COMPX REPORTS FIRST QUARTER 2004 OPERATING RESULTS

Dallas,  TEXAS ...  April 29, 2004 ...  CompX  International  Inc.  (NYSE:  CIX)
announced  today sales of $53.1  million  for the first  quarter of 2004 and net
income of $1.6 million,  or $0.10 per diluted share. This represents an increase
in sales of 4% from $51.0 million in the prior year quarter.  For the comparable
2003 quarter, the Company reported net income of $600,000,  or $0.04 per diluted
share.

Certain items  affecting the  comparability  of CompX's first quarter results in
2003 and 2004 are discussed below.

o    Fluctuations  in currency  exchange rates  favorably  impacted net sales by
$2.5  million;  however  the impact on net income  was  insignificant.  The
impact on net sales is primarily  due to relative  changes in the US dollar
to euro and Canadian dollar exchange rates.
o    In the  first  quarter  of 2003,  the  consolidation  of the two  plants in
Kitchener,  Ontario  resulted in  $400,000 of expenses  included in cost of
goods sold ($0.02 per diluted share, net of income tax benefit).

"As we expected,  our cost reduction activities are having a favorable impact as
indicated by the marked improvement in our operating  results,"  commented David
A. Bowers,  President & CEO.  "Additionally,  2004's positive beginning reflects
diligent  efforts  to  eliminate  unprofitable  business  in our slide  segments
through value  engineering,  price  increases,  moving  production to lower cost
facilities and targeted improvement in manufacturing processes."

Security Products Segment
The CompX Security  Products segment  experienced a 2%
increase in net sales to $18.8 million and a 5% increase in operating  income to
$2.3 million in the first  quarter of 2004 over the same quarter last year.  The
improvement in operating  income  resulted from a more favorable  product mix as
well as the  benefit of cost  reduction  efforts.  Performance  in this  segment
continues  to be a strong  contributor  with  operating  income  of 12.5% of net
sales,  due in part to the broad scope of markets  served with our various  lock
products.

Waterloo  Segment
Net sales for the Waterloo  segment  increased 4% to $24.7  million in the first
quarter of 2004 from $23.8 million in the first quarter in 2003. The increase is
primarily  attributable to  fluctuations  in currency  exchange rates as well as
increases in certain slide product prices. Operating income for this segment was
$350,000 in the first  quarter of 2004 as compared to $450,000 in the prior year
quarter.  Operating  income  comparison  to the prior year for this  segment was
affected by price  increases,  by unfavorable  2004 relative changes in currency
exchange rates of $700,000 and the previously mentioned 2003 plant consolidation
costs of $400,000.

Thomas Regout
Segment Net sales for the Thomas Regout segment  increased 9% to $9.6 million in
the first  quarter of 2004 from $8.8 million in the first  quarter of 2003.  The
increase is due to relative changes in currency exchange rates,  which favorably
impacted  net  sales by $1.4  million,  offset  in part by the  effect  of lower
volumes of precision slide shipments to European office furniture manufacturers.
The first  quarter of 2004  operating  income  for this  segment  was  breakeven
compared to an operating loss of $900,000 in 2003. The  improvement in operating
income was primarily  from the cost reduction  benefits  achieved as a result of
the restructuring  activity initiated in 2003. The impact of relative changes in
currency exchange rates on operating income  comparisons was not significant for
this segment.

Mr. Bowers concluded, "Our first quarter results are an encouraging step forward
and  demonstrate  the benefits of the  initiatives  undertaken over the past two
years.  We expect to continue  those  efforts  while we focus on  releasing  new
products and developing  new, more profitable  markets with those  products.  In
addition,  we continue to evaluate strategic  alternatives for our Thomas Regout
operations, some of which could result in additional charges in the future."

Liquidity and Cash Flow
Cash provided by operating  activities  improved to $3.4 million for the quarter
compared to $1.5 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  quarter of 2004,  the Company
utilized a portion of its cash balance to reduce debt by $12.0 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 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.
