CASE BOLT BSA A65 -68 - 5/16-18 x 3.25 UH (Use 14-6226)
BSA A65 crankcase case bolt, 5/16-18 x 3.25 in., superseded by 14-6226.
This one's a crankcase bolt for the BSA A65, not a Triumph part despite what our system tag says — the catalog description spells it out plainly. It's a 5/16-18 thread, 3.25 inches long, with a U.H. head as noted in the parts book listing.

Our records show this number has been superseded — the listing tells us to use 14-6226 instead. If your parts book or an old inventory sheet still lists 21-1850, that's the number to cross-reference, but the part you'll actually receive and should order is 14-6226.
We don't have much more on file for this one beyond that superseded note, so if you're not sure which case bolt position you need, give us a call and we'll help confirm before you order.
Sorry if we got something wrong here. If you think this information isn't correct, .
