Grade 8 Torx bolts? : V-Twin Forum: Harley Davidson Forums

I started to replace all of the Torx bolts on my WG this afternoon and when I pulled the first one out of the triple tree I noticed that it was marked “HD8” Does anyone know if HD uses grade 8 bolts or if this is a meaningless marking? I would hate to use ungraded Allen bolts if I need a graded bolt and if it is a grade 8 then are graded Allen bolts available? I can’t say that I ever paid attention to grading whenever I bought Allens.

They use Grade 8 fasteners when so marked. For example the cap screws that hold the foot pegs to the frame are also Grade 8.

You really need the parts manual. It will tell what the grade of the various bolts are.
