Able to withstand temperatures up to 500° F, these are among the most heat resistant plastic washers we carry. They have excellent tensile strength for high-stress applications and good resistance to moisture and chemicals.

As you tighten a bolt, these metric washers flatten to add tension to the threaded joint and prevent loosening from small amounts of vibration. All of these washers meet a DIN or ASME standard for split lock washer dimensions.

Curved and wave split lock washers can be used with bolts that have right- or left-hand threads to prevent clockwise or counterclockwise rotation from vibration. Although they don’t grip as tight as standard split lock washers for applications with clockwise rotation, they are best for those with counterclockwise rotation. These washers retain their shape when untightened and will not damage nuts and bolts, so all can be reused.

Steel washers are stronger and more wear resistant than zinc-plated steel and stainless steel. Use them in dry environments because they will rust in wet and corrosive environments.

Also known as jig bushings, these metric drill bushings fit inside fixture plate holes to guide drill bits, counterbores, reamers, and other cutting tools. They improve accuracy so that your drilled holes and cuts are consistent from part to part. Known for their versatility, drill bushings are also used as spacers, shims, and machinery bushings. These bushings are made of hardened, ground steel that holds its shape and resists wear, so they last for many cycles without needing to be replaced.

All bushings have a chamfer on the outside that centers the bushing as you place it into the hole. Press into place with a manual or hydraulic press. They also have internal chamfers, so it's easier to insert bits, pins, and punches into the bushing. Some bushings have internal chamfers on both ends, so no matter which end of the bushing is inserted into your jig, your bits, pins, and other tooling enter easily. Having an internal chamfer on the bottom of your bushing may cause shavings to get caught and bind as you remove the bit, however.

DIN 179 bushings meet dimensional and material standards that make sure they're compatible with other parts and tools. Although DIN 179 is no longer an active standard, it's still a common reference point for designers.
