Features and Benefits
Flat washers are standard washers used for general-purpose fastening. They are placed under the head of a bolt or above a nut to distribute clamping force and prevent fasteners from pulling through materials.
Alloy steel is the strongest of all steel types. It has high tensile strength and offers excellent resistance to wear, fatigue and galling.
