AMENDMENT NO. 10 TO SCHEDULE 13D This amended statement on Schedule 13D (this "Statement") relates to the class A common stock, par value $0.01 per share (the "Class A Shares"), of CompX International Inc., a Delaware corporation (the "Company"). Items 2, 3, 4 and 5 of this Statement are hereby amended as set forth below. Item 2. Identity and Background. Item 2 is amended as follows. (a) The following entities or person are filing this Statement (collectively, the "Reporting Persons"): (i) CompX Group, Inc. ("CGI") as a direct holder of Class A Shares; (ii) TIMET Finance Management Company ("TFMC") by virtue of its direct ownership of CGI and as a direct holder of Class A Shares; (iii) NL Industries, Inc. ("NL"), Titanium Metals Corporation ("TIMET"), Tremont LLC ("Tremont"), Valhi, Inc. ("Valhi"), Valhi Group, Inc. ("VGI"), National City Lines, Inc. ("National"), NOA, Inc. ("NOA"), Dixie Holding Company ("Dixie Holding"), Dixie Rice Agricultural Corporation, Inc. ("Dixie Rice"), Southwest Louisiana Land Company, Inc. ("Southwest"), Contran Corporation ("Contran"), The Combined Master Retirement Trust (the "CMRT") and the Harold Simmons Foundation, Inc. (the "Foundation") by virtue of their direct or indirect ownership of CGI and TFMC; and (iv) Harold C. Simmons by virtue of his direct and indirect ownership of Class A Shares and his positions with Contran and certain of the other entities (as described in this Statement). By signing this Statement, each Reporting Person agrees that this Statement is filed on its or his behalf. CGI and TFMC are direct holders of 50.0% and 3.3%, respectively, of the 5,169,880 Class A Shares outstanding as of December 6, 2004 according to information the Company provided (the "Outstanding Class A Shares").

CGI also directly holds 100%, or 10,000,000 shares, of the Company's class B common stock, par value $0.01 per share (the "Class B Shares" and collectively with the Class A Shares shall be referred to as the "Shares"). The description of the relative rights of the Shares as described in this Statement is qualified in its entirety by the terms of the Company's restated certificate of incorporation that is filed as Exhibit 3.1 to Amendment No. 1 to the Company's Registration Statement on Form S-1 filed with the Securities and Exchange Commission on February 4, 1998 (Reg. No. 333-42643), which is incorporated herein by reference. As a result of its ownership of 50.0% of the Class A Shares and 100% of the Class B Shares, CGI directly holds approximately 83.0% of the combined voting power (97.5% of the voting power for the election of directors) of all classes of voting stock of the Company. CGI may be deemed to control the Company. NL and TFMC are the direct holders of approximately 82.4%, and 17.6%, respectively, of the outstanding shares of CGI common stock and together may be deemed to control CGI. Valhi, Tremont and TFMC are the direct holders of approximately 62.2%, 21.1% and 0.5%, respectively, of the outstanding shares of NL common stock and together may be deemed to control NL. Valhi is the sole member of Tremont and may be deemed to control Tremont. TIMET is the direct holder of 100% of the outstanding shares of common stock of TFMC and may be deemed to control TFMC. Tremont, Harold C. Simmons' spouse, the CMRT and Valhi are the holders of approximately 39.6%, 14.4%, 12.0% and 1.3% of the outstanding shares of TIMET common stock. Tremont may be deemed to control TIMET. The ownership of Mr. Simmons' spouse is based on the 1,600,000 shares of TIMET's 6 3/4% Series A Convertible Preferred Stock, par value $0.01 per share (the "Series A Preferred Stock"), that she directly owns, which are convertible into 2,666,666 shares of TIMET common stock. The ownership of Valhi includes 24,500 shares of TIMET common stock that Valhi has the right to acquire upon conversion of 14,700 shares of Series A Preferred Stock that Valhi directly holds. The percentage ownership of TIMET common stock held by each of Ms. Simmons and Valhi assumes the full conversion of only the shares of Series A Preferred Stock she or Valhi owns, respectively. VGI, National, Contran, the Foundation, the Contran Deferred Compensation Trust No. 2 (the "CDCT No. 2") and the CMRT are the direct holders of 77.6%, 9.1%, 3.4%, 0.9%, 0.4% and 0.1%, respectively, of the common stock of Valhi. Together, VGI, National and Contran may be deemed to control Valhi. National, NOA and Dixie Holding are the direct holders of approximately 73.3%, 11.4% and 15.3%, respectively, of the outstanding shares of common stock of VGI. Together, National, NOA and Dixie Holding may be deemed to control VGI. Contran and NOA are the direct holders of approximately 85.7% and 14.3%, respectively, of the outstanding shares of common stock of National and together may be deemed to control National. Contran and Southwest are the direct holders of approximately 49.9% and 50.1%, respectively, of the outstanding shares of common stock of NOA and together may be deemed to control NOA. Dixie Rice is the direct holder of 100% of the outstanding shares of common stock of Dixie Holding and may be deemed to control Dixie Holding. Contran is the holder of 100% of the outstanding shares of common stock of Dixie Rice and may be deemed to control Dixie Rice. Contran is the holder of approximately 88.9% of the outstanding shares of common stock of Southwest and may be deemed to control Southwest.

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 (the "Trusts"), of which Mr. Simmons is the sole trustee, or held by Mr. Simmons or persons or other entities related to Mr. Simmons. As sole trustee of the Trusts, Mr. Simmons has the power to vote and direct the disposition of the shares of Contran stock held by the Trusts. Mr. Simmons, however, disclaims beneficial ownership of any shares of Contran stock that the Trusts hold. The Foundation directly holds approximately 0.9% of the outstanding shares of Valhi common stock. The Foundation is a tax-exempt foundation organized for charitable purposes. Harold C. Simmons is the chairman of the board of the Foundation and may be deemed to control the Foundation. The CDCT No. 2 directly holds approximately 0.4% of the outstanding shares of Valhi common stock. U.S. Bank National Association serves as the trustee of the CDCT No. 2. Contran established the CDCT No. 2 as an irrevocable "rabbi trust" to assist Contran in meeting certain deferred compensation obligations that it owes to Harold C. Simmons. If the CDCT No. 2 assets are insufficient to satisfy such obligations, Contran is obligated to satisfy the balance of such obligations as they come due. Pursuant to the terms of the CDCT No. 2, Contran (i) retains the power to vote the shares of Valhi common stock held directly by the CDCT No. 2, (ii) retains dispositive power over such shares and (iii) may be deemed the indirect beneficial owner of such shares. The CMRT directly holds approximately 12.0% of the outstanding shares of TIMET common stock and 0.1% of the outstanding shares of Valhi common stock. Valhi established the CMRT as a trust to permit the collective investment by master trusts that maintain the assets of certain employee benefit plans Valhi and related companies adopt. Harold C. Simmons is the sole trustee of the CMRT and a member of the trust investment committee for the CMRT. Mr. Simmons is also a participant in one or more of the employee benefit plans that invest through the CMRT.

Valmont Insurance Company ("Valmont"), NL and a subsidiary of NL directly own 1,000,000 shares, 3,522,967 shares and 1,186,200 shares, respectively, of Valhi common stock. Valhi is the direct holder of 100% of the outstanding shares of Valmont common stock and may be deemed to control Valmont. Pursuant to Delaware law, Valhi treats the shares of Valhi common stock that Valmont, NL and the subsidiary of NL own as treasury stock for voting purposes and for the purposes of this Statement such shares are not deemed outstanding. Mr. Harold C. Simmons is chairman of the board and chief executive officer of NL, vice chairman of TIMET and chairman of the board of CGI, Tremont, Valhi, VGI, National, NOA, Dixie Holding, Dixie Rice, Southwest and Contran. By virtue of the holding of the offices, the stock ownership and his service as trustee, all as described above, (a) Mr. Simmons may be deemed to control the entities described above and (b) Mr. Simmons and certain of such entities may be deemed to possess indirect beneficial ownership of the Shares that are directly held by CGI and TFMC. However, Mr. Simmons disclaims such beneficial ownership of the Shares beneficially owned, directly or indirectly, by any of such entities. Harold C. Simmons' spouse is the direct owner of 20,000 Class A Shares, 69,475 shares of NL common stock and 43,400 shares of Valhi common stock. Mr. Simmons may be deemed to share indirect beneficial ownership of such Shares. He disclaims all such beneficial ownership. Harold C.
