rendered
were compatible with maintaining PricewaterhouseCoopers LLP's independence.


REPORT OF THE COMPENSATION COMMITTEE, 1994 STOCK OPTION PLAN COMMITTEE AND BOARD
OF DIRECTORS ON EXECUTIVE COMPENSATION

      The Compensation Committee and the 1994 Stock Option Plan Committee of the
Board of Directors are responsible for the development and review of the
Company's compensation policy for all the salaried employees. The overall
philosophy of the Company's compensation program is to provide a high degree of
incentive to employees by creating programs that reward achievement of specific
profit goals. The Company believes that these incentive programs based on profit
targets are best suited to align the interests of employees and stockholders.
The Company does not have any special plans for the Chief Executive Officer or
other executive officers of the Company. The absence of special plans for the
executive officers is intended to create a sense of unity and cooperation among
the Company's employees. The four elements of the Company's compensation plan
for most salaried employees and all officers are base salary, a profit sharing
retirement plan, a cash profit sharing bonus plan and the Option Plan.

      The Compensation Committee has not performed any recent salary surveys,
but based on surveys in prior years and recent raises, it believes the base
salaries for the Chief Executive Officer and other executive officers are
competitive when compared to similar companies. Stephen B. Lamson, who was
promoted to President and Chief Operating Officer of Simpson Strong-Tie in 2000,
received an increase in salary of 53.9%. Thomas J Fitzmyers, President and Chief
Executive Officer, and Donald M. Townsend, President and Chief Executive Officer
of SDV, each received an increase in salary of 3% in 2000. Barclay Simpson,
Chairman, did not receive an increase in salary in 2000.

      All U.S. based salaried employees, including the Chief Executive Officer
and other executive officers, participate in the profit sharing plan in
proportion to their salaries. For 2000, 15% of all U.S. based salaried
employees' base pay will be contributed to the profit sharing plan subject to
the limitations of applicable law. In 2000, Thomas J Fitzmyers, President and
Chief Executive Officer, Stephen B. Lamson, President and Chief Operating
Officer of Simpson Strong-Tie and Donald M. Townsend, President and Chief
Executive Officer of SDV, were subject to a contribution limit under applicable
law; the Company's contribution to the profit sharing plan for their accounts
was $24,000 each.

      All salaried employees, except those on commission programs, participate
in the Company's quarterly cash profit sharing bonus plan. Annually, the
Compensation Committee establishes an acceptable range of participation in the
profits in excess of the qualifying level to be distributed as cash bonuses for
each profit center. The Compensation Committee also approves the specific
percentages to be distributed to the Chief Executive Officer and other executive
officers. The executive officers determine the specific percentages for
distributions to all other participating employees. Historically, the percentage
of profits in excess of the qualifying level distributed under these plans has
not changed substantially from year to year. Employees with higher levels of
responsibility typically receive higher proportions of the cash profit sharing
for their profit center. In 2000, the Chief Executive Officer received 514% of
his base salary in cash profit sharing bonuses. Because the cash profit sharing
bonus plan is based upon a return on net operating assets, and not subjectively
determined, the Compensation Committee believes the plan provides substantial
incentive to all participating employees, not only the Company's officers.

                                       14
   18

      The 1994 Stock Option Plan Committee believes an option plan is most
effective if options are granted to all participants on an objective rather than
subjective basis. Therefore, under the Option Plan, participants are granted
options if Company-wide and profit center operating goals are met. The
Compensation Committee establishes these goals at the beginning of the year. The
1994 Stock Option Plan Committee also believes that option plans with broad
based participation are most effective. The 1994 Stock Option Plan Committee
determines each year the employees who are eligible to participate in the Option
Plan, based on job responsibilities and contributions made to the Company. At
present, over one quarter of the Company's salaried employees participate in the
Option Plan. The 1994 Stock Option Plan Committee determines the number of
options to be granted under the Option Plan. In determining the potential
grants, the 1994 Stock Option Plan Committee considers previous stock and option
awards, current options owned, job responsibilities and contributions to the
Company. These same considerations apply to option grants to the Chief Executive
Officer and other executive officers. Because of the responsibilities of the
Chief Executive Officer and the other executive officers, their stock option
grants are generally higher than those of other participants who also achieve
their goals. Most of the operating goals were not met in 2000 and, accordingly,
options to purchase only 7,000 shares of Common Stock, out of a possible 178,500
shares, were committed to be granted in 2000.

      In 1995, the Company adopted the Independent Director Plan to give the
outside members of the Board of Directors an opportunity to buy shares of Common
Stock of the Company. The Independent Director Plan is administered by the Board
of Directors (as its manager and not as its trustee) and determines which
persons are eligible to be granted options. The Board of Directors believes this
kind of option plan is most effective if options are granted to outside
directors on an objective basis. Therefore, the Board of Directors determines
the number of shares subject to options that they believe will be an appropriate
incentive to be granted when an outside director becomes a member of the Board
of Directors and if Company-wide operating goals, established by the
Compensation Committee at the beginning of the year, are met. These operating
goals were not met in 2000 and, accordingly, no stock options were committed to
be granted to any of the outside directors.

            Company's accounting principles and underlying estimates, and a
            frank and open discussion of other significant decisions made by
            management in preparing the financial disclosure and reviewed by the

            the Committee a formal written statement delineating all
            relationships between the accountants and the Company. The Committee
            also shall engage in a dialogue with the accountants with respect to
