Mil. Spec. Washers
Choose these washers for their adherence to strict military standards for material and construction.
18-8 stainless steel and 321 stainless steel washers have excellent corrosion resistance in most environments. They may be mildly magnetic. Passivated 18-8 stainless steel washers have added protection against oxidation and corrosion. Black-oxide 18-8 stainless steel washers have a matte-black finish.

Mil. Spec. Split Lock Washers
Choose these washers for their adherence to strict military standards for material and construction. As a screw is tightened, they flatten to add tension to the joint and prevent loosening from small amounts of vibration.
18-8 stainless steel washers have excellent corrosion resistance in most environments. They may be mildly magnetic. Passivated 18-8 stainless steel washers have added protection against oxidation and corrosion.
