bolt head marking
bolt head marking
(OP)
Hi
I have a precision steel bolt M10 x 1.25 and it has a raised letter q on the head. I'm fairly sure this is Japanese. Can anyone tell me if this relates to the material strength or is it something else?
Thanks in advance

Though I have been searching and haven't found it.
I hope someone with a better memory than mine comes along.
I had thought that it was part of a DoD report on bogus fasteners...
