Washer – outer cover bottom stud (·344" X ·625" X ·063")

Flat washer for an outer cover bottom stud, .344 in. x .625 in. x .063 in., Triumph engine hardware, PN 21-0025.

PN · 21-0025

This is a flat washer specific to Triumph engine work, used at the bottom stud on an outer cover. The catalog lists it at .344 in. inside diameter, .625 in. outside diameter, and .063 in. thick, so it's sized to seat properly under the nut or bolt head at that particular stud location without crushing or slipping.
