Screw (5/8 in. U.H.)
A 5/8 in. U.H. screw used in the twinseat, rear panels, and exhaust system fittings, listed under 82-4511 (formerly F4511).
This is a screw listed in the Triumph parts books under 82-4511, with the older-style alias F4511 turning up in earlier catalogs. It's called out in the TWINSEAT, REAR PANELS AND EXHAUST SYSTEM figure, so it's one of the small fasteners used to hold the rear bodywork and exhaust-area trim together rather than anything structural in the engine or gearbox.

The catalog lists it as a 5/8 in. U.H. screw. Beyond that we don't have more detail on this one - the record doesn't spell out exact thread pitch or finish, so if you're matching an original fastener, bring the old one along or have your bike handy to compare before ordering.
Catalog appearances tie it to the 1963-1964 span in our records. Call the shop and we'll confirm fitment before you order if you're not certain this is the right length for your seat or rear panel mounting.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
