Dorman Bolt P/N:960-407D
Dorman 960-612D bolt is a Grade 8 hex bolt that clamps parts together and holds them in place. Each Dorman bolt in the pack suits a variety of jobs, from auto to home.
A hex head with rounded flats, rusted or stripped threads, or a bent shank can mean a bolt needs replacing. Before ordering, look at the threads in the hole and measure the old bolt's length and thread pitch with the engine off and cool. If the hole is the damaged part, a new bolt will not hold in it.
This is universal hardware, sold by its size and thread rather than by application. Match the 5/16-18 thread and 1-1/4 in. length to the bolt you are replacing; the pack holds four bolts.
