Which is stronger: a fine-thread bolt or a coarse-thread bolt?
I'm adding a spray rig to the back of a Polaris ATV quad bike, and i'd like to know: which one is a stronger bond? fine-thread or coarse-thread? i have both, so it's a toss-up.
anyone know? a web link would be appreciated, too.

Bolt strength (tensile) is indicated by marks on the crown of the bolt.
The more marks, the higher the tensile strength.

It's the grade that determines the shear strength. Fine thread is used where more precise tightening is desired, such as a cylinder head on an engine. It allows for more even torquing.

coarse thread bolt should be stronger
