Mil. Spec. Washers
Choose these washers for their adherence to strict military standards for material and construction.
Aluminum washers are lightweight and have good corrosion resistance. 2024 aluminum washers are easy to machine. They are stronger and resist wear better than 1100 aluminum. They are commonly used in the aircraft industry and in veterinary and orthopedic equipment. Yellow-chromate plated 2024 aluminum washers are more corrosion resistant than 2024 aluminum with no finish.

Belleville Spring Lock Washers for Socket Head Screws
These washers have smaller outside diameters than standard spring lock washers to fit neatly under socket head cap screws. Also known as conical washers, these have a slightly cupped shape that gives them spring-like flexibility to grip tighter than split and tooth lock washers. They minimize loosening from wear, temperature changes, and vibration. Serrations on the top and bottom provide extra gripping power. Load-rated Belleville disc springs are also available.
Zinc-plated steel washers are corrosion resistant in wet environments.

Triple-Wave Washers
With three points of surface contact, these washers provide more stability than single-wave washers. They are curved and flexible to act like springs, compensating for tolerance variations and uneven surfaces. You can also use them to damp vibration.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
