BSA STUD,A65 ROCKER BOX
Rocker box stud for the BSA A65 cylinder head, used to secure the rocker box/cover assembly.
This is a rocker box stud for the BSA A65, not a Triumph part despite where it lives in our catalog. The description ties it directly to the A65 cylinder head and rocker gear, and it shows up in the CYLINDER HEAD and CYLINDER HEAD — ROCKERS figures in the books.

A stud like this holds the rocker box or rocker cover down to the cylinder head, giving the assembly a solid mounting point that a bolt alone through soft castings wouldn't hold as well over time. It's a small, easy-to-overlook part but worth checking closely if you're pulling a head apart, since studs pull threads or snap more often than the covers they hold.
Our catalog record for this one spans appearances from 1969 to 1972 across four rows, all pointing at the same A65 rocker box location. If you're not sure which stud position or length you need for your rocker box, give us a call before ordering.
