STUD,CYLINDER HEAD T150
Outer cylinder head stud for the Triumph T150 Trident, part number 21-0686.
This is a cylinder head stud for the Trident T150, part number 21-0686. Studs like this hold the cylinder head down onto the barrels, and they take the clamping load every time the engine runs, so they need to be straight and in good shape before you torque a head back down.

The catalog references this one as an outer head stud for the T150 and its A75R sibling. If you're rebuilding a top end on one of these triples, it's worth checking all the studs for stretch or thread damage rather than just replacing the ones that look obviously bad, since a head that won't seal evenly can cause you grief down the line.
We don't have a lot more detail on file for this one beyond the catalog listing, so if you're not sure this is the exact stud your engine needs, give us a call and we'll confirm before you order.
