Looking to buy some vintage 'ROCKALLOY" brand Grade 8 bolts in the sizes listed below.
They were cad. plated, when new. Need fine threads.
I'd buy NOS or decent used.
Let me know what you have and what you need for them.
PM please - thanks!

Those were made by Rockwell, a defense contractor, and they are still around. North American Rockwell these days. The holes in the heads were for a wire tie as this type of bolt was not used with lock washers. Bolts were too hard to allow the lock washer to get a bite.
