The catalog data ties this to Norton engine work rather than anything Triumph, so if you're sorting parts from mixed boxes, keep this one with your Norton engine hardware. Beyond that, our record is a plain "washer" entry without extra detail on size or material.
If you're trying to match this against what's currently on your engine, bring the old washer to the counter or give us a call before you order so we can confirm you're getting the right one for the bolt or stud it needs to sit under.
