Oversized Washers
Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses for covering oversized holes or for use as spacers and levelers.
18-8 stainless steel and 17-4 PH stainless steel washers have good chemical resistance and may be mildly magnetic.

Washers for Structural Applications
Designed for use with structural screws, studs, and nuts, these washers are often used for construction and exterior building applications.
Hot-dipped galvanized washers are corrosion resistant in wet environments.

Split Lock Washers
As a screw is tightened, these washers flatten to add tension to the joint, counteracting fatigue around the joint from small amounts of vibration. This makes them a common choice to prevent fasteners from loosening. However, they resist the least amount of vibration compared to other locking washers.
These washers are compatible with fasteners that have right-hand threads to prevent loosening. The uneven split ends bite into fasteners for a tight grip, but they won’t work with hardened surfaces. These washers hold better than curved or wave washers. They are not reusable after tightening.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards.

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.
Stainless steel washers are more corrosion and chemical resistant than steel washers.

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.
