Quick facts
- Part: Dorman 784-334D washer
- Material: Steel
- Condition: New
A washer that is flattened, cracked or corroded, or a joint that keeps loosening, can mean the washer needs replacing. These signs alone do not prove the washer is at fault, since a worn bolt thread can loosen a joint just the same.
Fits
This is universal hardware sold by size, not by application. It is a direct replacement for the original washer used in numerous jobs, so match the 3/8 in size, along with the thread and length of the fastener, to the washer being replaced.
