SUMP STUD 1/4 26 X1/4 20
A 1/4-26 x 1/4-20 stud used on Triumph pre-unit engines, listed under PN 70-1540.
PN · 70-1540
This is a Triumph stud, PN 70-1540, cut with 1/4 x 26 threads on one end and 1/4 x 20 threads on the other. The catalog calls it a sump stud, though the same number turns up in other listings tied to rocker box duty, so it's worth confirming exactly where yours came out of the engine before you order a replacement.
