                    COMPX REPORTS FIRST QUARTER 2006 RESULTS

Dallas, TEXAS ... May 4, 2006 ... CompX International Inc. (NYSE: CIX) announced
today  sales of $47.0  million for the first  quarter of 2006  compared to $46.8
million in the same  period of 2005.  Operating  income was $4.8  million in the
first quarter of 2006  compared to $4.1 million in the same period of 2005.  Net
sales comparisons were positively  impacted by additional sales volume resulting
from the  acquisition of a small  components  business in August 2005 and volume
increases  within  security  products  which  were  partially  offset  by  sales
decreases in furniture  components.  Operating income comparisons were primarily
impacted by the small  acquisition  referred to above, a more favorable  product
mix and continued  benefit of cost improvement  initiatives.  Earnings per share
from  continuing  operations for the first quarter of 2006 was $0.16 compared to
$0.14 in the same period of 2005.

"Our ongoing efforts  focusing on replacing sales of low margin,  commodity type
products with sales of higher margin  feature-oriented  products  contributed to
our gross margin improvement from 22% in the first quarter of 2005 to 25% in the
first quarter of 2006,"  commented  David A. Bowers,  President & CEO. "While we
expect to experience continued competitive  challenges,  especially  considering
the volatility of increasing raw material costs, we will continue our efforts in
areas where we have been successful historically including improving operational
efficiencies and developing value-added solutions for our customers."

CompX is a leading  manufacturer of security products and furniture  components.
It operates from eight locations in the U.S., Canada and Taiwan and employs more
than 1,200 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.
