Topic: CB750 Exhaust/Footpeg bolt size

[edwardmorris]

Search isn't helping much, anyone have one of these laying around and can measure the length? Its the long shouldered M12 bolt that holds the HM300/341s together along with the pillion footrests.

5 13/16".  Threads are only 5/8".

Thanks Danyo!

OK, can't find close matches in Metric Stainless, thinking about replacing with standard 1/2x6x20 fine thread ones, thoughts anyone?

SAE bolts on a CB?  Cmon man!

I bought a couple used ones recently from a members or a reasonable cost.

 I bet your buddy JTMarks has a couple!

haha, its a bit late for that, the custom rear brake actuator is all standard thread stainless. Want to use stainless ones, JT's always a back up plan

I would rather keep them zinc plated than mixing standards. Or maybe plate them nickel or chrome. I knew you want your hardware stainless but those are special screws and for sure not possible to find in SS.

 I may may have a set of NOS with a bit of shelfware.. good plating. I think the threads are smaller than the shoulder, so to use stainless you would have to turn down and rethread, os slip a bushing over it. Plus the haed would probabably be oversize.
Your prototype adjuster nut is nearly ready, but no camera to take a pic...
