Washer plain - bolt
A 5/16 inch plain flat washer used under bolts and nuts across many Triumph fixing points.
This is a plain flat washer, 5/16 inch, used under a bolt or nut head wherever the parts book calls for one. It shows up across a wide range of Triumph fittings figures — motor mounting points, footrests, petrol tank fixings, mudguard fixings, frame fittings, and swinging arm and suspension hardware — which tells you it's a general-purpose piece of hardware rather than something built for one specific job.

The older book number for this same washer is D2321, so if you're working from an earlier parts list and see that number, it's the same part as 60-2321.
Given how many different fixings it turns up under, keep a few of these on hand. It's the kind of washer you'll want when you're reassembling tank mounts, footrest brackets, or suspension hardware and find the original has gone missing or buggered up.
