                                     PART I
 
ITEM 1.  BUSINESS
 
GENERAL
 
     Illinois Tool Works Inc. (the "Company") was founded in 1912 and
incorporated in 1915. The Company manufactures and markets a variety of products
and systems that provide specific, problem-solving solutions for a diverse
customer base worldwide. The Company has more than 365 operations in 34
countries. The Company's business units are divided into three segments:
Engineered Components, Industrial Systems and Consumables, and Leasing and
Investments. Products in the Company's Engineered Components Segment include
short lead-time components and fasteners primarily for automotive, construction
and general industrial applications. This segment also manufactures specialty
products such as adhesives and static-control equipment. Industrial Systems and
Consumables products include longer lead-time machinery and related consumables
primarily for food and beverage, construction, automotive and general industrial
markets. They also manufacture specialty products for applications such as
industrial spray coating and quality measurement. The Leasing and Investment
segment makes investments that utilize the Company's cash flow, including
mortgage-related investments, leveraged and direct financing leases of
equipment, investments in properties and property developments, and affordable
housing investments.
 
     In the first quarter of 1993, the Company acquired the Miller Group
Ltd.("Miller"), a manufacturer of arc welding equipment, through an exchange of
ITW voting Common Stock for all of the voting Common Stock of Miller. In early
1996, the Company acquired all of the voting stock of Hobart Brothers Company
("Hobart"), a manufacturer of welding products, in exchange for shares of ITW
voting common stock. As a result, the Miller and Hobart acquisitions have been
accounted for as poolings of interests in conformity with Generally Accepted
Accounting Principles, specifically paragraphs 46 through 48 of Accounting
Principles Board Opinion ("APB") No. 16. Accordingly, the results of operations
for Miller and Hobart have been included in the Statement of Income as of the
beginning of 1993 and 1996, respectively. The impact of Miller and Hobart on
consolidated operating revenues, net income and net income per share was not
significant. Therefore, the 1992 and 1995 financial statements have not been
restated to reflect the acquisitions of Miller and Hobart, respectively.
 
     In late 1996, the Company acquired all of the outstanding common stock of
Azon Limited ("Azon"), an Australian manufacturer of strapping and other
industrial products. The acquisition has been accounted for as a purchase, and
accordingly, the acquired net assets have been recorded at their estimated fair
values at the date of acquisition. The results of operations have been included
in the Statement of Income from the acquisition date, except for the Azon
businesses which were expected to be sold, which were not consolidated at
December 31, 1996. During 1997, the Company disposed of the majority of the Azon
businesses which were expected to be sold. Based on the assumption that the Azon
acquisition had occurred on January 1, 1996 or January 1, 1995, the Company's
pro forma operating revenues, net income and net income per share would not have
been significantly different.
 
     During the five-year period ending December 31, 1997, the Company acquired
and disposed of numerous other operations which did not materially impact
consolidated results.

     Operating results of the segments are described on pages 18 through 20 and
26 of the Company's 1997 Annual Report to Stockholders.
 
BACKLOG
 
     Backlog generally is not considered a significant factor in the Company's
businesses as relatively short delivery periods and rapid inventory turnover are
characteristic of many of its products.
 
     Backlog by manufacturing segment as of December 31, 1997 and 1996 is
summarized as follows:
 


                                                                   BACKLOG IN

1996.................................................   $238,000     $221,000     $459,000

 
     Backlog orders scheduled for shipment beyond calendar year 1998 were not
material in either manufacturing segment as of December 31, 1997.

     The information set forth below is equally applicable to all industry
segments of the Company unless otherwise noted.
 
COMPETITION
 
     The Company's global competitive environment is complex because of the wide
diversity of products the Company manufactures and the markets it serves.
Depending on the product or market, the Company may compete with a few other
companies or with many others, some of which may be the Company's own licensees.
 
     The Company is a leading producer of plastic and metal components,
fasteners and assemblies; industrial fluids and adhesives; tooling for specialty
applications; welding products; packaging systems and related consumables;
industrial spray coating and static control equipment and systems; and quality
assurance equipment and systems.
 
RAW MATERIALS
 
     The Company uses raw materials of various types, primarily metals and
plastics that are available from numerous commercial sources. The availability
of materials and energy has not resulted in any business interruptions or other
major problems, nor are any such problems anticipated.
 
RESEARCH AND DEVELOPMENT
 
     The Company's growth has resulted from developing new and improved
products, broadening the application of established products, continuing efforts
to improve and develop new methods, processes and equipment, and from
acquisitions. Many new products are designed to reduce customers' costs by
eliminating steps in their manufacturing processes, reducing the number of parts
in an assembly, or by improving the quality of customers' assembled products.
Typically, the development of such products is accomplished by working closely
with customers on specific applications. Identifiable research and development
costs are set forth on page 27 of the Company's 1997 Annual Report to
Stockholders. Research and development expenditures in 1997 in local currencies
were consistent with 1996, however U.S. dollar expenditures decreased in 1997 as
a result of the negative impact of foreign currencies against the U.S. dollar.
 
     The Company owns approximately 1,770 unexpired United States patents
covering articles, methods and machines. Many counterparts of these patents have
also been obtained in various foreign countries. In addition, the Company has
approximately 333 applications for patents pending in the United States Patent
Office, but there is no assurance that any patent will be issued. The Company
maintains an active patent department for the administration of patents and
processing of patent applications.
 
     The Company believes that many of its patents are valuable and important.
Nevertheless, the Company credits its leadership in the markets it serves to
engineering capability; manufacturing techniques, skills and efficiency;
marketing and sales promotion; and service and delivery of quality products to
its customers.
 
TRADEMARKS
 
     Many of the Company's products are sold under various trademarks owned or
licensed by the Company. Among the most significant are: ITW, Apex, Buildex,
Deltar, Devcon, DeVilbiss, Fastex, Hi-Cone, Hobart, Keps, Magnaflux, Miller,
Minigrip, Newtec, Oxo, Paktron, Paslode, Powcon, Ramset, Ransburg, Red Head,
Shakeproof, Signode, Teks, Tenax and Zip-Pak.
 
ENVIRONMENTAL
 
     The Company believes that its plants and equipment are in substantial
compliance with applicable environmental regulations. Additional measures to
maintain compliance are not expected to materially affect the Company's capital
expenditures, competitive position, financial position or results of operations.
 
                                        3
   5
 
     Various legislative and administrative regulations concerning environmental
issues have become effective or are under consideration in many parts of the
world relating to manufacturing processes, and the sale or use of certain
products. To date, such developments have not had a substantial adverse impact
on the Company's sales or earnings. The Company has made considerable efforts to
develop and sell environmentally compatible products resulting in new and
expanding marketing opportunities.
 
EMPLOYEES
 
     The Company employed approximately 25,700 persons as of December 31, 1997
and considers its employee relations to be excellent.
 
INTERNATIONAL
 
     The Company's international operations include subsidiaries, joint ventures
and licensees in 34 countries on six continents. These operations serve such
markets as automotive, food and beverage, construction, general industrial,
industrial capital goods and others on a worldwide basis. The Company's
international subsidiaries contributed approximately 36% of operating revenues
in 1997 and 1996.
 
     Refer to pages 18 through 22 in the Company's 1997 Annual Report to
Stockholders for additional information on international activities.
International operations are subject to certain risks inherent in conducting
business in foreign countries, including price controls, exchange controls,
limitations on participation in local enterprises, nationalization,
expropriation and other governmental action, and changes in currency exchange
rates.
