[TheForge] Bolt grade

Sat May 11 19:51:01 2002

Bobby,

Three radial marks makes it a Grade 5 bolt. This seems like a fairly strong bolt to use where failing is part of the plan but if that's what was in it (your machine) that's probably what it was designed for.

The triangle is probably the makers mark. "Infasco" a Canadian bolt company uses a triangle (just a side note).

Good luck.
