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.
Brass washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

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.
In addition to resisting rust in wet environments, copper and brass washers are electrically conductive. Nickel-plated brass washers have a decorative finish.

ASME Washers
Also known as Type B washers.
Narrow washers have a smaller OD than regular and wide washers for applications where SAE and USS washers won’t fit. Regular washers have a larger OD than SAE washers. They’re generally as large as or larger than USS washers.
Copper and brass washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive. Brass washers are nickel plated for a decorative finish.

Corrosion-Resistant Flanged Screw-Clamp Bushings
Made from stainless steel or plated with nickel, these bushings resist corrosion. A mounting flange prevents movement during tightening. As screw-clamp bushings, they're good for shock loads. When you tighten the clamping screws, the bushing's inner sleeve tightens onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear.
Nickel-plated steel bushings have good corrosion resistance in wet environments. However, the plating may begin to flake with long-term use.

Corrosion-Resistant Flush-Mount Screw-Clamp Bushings
Insert these nickel-plated steel bushings into the bore of your sprocket for flush or recessed mounting in wet environments. When you tighten the included clamping screws on these bushings, their inner sleeve contracts onto the shaft and their outer sleeve expands to hold your sprocket, pulley, or gear. This keeps bushings from slipping during sudden starts and stops.
