Torque stay washer
A torque stay washer used in the engine/frame mounting hardware, factory part 99-0046, later renumbered 60-4251.
This is a torque stay washer, catalog number 99-0046, a small hardware piece that shows up across a wide run of Triumph parts book figures dealing with the frame, swinging arm and rear suspension, engine mounting hardware, footrests, and the rear wheel. The torque stay is the bracket that ties the engine/gearbox unit to the frame to control movement under load, and this washer is part of the fastening hardware for that link.

Given how many different figure titles this washer turns up in, it looks like a common hardware item used at more than one fastening point rather than a single dedicated bracket washer. The catalog data spans 1969 through 1974 across a large number of listings, but we don't have specifics tying it to one exact model or year - if you're matching this against a particular bike, bring in your parts book page or give us a call and we'll confirm before you order.
If your parts book lists this under a different number, note that the factory later renumbered it to 60-4251. Both numbers refer to the same physical washer, so search whichever one is printed in your reference material.
