CENTER STAND BOLT 1954-62 650 - 1959-66 500 TRI
Center stand pivot bolt for pre-unit 650 and 500 twins, PN 82-3619 (formerly F3619).
This is the center stand bolt, PN 82-3619, also known by the older F3619 designation. It's the pivot bolt that the center stand swings on where it mounts to the frame. The catalog lists it against 650 twins from the mid-1950s into the early '60s and 500 twins running from the late '50s into the mid-'60s, so it's a pre-unit era piece.

If your center stand is loose, wobbly, or the pivot hole is worn oval, this bolt is one of the first things to check along with the stand itself and the frame lug it passes through. It's a simple fastener but it takes a lot of repeated stress every time the bike goes up on the stand, so a worn one is worth swapping out rather than living with play in the stand.
Given how far back this one's catalog listing goes, double check the number against what's stamped or listed in your own parts book before ordering, since pre-unit frame hardware sometimes changed across the years this bolt covers.
