AMENDMENT NO. 50
TO SCHEDULE 13D

This amended  statement on Schedule 13D (this  "Statement")  relates to
the  common  stock,  $1.00  par  value per share  (the  "Shares"),  of  Keystone
Consolidated Industries,  Inc., a Delaware corporation (the "Company"). Items 2,
4, 5 and 6 of this Statement are hereby amended as set forth below.

Item 2.  Identity and Background

Item 2(a), 2(d), 2(e) and 2(f) are amended as follows:

(a) This Statement is filed by (i) Valhi, Inc.  ("Valhi"),  and Contran
Corporation ("Contran") as direct and indirect holders of Shares, (ii) by virtue
of the direct and indirect  ownership of securities of Valhi (as described below
in this  Statement),  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"),  The Combined Master Retirement Trust (the "CMRT")
and the Harold Simmons  Foundation,  Inc. (the "Foundation") and (iii) by virtue
of his positions  with Contran and certain other  entities (as described in this
Statement),  Harold C.  Simmons  (collectively,  the  "Reporting  Persons").  By
signing this  Statement,  each  Reporting  Person agrees that this  Statement is
filed on its or his behalf.

Contran, Valhi, NL Industries, Inc. ("NL"), the Foundation and the CMRT
are the direct  holders  of  approximately  40.8%,  3.2%,  3.2%,  1.9% and 0.3%,
respectively,  of the  10,068,450  Shares  outstanding  as of  October  9,  2003
according to  information  provided by the Company (the  "Outstanding  Shares").
Contran, Valhi and NL may be deemed to control the Company.

Contran is also the  direct  holder of 54,956  shares of the  Company's
Series A 10% Cumulative  Convertible  Pay-In-Kind Preferred Stock, $1,000 stated
value per share and no par value per share (the "Preferred  Shares"),  the terms
of which are set forth in the Amended and Restated  Certificate of Designations,
Rights and  Preferences of the Series A 10% Cumulative  Convertible  Pay-in-Kind
Preferred Stock of Keystone Consolidated Industries, Inc., which is incorporated
herein by reference to Exhibit 3.2 to the  Company's  Annual Report on Form 10-K
for the fiscal year ended  December 31, 2002, as filed with the  Securities  and
Exchange  Commission (the "Amended and Restated  Preferred Stock  Designation").
Contran has the right to convert all of its  Preferred  Shares into an aggregate
of 13,739,000 Shares. Assuming only Contran's conversion of its Preferred Shares
and Contran's  other direct holdings of Shares remain  unchanged,  Contran would
directly hold 75.0% of the outstanding Shares.

Valhi  and  Tremont  LLC   ("Tremont")   are  the  direct   holders  of
approximately 63.1% and 21.4%, respectively,  of the outstanding common stock of
NL and together may be deemed to control NL. Valhi is the sole member of Tremont
and may be deemed to control Tremont.

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%, 3.0%, 1.3%, 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 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  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 common stock of NOA and together may
be  deemed  to  control  NOA.  Dixie  Rice is the  direct  holder of 100% of the
outstanding  common  stock of Dixie  Holding and may be deemed to control  Dixie
Holding.  Contran is the holder of 100% of the outstanding common stock of Dixie
Rice  and may be  deemed  to  control  Dixie  Rice.  Contran  is the  holder  of
approximately  88.9% of the  outstanding  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.  As
sole trustee of each of the Trusts, Mr. Simmons has the power to vote and direct
the  disposition of the shares of Contran stock held by each of the Trusts.  Mr.
Simmons, however,  disclaims beneficial ownership of any shares of Contran stock
that the Trusts hold.

The Foundation  directly holds  approximately  1.9% of the  Outstanding
Shares and 1.3% 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 CMRT directly holds  approximately  0.3% of the Outstanding  Shares
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. Mr. Simmons is the sole trustee of the CMRT and a member of the
trust investment  committee for the CMRT. Mr. Simmons is a participant in one or
more of the employee benefit plans that invest through the CMRT.

The CDCT No. 2 directly  holds  approximately  0.4% of the  outstanding
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.

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  common  stock of  Valmont  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 of Tremont,  Valhi, VGI,
National,  NOA, Dixie Holding,  Dixie Rice, Southwest and Contran and a chairman
of the board and chief executive officer of NL.

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 Keystone
securities directly held by certain of such other entities. However, Mr. Simmons
disclaims  such  beneficial  ownership of the Keystone  securities  beneficially
owned, directly or indirectly,  by any of such entities, except to the extent of
his vested beneficial interest, if any, in the Shares held by the CMRT.

Harold C.  Simmons'  spouse is the direct owner of 10,645  Shares.  Mr.
Simmons may be deemed to share indirect beneficial ownership of such Shares. Mr.
Simmons disclaims all such beneficial ownership.

Certain information  concerning the directors and executive officers of
the Reporting  Persons,  including  offices held by Mr.  Simmons is set forth on
Schedule B attached hereto and incorporated herein by reference.

civil proceeding of a judicial or administrative body of competent  jurisdiction
as a result of which such  person was or is  subject  to a  judgment,  decree or
final  order  enjoining  future  violations  of,  or  prohibiting  or  mandating

with respect to such laws.

Statement are citizens of the United  States,  except as otherwise  indicated on
such Schedule.

Item 4.  Purpose of Transaction

Item 4 is amended as follows.

Prior  to the  filing  of the  Amended  and  Restated  Preferred  Stock
Designation,  the holders of Preferred  Shares were entitled,  on or after March
15, 2003, to cast the number of votes equal to the number of votes that could be
cast by a holder of the number of Shares  into which the  Preferred  Shares were
convertible  (without  regard  to  any  limitation  on  convertibility  of  such
Preferred Shares as a result of the number of authorized and unissued Shares) on
the record date of such vote.  However,  on March 18, 2003, after approval as of
March 14, 2003 by the holders of at least 66 2/3% of the issued and  outstanding
Preferred  Shares,  with notice to the other  holders of Preferred  Shares,  the
Company  amended  the rights of the  Preferred  Shares by filing the Amended and
Restated Preferred Stock Designation to make the Preferred Shares nonvoting.

Subject to the Company's restated  certificate of incorporation,  on or
after March 15, 2002,  each Preferred  Share entitled its holder to convert such
share into 250 Shares (a conversion  price  equivalent to $4.00 per share of the
stated  value).  However,  prior to  October  9, 2003,  the  Company's  restated
certificate of incorporation only allowed for the issuance of 12,000,000 Shares,
which would not permit full  conversion  of all of the  Preferred  Shares.  As a
result, the Company sought stockholder  approval of an increase in the Company's
authorized Shares to allow for the full conversion of the currently  outstanding
Preferred Shares. On October 2, 2003, the Company's stockholders approved, among
other  things,   an  amendment  to  the  Company's   restated   certificate   of
incorporation authorizing the issuance of 27,000,000 Shares. On October 9, 2003,
the Company filed an amendment to its restated certificate of incorporation with
the  Secretary  of State of the state of  Delaware  that,  among  other  things,
increased its authorized Shares to 27,000,000 Shares. Accordingly, on October 9,
2003,  the Company had a sufficient  number of authorized  Shares to permit full
conversion of all of the outstanding Preferred Shares.

Depending  upon  their   evaluation  of  the  Company's   business  and
prospects,  and  upon  future  developments  (including,  but  not  limited  to,
performance of Company securities (including Shares) in the market, availability
of funds,  alternative  uses of funds,  and  money,  stock  market  and  general
economic conditions), any of the Reporting Persons or other entities that may be
deemed to be  affiliated  with Contran,  may from time to time purchase  Company
securities,  and any of the  Reporting  Persons,  or other  entities that may be
deemed to be  affiliated  with Contran may from time to time dispose of all or a
portion  of the  Company  securities  held by such  person,  or cease  buying or
selling Company  securities.  Any such additional  purchases or sales of Company
securities  may be in  open  market  or  privately  negotiated  transactions  or
otherwise.

As described under Item 2, Harold C. Simmons,  through Contran,  may be
deemed to control the Company.

The  information  included in Item 6 of this Statement is  incorporated
herein by reference.

The Reporting Persons understand that prior purchases of Shares by each
of the persons  named in Schedule A to this  Statement and Mr.  Simmons'  spouse

Company sponsors or other compensation arrangements with the Company.

Except as described in this Item 4, none of the Reporting  Persons nor,
to the best  knowledge of such persons,  any other person named in Schedule A to
this  Statement has  formulated  any plans or proposals  that relate to or would
result in any matter  required to be  disclosed  in response to  paragraphs  (a)
through (j) of Item 4 of Schedule 13D.

only the conversion of the Preferred Shares currently held by Contran);
and

(5) While  Harold C. Simmons does not directly own any Shares,
he may be deemed to be the beneficial  owner of the  18,729,618  Shares
that  Contran,  Valhi,  NL,  the  Foundation,  the CMRT and his  spouse
directly hold (an aggregate of  approximately  78.7% of the outstanding
Shares assuming only the conversion of the Preferred  Shares  currently
held by Contran).

Except to the  extent  of his  vested  beneficial  interest,  if any,  in Shares
directly held by the CMRT, Mr.  Simmons  disclaims  beneficial  ownership of all
Shares.

The Reporting Persons  understand,  based on ownership filings with the
Securities  and  Exchange  Commission  (the  "Commission")  or upon  information
provided  by the  persons  listed on  Schedule  B to this  Statement,  that such
persons may be deemed to personally  beneficially own the Shares as indicated on

(b) By virtue of the relationships described in Item 2:

Southwest  may each be deemed to share the power to vote and direct the
disposition of the Shares that Valhi and NL directly hold;
