BOLT TANK 5/16 BSF 1/2
A 5/16 BSF, 1/2 inch tank mounting bolt, part number 21-6050.
This is a 21-6050, a 5/16 BSF bolt used for mounting a fuel tank. It's a small, plain hardware item — the kind of bolt you don't think about until it's stripped, rusted, or missing from the parts drawer.

The catalog entry on this one is brief, so we're not going to stretch it into more than it is. It's a tank bolt with a 5/16 BSF thread, and the length shown in our records is 1/2 inch. Beyond that, we don't have more detail on file.
If you're replacing tank mounting hardware, it's worth having a couple of these on hand — a stripped or corroded tank bolt is an easy fix as long as you've got the right thread. Call the shop and we'll confirm fitment before you order if you're not sure this is the one your tank takes.
