Re: Makers marks on OEM bolts

Yesterday I installed a cool little 3/8 bolt for the distributor hold-down. It's the only one like it off the truck. Recessed head flange bolt, 3/8-16 x 9/16", stamped "E". Not tapered.

Few weeks ago I installed a bolt marked with a triangle for an A/C support bracket. Kind of cool, because the bracket is stamped with a triangle as well, almost as if it were a kit.
