                          COMPX REPORTS SALES, PROFITS
                             FOR SECOND QUARTER 2005

Dallas,  TEXAS ...  August 2, 2005 ...  CompX  International  Inc.  (NYSE:  CIX)
announced today sales of $45.7 million for the second quarter of 2005,  compared
to $46.2  million  in the  second  quarter  of 2004.  Operating  income was $4.7
million in the second  quarter of 2005  compared  to $4.8  million in the second
quarter of 2004.  Income from  continuing  operations  for the second quarter of
2005 was $2.4 million, or $0.16 per diluted share,  compared to $3.0 million, or
$0.20 per diluted share, in the second quarter of 2004.

Net sales for the  six-month  period  ended  June 30,  2005  increased  to $92.6
million  from $89.8  million for same period of the previous  year.  Income from
continuing  operations  for the six-month  period in 2005 was $4.6  million,  or
$0.30 per diluted share, compared to $4.5 million, or $0.30 per diluted share in
2004. Sales and operating income comparisons were impacted by the net effects of
higher selling prices for certain  products  across all segments and lower sales
volumes  for  certain  products.  Due to certain  limitations  on the ability to
utilize foreign tax credits,  the Company's effective income tax rate was higher
in the first six months of 2005 as compared to the same period of 2004.

"While we continue to see economic  recovery  progressing in the majority of the
markets we serve,  competition from low priced Asian based manufacturers remains
a challenge," commented David A. Bowers,  President & CEO. "Our ongoing focus on
strengthening  our  sales  process  as  well  as  cost  control  and  production
efficiency  efforts is expected to continue to support our  profitability  as we
explore lower  manufacturing  cost alternatives to address the high volume,  low
price segment of the business."

Mr. Bowers  concluded,  "Management's  effort to identify new  opportunities for
growth and  diversification  is progressing  with the completion of a relatively
small acquisition in August. Our significant cash position, as well as borrowing
availability  under  our  credit  agreement,  provides  the  liquidity  to  take
advantage of additional opportunities as they are identified."

CompX is a leading  manufacturer  of  precision  ball bearing  slides,  security
products  and  ergonomic  computer  support  systems.  It  operates  from  seven
locations in the U.S., Canada and Taiwan and employs more than 1,300 people.

Statements in this release relating to matters that are not historical facts are
forward-looking  statements based upon management's belief and assumptions using
currently  available  information.  Although  CompX  believes  the  expectations
reflected in such forward-looking  statements are reasonable, it cannot give any
assurances that these expectations will prove to be correct. Such statements, by
their  nature,   involve   substantial  risks  and   uncertainties   that  could
significantly  impact expected  results,  and actual future results could differ
materially from those described in such forward-looking statements.  While it is
not  possible to identify all  factors,  CompX  continues to face many risks and
uncertainties.  Among the factors  that could  cause  actual  future  results to
differ  materially  include,  but are  not  limited  to,  general  economic  and
political conditions,  demand for office furniture,  service industry employment
levels,  competitive  products  and prices,  fluctuations  in currency  exchange
rates, the introduction of trade barriers, potential difficulties in integrating
completed  acquisitions,  the  timing  and amount of future  cost  savings  from
restructuring  actions,  the  ability to sustain or  increase  operating  income
improvement  resulting from cost control initiatives,  uncertainties  associated
with new  product  development  and other  risks and  uncertainties  detailed in
CompX's Securities and Exchange Commission filings.  Should one or more of these
risks materialize (or the consequences of such a development  worsen), or should
the  underlying  assumptions  prove  incorrect,   actual  results  could  differ
materially  from those  forecast or expected.  CompX  disclaims any intention or
obligation to publicly update or revise such  statements  whether as a result of
new information, future events or otherwise.
