FAQ

What is a spring washer?
A helical split (grower) washer that supplies spring tension to keep the nut tight.
Can I reuse it?
No; once flattened it loses its spring action — fit a new one.
Is it the same as a lock washer?
The spring washer is helical; the lock washer is toothed/split tab. Both are Class 8.8 steel.
