Dorman Bolt P/N:981-625
Dorman 981-537 bolt is a flanged hex bolt that clamps two parts together and spreads the clamping load under its flange. These Dorman flange bolts are metric and have a hex drive.
Rust, a damaged thread or a rounded head are signs a bolt needs replacing. A loose joint alone does not prove the bolt is at fault; stripped threads in the mating part are another common cause.
This is universal hardware, sold by size and thread rather than by application. Match the M10-1.25 thread and 40 mm length to the bolt you are replacing; the pack holds three bolts.
