ENGINE PLATE BOLT 3/8X26
3/8x26 engine plate mounting bolt, PN 82-1031, superseding the earlier 82-5535.
This is the 82-1031 engine plate bolt, a 3/8x26 fastener used to secure the engine mounting plate to the frame. The catalog description calls it out plainly: 3/8 diameter, 26 threads per inch, in the engine plate bolt family common to Triumph twins of this era.

Our records show this number superseded the earlier 82-5535, so if your parts book or an old invoice lists 82-5535, that's the same physical bolt under its older factory number. Beyond the thread spec we don't have much more detail on file for this one.
If you're not sure which of the several engine plate bolts your frame calls for, bring in the old one or check your parts book by figure before ordering.
