Dorman Bolt P/N:962-610D
Dorman 960-610D bolt is a Grade 8 hex bolt that clamps parts together with a 5/16-18 fine thread.
Stripped threads, heavy rust or a rounded head can mean the bolt is worn, though a damaged threaded hole or a worn nut can also leave a joint loose, so look at those before you replace the bolt.
This is universal hardware, chosen by size and thread rather than by application. Match the 5/16-18 thread and the 1 in length to the bolt you are replacing.
