Bolt, chainwheel to drum (5/16" Unified Fine × 35/64")
A 5/16 inch UNF bolt that secures the rear chainwheel to the brake drum on the rear wheel assembly.
This is the bolt that fastens the rear chainwheel (sprocket) to the brake drum on the rear wheel assembly. It's a small but important piece of hardware — it's what keeps the sprocket carrier locked to the drum so the wheel and drive train stay in sync when the chain pulls.

The catalog lists it as a 5/16 inch Unified Fine bolt at 35/64 inch length, and it shows up in the rear wheel section of the parts books across appearances from 1969 to 1970. If you're rebuilding a rear wheel or chasing a wobble or noise from the sprocket area, these bolts are worth checking for wear or stretch, since they take a fair bit of load over time.
We don't have more detail on this one beyond what's in the parts book listing. If you're not sure your rear wheel takes this exact bolt, give us a call and we'll confirm before you order.
