Description:

Dimensionally equivalent to the low carbon SAE flat washer counterparts, but with tighter tolerances on thickness, manufactured
from a higher grade of steel and heat-treated.

 

Advantages:

Designed to perform the same functions as low carbon SAE flat washers, but for use specifically with high-strength hardened steel
bolts.
