COMPX REPORTS HIGHER SALES AND PROFITS
FOR SECOND QUARTER 2004

Dallas,  TEXAS ...  July 27,  2004 ...  CompX  International  Inc.  (NYSE:  CIX)
announced  today sales of $56.7  million for the second  quarter of 2004 and net
income of $3.3 million,  or $0.22 per diluted share. This represents an increase
in sales of 14% from $49.7 million in the year ago quarter. The Company reported
net income of $300,000 for the  comparable  2003  quarter,  or $0.02 per diluted
share.  Net sales for the  six-month  period  ended  June 30,  2004 were  $109.9
million  compared to $100.7  million for same period of the previous  year.  Net
income for the six-month  period in 2004 was $4.8 million,  or $0.32 per diluted
share, compared to $900,000, or $0.06 per diluted share in 2003.

"We benefited  this quarter from higher  demand  across most product  segments,"
commented  David A. Bowers,  President & CEO. "This combined with the benefit of
an improved cost structure,  resulting from various  operating  initiatives over
the last two years, contributed to the improvement in operating income margins."

Security Products Segment
CompX  Security  Products  experienced  a 5% increase in net sales in the second
quarter of 2004 to $19.7 million compared to the same quarter last year of $18.8
million.  Net sales for this  segment  increased 3% on a  year-to-date  basis to
$38.4  million from $37.3  million in 2003  primarily,  as a result of increased
sales volumes.  Second quarter  operating  income increased from $2.5 million in
2003 to $2.8 million in 2004.  For the  year-to-date  period,  operating  income
improved to $5.1 million in 2004  compared to $4.7 million in 2003.  The quarter
and  year-to-date  operating  income  improvements  were  primarily  due  to the
increase in sales volumes which benefited from  manufacturing  efficiencies as a
result of earlier cost reductions.

Waterloo Segment
Net sales for the Waterloo segment  increased 16% to $26.5 million in the second
quarter of 2004 from $22.9  million in the second  quarter in 2003 and increased
10% for the  six-month  period  from $46.7  million in 2003 to $51.2  million in
2004.  The  increase is  primarily  related to higher  precision  slide  product
volumes at certain  customers,  increases  in certain  precision  slide  product
surcharges  and  prices,  primarily  to recover the  dramatic  rise in steel raw
material  prices  experienced  during  the year,  and the  strengthening  of the
Canadian dollar in 2004 in relation to the US dollar.  Operating income for this
segment was $2.4 million in the second  quarter of 2004 as compared to a loss of
$600,000 in the prior year quarter and  improved  from a loss of $100,000 in the
first six  months of 2003  compared  to income of $2.7  million in the first six
months of 2004.  Operating  income  improvements  are primarily  attributable to
improved  margins   resulting  from  a  lower  fixed  cost  structure  in  2004,
non-recurring expenses of approximately $800,000 in the first six months of 2003
($400,000  in the  second  quarter)  associated  with the  consolidation  of the
Company's two Canadian  facilities  and, to a lesser  extent,  product  pricing.
Relative  changes in currency  exchange rates negatively  impacted  year-to-date
operating  income  comparisons  by  approximately  $800,000  but did not  have a
significant impact on the second quarter results.

Thomas Regout Segment
Net sales for the Thomas  Regout  segment  increased 33% to $10.6 million in the
second  quarter of 2004 from $7.9 million in the second quarter of 2003. For the
six-month period,  net sales increased 21% to $20.2 million as compared to $16.8
million for 2003.  The  improvement in net sales is due to an increase in orders
from European customers and the strengthening of the euro in 2004 in relation to
the US dollar.  The second quarter of 2004 operating income for this segment was
$400,000  compared  to an  operating  loss of $1.0  million  in  2003.  The 2004
year-to-date operating income for this segment was $500,000,  compared to a loss
of $1.9 million for 2003. The  improvement in operating  income is primarily the
result of the  restructuring  actions taken in 2003 combined with an increase in
sales.  The impact of relative  changes in currency  exchange rates on operating
income comparisons was not significant for this segment.

Mr. Bowers  concluded,  "We are encouraged by the improved  demand and favorable
results of our cost control  initiatives.  The  commitment  and hard work of our
employees  over the past two years are a  significant  factor in the  success of
these  initiatives.  While  demand  continues  to be  good  across  all  product
segments, certain customers are seeking lower cost Asian sources as alternatives
to our  products.  Although  we  believe  the  impact of this will be  mitigated
through  our ongoing  initiatives  to expand  both new  products  and new market
opportunities,  the recent increase in order rates may be moderated to a certain
extent in the near term.  We continue to believe  the value  proposition  of our
collaborative  innovative design,  high quality products and responsive service,
upon which our partners  have come to depend,  will continue to be valued by our
customer base."

Liquidity and Cash Flow
Cash  provided by operating  activities  improved to $13.7  million for the 2004
six-month  period compared to $8.4 million in the prior year. The improvement in
cash provided by operating  activities was due to the improved operating results
and the efficient management of working capital.  During the first six months of
2004,  the  Company  utilized  a portion of its cash  balance to reduce  debt by
approximately $24.0 million.

CompX is a leading  manufacturer  of  precision  ball bearing  slides,  security
products and ergonomic computer support systems.

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  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  forecasted 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.
