Be interesting to get the manufacturer insignia's on the graded cap bolts since they should have to marked under the Fastener Quality Act for traceability.
I been tracing whats left of the old Harbor Fright supplied bolt set I had. They were mostly marked BY but there was a few "J"
The BY mark is for
Ben Yuan Enterprise Co., Ltd. No. 113, Chi-Nan Rd., Ta-She Hsiang Kaohsiung Hsien Taiwan 81546 Corporation Registration Number: 1782394
The J on the other hand is long gone from the registry and is currently on a list of suspect counterfeit grade markings. And substandard grade markings especially for defense and industry mainly what was behind creating all this Federal registry stuff starting back in the late 80's
Some of the bolts mostly Grade 8 that I have sourced locally have been Rockford, Atlas stamped by name, And their are others that have this vertical split circle with horizontal center line which is MNP Corp Utica MI.
I do have many that have the triangle mark and that's listed as a Canadian source.
Looking around there is good number of US/North American addresses on the most current register 2017 and of course thee are overseas sources mainly Asian.
You can find some older registry links online with past marks
I remember once I guy I knew got a job working with some cable line installation concern and some of his bolts were marked OF
He says they must be a special bolt "OF" Overhead Fastener
Registry said OF was...
Oriental Fastener Co, China
THAT
