Quick facts
- Part: Dorman 981-521D bolt
- Material: Steel
- Condition: New
A bolt that is rusted, stripped, rounded at the hex head or loose in its joint may be due for replacement. A loose joint on its own does not show the bolt is at fault; a worn bracket or a damaged threaded hole is another common cause.
Fits
