Triumph 500 650 Pre-unit Toolbox Screw Stainless bonneville t120

Triumph's part number should be 82-3875 or F3875.

Brand new, thread fit is perfect.  Machined from solid stainless steel billet, it will never rust or tarnish and hold its shine VERY WELL.  To fit mid-fifties/early sixties pre-unit Triumphs, to my knowledge.
