             Report of Independent Registered Public Accounting Firm



To the Participants and Administrative Committee of
 CompX Contributory Retirement Plan:

In our opinion, the accompanying statements of net assets available for benefits
and the  related  statement  of  changes in net assets  available  for  benefits
present fairly, in all material respects,  the net assets available for benefits
of the CompX Contributory  Retirement Plan (the "Plan") at December 31, 2003 and
2004,  and the changes in net assets  available  for benefits for the year ended
December 31, 2004 in conformity with accounting principles generally accepted in
the United States of America.  These financial statements are the responsibility
of the Plan's  management.  Our responsibility is to express an opinion on these
financial  statements  based on our  audits.  We  conducted  our audits of these
statements in accordance  with the  standards of the Public  Company  Accounting
Oversight  Board  (United  States).  Those  standards  require  that we plan and
perform the audit to obtain  reasonable  assurance  about  whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements,  assessing the accounting  principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

Our audits  were  conducted  for the  purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental Schedule of Assets (Held
at End of Year) is presented for the purpose of additional analysis and is not a
required part of the basic financial statements but is supplementary information
required by the  Department of Labor's Rules and  Regulations  for Reporting and
Disclosure  under the Employee  Retirement  Income  Security  Act of 1974.  This
supplemental  schedule  is the  responsibility  of the  Plan's  management.  The
supplemental  schedule has been subjected to the auditing  procedures applied in
the audits of the basic  financial  statements  and, in our  opinion,  is fairly
stated in all material  respects in relation to the basic  financial  statements
taken as a whole.

                       COMPX CONTRIBUTORY RETIREMENT PLAN

                          NOTES TO FINANCIAL STATEMENTS

Note 1 -  Description of Plan and significant accounting policies:


     General.  The following  description of the Compx  Contributory  Retirement
Plan (the "Plan") provides only general  information.  Participants should refer
to the Plan agreement for a more complete description of the Plan's provisions.

     The  Plan  is a  defined  contribution  plan  which  covers  eligible  U.S.
employees of CompX International Inc. and its U.S.  subsidiaries  (collectively,
the  "Employer").  Employees are eligible to  participate  in the Plan as of the
first entry date, as defined,  concurrent  with or next following the completion
of 90 days of  eligible  service  and  attaining  20 years  of age.  The Plan is
subject to the  provisions  of the Employee  Retirement  Income  Security Act of
1974, as amended ("ERISA").

     The Employer is 83% owned by CompX Group, a majority-owned subsidiary of NL
Industries,  Inc.  at  December  31,  2004.  NL owns 82.4% of CompX  Group,  and
Titanium Metals  Corporation  ("TIMET") owns the remaining 17.6% of CompX Group.
At December 31, 2004 (i) TIMET owns an  additional  2% of CompX  directly,  (ii)
Valhi, Inc. holds,  directly or through a subsidiary,  approximately 83% of NL's
outstanding  common stock and  approximately 41% of TIMET's  outstanding  common
stock and (iii) Contran  Corporation  holds,  directly or through  subsidiaries,
approximately  91% of Valhi's  outstanding  common stock.  Substantially  all of
Contran's outstanding voting stock is held by trusts established for the benefit
of certain children and grandchildren of Harold C. Simmons, of which Mr. Simmons
is sole trustee,  or is held by Mr. Simmons or persons or other entities related
to Mr. Simmons.  Consequently, Mr. Simmons may be deemed to control each of such
companies and the Employer.

     Contributions.  The Plan permits  participants to defer 1% to 100% of their
annual  compensation  as  pre-tax  contributions,  not to exceed a  deferral  of
$13,000  in 2004  (subject  to  adjustment  in future  years),  through  payroll
deductions. Participants who will be at least age 50 by the end of the Plan year
may elect to make "catch-up" contributions, not to exceed an additional deferral
of $3,000 in 2004  (subject to  adjustments  in future  years)  through  payroll
deductions.   Pursuant  to  the  Internal   Revenue  Code,   total   participant
contributions  (pre-tax and after-tax) and employer contributions are limited to
an aggregate of $41,000 from all employer  defined  contribution  plans in 2004.
The  Employer's  contribution  is based upon a  profit-sharing  formula  and the
Employer's profit, as defined, during the Plan year. The Employer's contribution
is  allocated  to  participants'  accounts on a  percentage  or  matching  basis
relative to the participants'  contributions  (excluding catch-up contributions)
for the year. The Employer's  contribution is reduced,  as provided by the Plan,
by nonvested  amounts  forfeited by participants  who withdraw from the Plan. At
December  31,  2003 and 2004,  unallocated  forfeited  nonvested  accounts  were
$73,250 and $103,175  respectively.  Forfeitures  of $17,642 were used to reduce
employer contributions for the year ended December 31, 2004.

     Vesting and benefits.  Salary deferrals  (including  earnings  thereon) are
immediately  vested while Employer  contributions  (including  earnings thereon)
vest at the rate of 20% per year of service, as defined.

     Upon  termination  of employment,  retirement or death,  a participant  (or
beneficiary,  if  applicable)  may elect to receive either (i) a lump sum amount
equal to the vested  value of the  participant's  accounts or (ii)  installments
over a period of not more than 30 years. Distribution of a participant's account
balance  in a lump sum  without  the  participant's  consent  may be made if the
vested  portion of the  participant's  account  is not  greater  than  $5,000 or
distribution  commences after the participant attains 65 years. With the consent
of the Plan  administrators,  participants  can borrow amounts from their vested
account balances, subject to certain limitations under the Plan.

     Benefits are recorded when paid.

     Participants'  accounts.  Participants can direct the Plan administrator to
invest, in 1% increments,  their account balance in  publicly-traded  registered
investment  companies or commingled trusts administered by Putnam Investments or
in  CompX  International  Inc.  common  stock  (not  to  exceed  25% of  account
balances).  Below are the investment  fund options  available to participants at
December 31, 2004:

     The fund descriptions provide only general information. Participants should
refer to the Prospectus of each fund for a more complete description.

     Each participant's account is credited with the participant's  contribution
and an allocation of the Employer's  contribution and Plan earnings, and charged
with  an  allocation  of  administrative  expenses.  Allocations  are  based  on
participant earnings, matching or account balances, as defined in the Plan.

     In addition to the investment fund options,  a "Loan Fund" is maintained to
account for loans to  participants,  as permitted by the Plan. A participant  is
able to borrow from  his/her  fund  account an amount  ranging from a minimum of
$1,000 up to a maximum that is  generally  equal to the lesser of $50,000 or 50%
of his/her vested account balance.  A loan is  collateralized  by the balance in
the  participant's  account and bears interest at rates  commensurate with local
prevailing rates. For outstanding loans at December 31, 2004, the interest rates
ranged from 5.0% to 10.5% and mature through 2019.

     Plan termination.  The Employer has the right under the Plan to discontinue
its  contributions at any time and to terminate the Plan, in compliance with the
provisions of ERISA.  In the event the Plan is  terminated,  the accounts of all
participants will become fully vested.

     Basis of accounting.  The financial  statements of the Plan are prepared in
accordance with accounting principles generally accepted in the United States of
America. Valuation of investments is more fully described in Note 2.

     Management estimates. The preparation of financial statements in conformity
with accounting  principles  generally  accepted in the United States of America
requires  management to make estimates and assumptions  that affect the reported
amounts  of  assets,  liabilities,   and  changes  therein,  and  disclosure  of
contingent assets and liabilities. Actual results may, in some instances, differ
from previously estimated amounts.

     Risks and  uncertainties.  The Plan provides for various investment options
in a variety of stocks, bonds, fixed income securities,  mutual funds, and other
investment securities.  Investment securities are exposed to various risks, such
as interest rate,  market, and credit risks. Due to the level of risk associated
with certain  investment  securities,  it is at least  reasonably  possible that
changes in the values of investment  securities  will occur in the near term and
that such changes could materially affect participants' account balances and the
amounts reported in the Plan's statement of net assets available for benefits.

     Expenses of  administering  the Plan.  The Plan  provides that the Employer
will generally reimburse the Plan for administrative  expenses paid by the Plan.
The Employer paid a significant portion of the 2004 administrative expenses.

     Tax status. The Plan has been notified by the Internal Revenue Service in a
letter dated  December 13, 2004 that it is a qualified plan under Section 401(a)
and Section 401(k) of the Internal  Revenue Code (the "Code"),  and is therefore
exempt from federal income taxes under provisions of Section 501(a) of the Code.

     The Plan has been amended since it was notified of its exempt status by the
Internal  Revenue  Service.  Management  believes  that  the Plan  currently  is
designed and operates in accordance with the applicable requirements of the Code
and  therefore  remains  exempt from federal  income taxes under  provisions  of
Section 501(a) of the Code.

Note 2 - Investments:

     General.  The  assets  of the  Plan are  held  and the  related  investment
transactions  are  executed by Putnam  Fiduciary  Trust  Company as trustee (the
"Trustee")  of the CompX  Master  401(k)  Plan  Trust (the  "Trust").  The Trust
invests in publicly-traded  registered investment  companies,  commingled trusts
administered by Putnam  Investments and CompX  International Inc. class A common
stock  (see  Note 1).  The Plan  assets  invested  in  Putnam  mutual  funds and
commingled  trusts  qualify  as  party-in-interest   transactions.   The  Plan's
investments  are  stated at fair  value  based on quoted  market  prices and net
appreciation for the year is reflected in the Plan's statement of changes in net
assets available for plan benefits.  The net  appreciation  consists of realized
gains or losses and unrealized  appreciation  or  depreciation  on  investments.
Purchases and sales of securities are recorded on a trade-date basis.  Dividends
are recorded on the ex-dividend date.

     The following presents  investments that represent 5 percent or more of the
Plan's net assets at year end:
