Subject:  Final Report for 10 CFR Part 21 Courtesy Notification - Heavy

          Hex Bolts/Trace Code M2



Reference:     Facsimile/Mailed Correspondence to U.S. Nuclear Regulatory

               Commission Dated January 31, 1997, Same Subject



               Mailed Correspondence to U.S. Nuclear Regulatory

               Commission Dated February 14, 1997, Same Subject



To Whom It May Concern:



This letter provides to the Nuclear Regulatory Commission a courtesy

notification final report as referenced by 10 CFR Part 21, paragraph

21.21, (4).



ACCUTECH, a division of B&G Manufacturing Co., Inc. ("B&G"), recently

determined that heavy hex bolts supplied by the now defunct Cardinal

Industrial Products, L.P. ("CIP") in 1992 may be nonconforming.



On July 10, 1995, B&G purchased the name and certain other assets from

CIP, a limited partnership that had been formed and operated in Nevada.

B&G began its own nuclear fastener business at the same Nevada site and

temporarily used the "Cardinal Industrial Products" name before

officially adopting the trade name ACCUTECH in December, 1995.



We believe this situation may have been caused by insufficient heat

treating performed by CIP at the Nevada site, but we have no evidence

that these parts are nonconforming.  The heavy hex bolts under discussion

are trace code M2.  The suspect product was shipped to two (2) CIP

customers during 1992.  Both affected CIP customers were formally

notified of this specific situation on January 31, 1997.



It was determined that the subject heavy hex bolts may be suspect because

they were heat treated at the same time as capscrew blank trace code K7

which was reported to the Nuclear Regulatory Commission and affected CIP

customers as being nonconforming.

contained in the 10 CFR Part 21 Courtesy Notification dated May 8, 1996.



Even though B&G is not bound to take formal action under 10 CFR Part 21,

and the obligations for 10 CFR Part 21 statutory notifications remains

with CIP, as a courtesy B&G is providing this final investigation report

to the NRC.

                              FINAL REPORT



                              INTRODUCTION



On January 3 )O, 1997, ACCUTECH, a division of B&G Manufacturing Co.,

Inc.  ("B&G"), determined that heavy hex bolts trace code M2 supplied by

the now defunct Cardinal Industrial Products, L.P. ("CIP") in 1992 may be

nonconforming.



                               THE PROBLEM



It was determined that the subject heavy hex bolts may be suspect because

they were heat treated at the same time as capscrew blank.  trace code K7

which was reported to the Nuclear Regulatory Commission and affected CIP

customers as being nonconforming.  The appropriate reporting action for

the trace code K7 incident is contained in the 10 CFR Part 21 Courtesy

Notification dated May 8, 1996.



It is believed that this situation may have been caused by insufficient

heat treating performed by CIP at the Nevada site, but we have no

evidence that these parts are nonconforming.  The trace code M2 product

was shipped to two (2) CIP customers during 1992.  Both affected

customers were formally notified of this specific situation January 31,

1997.



                            THE INVESTIGATION



It was determined that trace code M2 parts were heat treated at the same

time as trace code K7 parts during a recreation of heat treatment

conditions conducted on September 16, 1995 pursuant to investigation

activities/findings associated with NRC Event No.  29257 submitted as a

final report to the Nuclear Regulatory Commission on November 21, 1995.



Both M2 and K7 trace code parts were processed at the same time during

the heat treatment recreation process conducted on September 16, 1995

under the control of "As Quenched Heat Treat Charge Analysis" Test Charge

ZBG-TEST-16.



Because of subsequent findings reported to the Nuclear Regulatory

Commission on May 8, 1996 indicating that trace code K7 parts (Lot No.

507597A) had test results which indicated nonconforming hardness, it is

assumed that trace code M2 parts may be suspect.

                        INVESTIGATION CONCLUSION



Since all manufactured trace code M2 parts were shipped by CIP to their

then customers in 1992 and the fact that no remaining inventory existed

at B&G's Nevada facility on January 30, 1997 to perform hardness tests,

it is not possible to determine if these suspect parts are nonconforming.
