This is a small inspection cover screw, catalog code 2B, listed under Triumph part number 70-8177. It's a fastener that holds down an inspection cover, the kind of small round or timing cover plate you pop off to check points, timing marks, or rotor position without pulling the whole cover.

Our records show this number was later superseded by 57-1150, so if your parts book or an older bike shows 70-8177 and a newer reference shows 57-1150, they're the same part under two different numbers.
We don't have much more detail on file for this one beyond the description and the number change. If you're not sure this is the exact screw your cover needs, bring the old one in or give us a call before ordering.
Sorry if we got something wrong here. If you think this information isn't correct, .
