Quick facts

Part: Dorman 784-758D nut
Fits: Universal hardware, matched by thread size and height
Material: Steel
Condition: New

A nut that spins on too freely, damaged threads or rust can mean the nut is worn, though a stretched bolt or a worn threaded hole can be behind the same looseness. Look at all three before you replace anything.

Fits

This nut is sold by size, not by application. Match the 3/8-16 thread and the 29/64 in height to the nut you are replacing.
