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.

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.
