Washer - Front and centre stays to bracket
A 5/16 inch flat washer with a reduced outer diameter, used at bolted joints across many areas of the bike including front and centre stays to bracket.
This is a flat washer, 5/16 inch, listed in the parts books as fitting under bolts and nuts at the front and centre stays where they meet their mounting bracket. It's a small, reduced-outer-diameter washer, made to sit properly under a bolt head or nut without crowding surrounding hardware.

The part shows up across a huge range of figures in the catalog - frame, fenders, mudguard stays, footrests, petrol tank, gearbox outer cover, timing cover, and more - which tells you this is one of those general-purpose fasteners Triumph used all over the bike wherever a 5/16 stud or bolt needed a washer with a tighter fit under the head. It carries forward from an older factory number, 71-0245, so if your parts book or an old invoice shows that number, it's the same washer.
Given how many places this one turns up, it's worth keeping a few on hand rather than hunting one down mid-job. The catalog record doesn't tie it to one specific spot, so if you're chasing an exact fitment for your build, we can help confirm which figure applies to what you're working on.
