Bolt, bracket to fork lug
A 5/16 UNF, 5/8 in. under-head bolt used at multiple bracket-to-frame and bracket-to-lug points across the bike.
This is a bolt that turns up all over the parts books, tying the fork lug (swinging arm pivot area) to its bracket, but it also shows up in figures for fenders, exhaust mounting, gas tank and seat, and even the frame itself. That spread tells you it's a general-purpose fastener Triumph used wherever a 5/16 UNF bolt of this length did the job, not a part that lives in just one spot on the bike.

Given how many different figures it shows up in across the catalog, from swinging arm and suspension work to mudguard and exhaust bracketry, it's worth checking your own parts book or figure diagram to confirm which specific bracket you're bolting up before you order a batch.
It's cataloged as a 5/16 UNF bolt with a 5/8 in. under-head length. If you're replacing hardware on any of these areas, matching the thread and length to what's coming out is the main thing to get right.
