Caliper hanger bolts
What is a source for the 10 x 35 mm (1.25 mm pitch) bolts that attach the caliper hangers to the lower fork legs?
I've bought two sets of SP-2 forks to try to make up one good set for installation on my VFR800. The bolts that came with each set I purchased were beat up and rusted beyond belief.
Both sets of forks I purchased had one 10 x 35 bolt in one hole and one 10 x 25 in the other. The 10 x 25 bolt has about 3 courses of threads sticking out once it passes through the hanger.
I know these aren't you're standard run of the mill bolts. My guess is that they are at a minimum Grade 10.9 or maybe even 12. It's been my experience with other Honda's that they tend to use grade 10.9 bolts on brake hardware. Might also explain the reason they are Torx type heads.
If you go to RonAyers.com and look on the parts fiche, this part number is called out as a 10 x 25 bolt, part #901010-MCF-000.
The two bolts really need to be a 10 x 35 and a 10 x 40 to get full thread engagement into the ears on the fork legs. The only place I've found bolts of this size and thread pitch is on ProBoltsUSA. Problem is they only carry 316 stainless steel bolts in this size and pitch. I know for a fact that 316 stainless is not as strong as a Grade 10.9 bolt.
I have searched the web high and low.
Any input, comments, or ideas are welcome.
