A 1/4 inch UNF, 5/8 inch long screw for the heat shield/silencer fitting on early U.S.A.-spec 1969 first-run sets.
This is a screw used on the heat shield/silencer fitting for U.S.A.-spec machines from the first production sets in 1969, per the catalog listing. It's a 1/4 inch UNF screw, 5/8 inch long, and shows up in the parts book under the OIL TANK, SIDECOVERS, SILENCER figure grouping.

Given the figure titles, it's the kind of hardware that holds a heat shield in place near the exhaust/silencer area, keeping it snug against vibration. The catalog only shows it appearing once, tied to that first-run U.S.A. batch, so if you're chasing an exact match for a later production run, it's worth double-checking against what's actually on the bike.
Also listed under the older form 21-761. If you're not sure this is the exact screw your heat shield uses, give the shop a call and we'll confirm before you order.
