About Washers

Metric General Purpose Washers
Use these metric washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.
Stainless steel washers are more corrosion resistant than steel washers, and almost as strong. 18-8 and 17-7 PH stainless steel washers will hold up in humid, damp, and washdown environments, but will corrode if exposed to salt water or chemicals. 17-7 PH stainless steel washers are stronger than 18-8 stainless steel.

Spring Lock Washers for Slotted Bearing Nuts
Designed for use with bearing nuts, these lock washers have a conical shape that presses like a spring against bearings, bushings, gears, and pulleys to hold them in place on your threaded shaft or spindle. They also have an inner tab that sits in the shaft or spindle’s keyway to prevent the nut from loosening.
Steel washers are strong and flexible.
Washers with external teeth grip components using their teeth, in addition to spring tension.
DIN 462 and DIN 5406 washers meet international standards for lock washer dimensions. Pair DIN 462 washers with DIN 1804 bearing nuts, and DIN 5406 washers with DIN 981 bearing nuts.

Wedge Lock Washers
These two-piece washers provide more locking power than split, tooth, and spring lock washers. Wedges on the inside lock the two pieces together, and serrations on the exterior grip surfaces to resist loosening from high vibration and shifting. Washers are reusable.
Zinc-flake-coated steel washers are corrosion resistant in wet environments.
316 stainless steel and zinc-flake-coated steel washers are comparable to NORD-LOCK® Series washers.
