AMENDMENT NO. 26

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 (“CompX”). Items 2, 4, 5 and 6 of this Statement are hereby amended as set forth below. The Reporting Persons (as defined below) are filing this amendment as a result of a change in control of CompX as a result of the death of Harold C. Simmons on December 28, 2013.

Item 2.

Identity and Background.

Item 2 is amended and supplemented as follows.

(a) The following entities or persons are filing this Statement (collectively, the “Reporting Persons”):

·	NL Industries, Inc. (“NL”) as a direct holder of Class A Shares;

Kronos Worldwide, Inc. (“Kronos Worldwide”), Valhi, Inc. (“Valhi”), Valhi Holding Company (“VHC”), Dixie Rice Agricultural Corporation, Inc. (“Dixie Rice”), Contran Corporation (“Contran”), and the Harold Simmons Foundation, Inc. (the “Foundation”) by virtue of their direct or indirect ownership of NL;

Lisa K. Simmons by virtue of her being a co-trustee of the Family Trusts (as defined and described below), her position as a member of the Contran board of directors (the “Contran Board”), a member, director and president of the Foundation and a party to the Voting Agreement (as defined and described below in this Statement);

·	Serena Simmons Connelly by virtue of being co-trustee of the Family Trusts, her position as a member of the Contran Board, a member, director and executive vice president of the Foundation and a party to the Voting Agreement (as defined and described below in this Statement); and

·	Annette C. Simmons by virtue of her position as a member of the Contran Board, her direct and indirect ownership of Class A Shares and a party to the Voting Agreement (as defined and described below in this Statement).

By signing this Statement, each Reporting Person agrees that this Statement is filed on its, her or his behalf.

The following is a description of the relationships among the Reporting Persons.

Lisa K. Simmons and Serena Simmons Connelly are daughters of Harold C. Simmons. Annette C. Simmons is the widow of Harold C. Simmons and serves as independent executor of his estate, has the power to vote and direct the disposition of the shares held by the estate and is the designated legatee of such shares.

Substantially all of Contran's outstanding voting stock is held by trusts established for the benefit of Lisa K. Simmons and Serena Simmons Connelly, daughters of Harold C. Simmons, and their children (the “Family Trusts”), for which Ms. Lisa Simmons and Ms. Connelly are co-trustees, or is held directly by Ms. Lisa Simmons and Ms. Connelly or persons or entities related to them, including their step-mother Annette C. Simmons, the widow of Harold C. Simmons. Ms. Annette C. Simmons, Ms. Lisa Simmons and Ms. Connelly also serve as members of the Contran Board. Prior to his death on December 28, 2013, Mr. Simmons served as sole trustee of the Family Trusts. As co-trustees of each of the Family Trusts, Ms. Lisa Simmons and Ms. Connelly have the shared power to vote and direct the disposition of the shares of Contran stock held by each of the Family Trusts, and Ms. Lisa Simmons and Ms. Connelly each have the power to vote and direct the disposition of shares of Contran stock they hold directly or which is held by other entities related to them.

Under a voting agreement (the “Voting Agreement”) entered into effective February 3, 2014 by the voting stockholders of Contran, the size of the Contran Board was initially fixed at five (5) members; Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons (and, in the event of their death, their heirs) each have the right to designate one of the five members of the Contran Board; and the remaining two members of the Contran Board must consist of Contran management. The Voting Agreement terminates in February 2017 (unless Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons otherwise mutually agree), and the ability of Ms. Lisa Simmons, Ms. Connelly, and Ms. Annette Simmons to each designate one member of the Contran Board is dependent upon each of their continued beneficial ownership of at least 5% of the combined voting stock of Contran. In accordance with such Voting Agreement, each of Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons have been designated as members of the Contran Board as of February 3, 2014, along with two members of Contran management.

The Foundation is a tax-exempt foundation organized for charitable purposes. Lisa K. Simmons and Serena Simmons Connelly are the sole members of the Foundation, serve as two of the three the directors on the Foundation’s board of directors and are the president and executive vice president, respectively of the Foundation. They may be deemed to control the Foundation but disclaim all Class A Shares they do not hold directly.

Annette C. Simmons is the sole trustee of a trust of which the beneficiaries are her grandchildren (the “Grandchildren’s Trust”), and she has the power to vote and direct the disposition of the shares the trust holds. She disclaims beneficial ownership of any shares that this trust holds.

A trust for which Ms. Annette Simmons is one of the co-trustees is the holder of 100% of the outstanding shares of non-voting preferred stock issued by VHC.

Contran is the holder of 100% of the outstanding common stock of Dixie Rice and may be deemed to control Dixie Rice. Dixie Rice is the direct holder of 100% of the outstanding common stock of VHC and may be deemed to control VHC.

Lisa K. Simmons, Serena Simmons Connelly and Annette C. Simmons are related to the following persons or entities that directly hold the following percentages of the 2,397,107 Class A Shares outstanding as of the close of business on February 5, 2014 based on information from CompX (the “Outstanding Class A Shares”):

NL	31.5	%
Annette C. Simmons as the independent executor of the estate of Harold C. Simmons and the designated legatee of his Class A Shares	15.1	%
Annette C. Simmons	2.5	%
Contran	0.2	%
Kronos Worldwide	0.1	%
Serena Simmons Connelly	0.1	%

NL also directly holds 100%, or 10,000,000 shares, of CompX’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 relative rights of the Shares are described in Exhibit 3.1 to Amendment No. 1 to CompX’s Registration Statement on Form S-1 filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 4, 1998 (Reg. No. 333-42643), which is incorporated herein by reference. As a result of its ownership of 31.5% of the Class A Shares and 100% of the Class B Shares, NL directly holds approximately 86.8% of the combined voting power (98.4% of the combined voting power for the election of directors) of all classes of voting stock of CompX. NL may be deemed to control CompX.

Lisa K. Simmons, Serena Simmons Connelly and Annette C. Simmons are related to the following persons or entities that directly hold the following percentages of the outstanding shares of NL common stock:

Valhi		83.0	%
Annette C. Simmons as the independent executor of the estate of Harold C. Simmons and the designated legatee of his shares of NL common stock		2.2	%
Annette C. Simmons		0.9	%

Annette C. Simmons		0.2	%
The Grandchildren’s Trust	Less than 0.1%
Serena Simmons Connelly	Less than 0.1%

VHC may be deemed to control Valhi. Contran may be deemed to control VHC, by virtue of its ownership of Dixie Rice shares.

NL (including a wholly owned subsidiary of NL) and Kronos Worldwide own 14,372,970 shares and 1,724,916 shares, respectively, of Valhi common stock. As already stated, Valhi is the direct holder of approximately 83.0% of the outstanding shares of common stock of NL and 50.05% of the outstanding shares of Kronos Worldwide common stock. As a result of Valhi’s direct and indirect ownership of NL and Kronos Worldwide and pursuant to Delaware law and Section 13(d)(4) of the Exchange Act, Valhi treats the shares of Valhi common stock that NL and Kronos Worldwide own as treasury stock for voting purposes. For the purposes of this statement, such shares of Valhi common stock that NL and Kronos Worldwide hold are not deemed outstanding.

By virtue of the stock ownership of each of Kronos Worldwide, NL, Valhi, VHC, Dixie Rice and Contran, the role of Ms. Lisa Simmons and Ms. Connelly as co-trustees of the Family Trusts, Ms. Lisa Simmons and Ms. Connelly being beneficiaries of the Family Trusts, the direct holdings of Contran voting stock by each of Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons and entities related to them, the position as a member of the Contran Board by each of Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons, the position as a member of the board of the Foundation by each of Ms. Lisa Simmons and Ms. Connelly, and the rights of each of Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons under the Voting Agreement, in each case as described above, (a) Ms. Lisa Simmons and Ms. Connelly may be deemed to control each of the Family Trusts and the Foundation, (b) Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons may be deemed to control each of Contran, Dixie Rice, VHC, Valhi, NL, Kronos Worldwide and CompX and (c) Ms. Lisa Simmons, Ms. Connelly, Ms. Annette Simmons, Contran, the Foundation, Dixie Rice, VHC, Valhi, NL and Kronos Worldwide may be deemed to possess indirect beneficial ownership of, and a pecuniary interest in, shares of common stock directly held by such entities, including any Shares.
