Dorman Bolt P/N:981-637
Dorman 981-551D bolt is a hex-head cap screw that clamps parts together through an M10-1.25 thread.
A stripped thread, a rounded head or rust on the shank can mean a bolt has reached the end of its life. A worn bracket or a damaged threaded hole can be behind a loose fastener too, so find the cause before buying a new bolt.
This is universal hardware, sold by size and thread rather than by vehicle. Match the M10-1.25 thread, the 50 mm length and the hex head to the bolt you are replacing.
