BSA Nut, connecting rod bolt (5/16" B.S.C.)

5/16 inch B.S.C. nut for the connecting rod bolt, used in the cylinder and crankshaft assembly.

PN · 40-0915

This is the nut that fits the connecting rod bolt, sized at 5/16 inch B.S.C. thread. It shows up in the parts book under the CYLINDER AND CRANKSHAFT section, meaning it's part of the hardware that clamps the connecting rod cap to the rod down at the bottom end of the engine.
