This bolt is pictured as found, after cleaning of course.
Unsure of its correctness but I thought it was interesting as I haven't observed any others with this marking on the head.
Posting it as "might be interesting" that's all.
Documenting as found bolts is of interest to me and may be to others.
I just wanted to document as many fasteners as possible.
Seems the mechanical stuff it well documented, the bolts not so much.
The Head

Length and captive star washer.

Location on the bell-housing.

Needs to be painted orange to be correct.
