About Washers

Metric Oversized Washers
Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses. Use them to cover oversized holes, hold heavy fastening loads, or as spacers and levelers.
Plain steel washers are stronger, more wear resistant, and less costly than zinc-plated steel and stainless steel washers. They should not be used in wet or corrosive environments because they easily rust.
Washers that meet DIN and ISO specifications meet international standards for washer dimensions. ISO 8738 is formerly DIN 1440. ISO 7093 is formerly DIN 9021. Washers that meet DIN 1440 are also known as shaft washers and washers for clevis pins.

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.
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.

Weather-Resistant Rubber Sealing Washers
Sunlight, ozone, and water won’t affect these washers. They create a light duty seal around fasteners to prevent fluids from leaking and damp vibration.
FDA compliant washers are safe for direct contact with food.

Metal Sealing Washers
Also known as crush washers, these compress when tightened to form a tighter, more durable seal than rubber washers. They are commonly used to seal fluids such as oil and fuel. Washers are not reusable.
Copper washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive. Cellulose-filled copper washers are for low-torque applications since they’re easier to crush than standard copper washers.
