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.
316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.
18-8 stainless steel washers have excellent corrosion resistance in most environments. They may be mildly magnetic.
Passivated stainless steel washers have added protection against oxidation and corrosion.
