Warp 9 M8 x 32 CST45 Sprocket Bolt

Sprocket bolt with M8 x 32 and CST45 designations.

Sprocket bolts sit in chain lube, grit and water, and they have to come out every time gearing is changed. The thread seizes if they are left in long enough, and a loose one will enlarge its hole in the carrier before you notice the sprocket has started to move.
