Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses for covering oversized holes or for use as spacers and levelers.

SAE washers generally have a smaller ID and OD than USS washers.

Also known as Type B washers, these distribute your fastener's load over a larger surface area than other washers to minimize damage to soft materials.

Also known as backup washers, these are for use with blind rivets for extra support when fastening into soft material.

Clipped to fit where standard washers can't, these won't rotate when you position the flat edge against a flat surface.

Square washers fit into slots and channels and have flat sides to keep them from rotating.

A slot in the side allows you to install and remove these washers without completely disassembling your joint.

Cover oversized holes and the ends of tubes and pipe with these cup-shaped washers.

As you tighten a bolt, these metric washers flatten to add tension to the threaded joint and prevent loosening from small amounts of vibration.

Teeth on the outside edge of these metric washers bite into the screw head and joint for a tight grip.

The teeth on these washers bite further into the screw head and joint than standard external-tooth washers to provide a stronger hold.

To keep 90° countersunk screws from loosening in vibration applications, the teeth on these washers bite further into the screw head and joint than standard external-tooth lock washers for a more secure hold.

Internal teeth dig into the screw head while the smooth outside edge won't snag objects. Use with metric fasteners that have small heads, such as fillister and cheese head screws.

The combination of internal and external teeth boosts gripping power to maintain a tight hold and provide more vibration resistance than other tooth lock washers. Use with fasteners that have heads large enough to make contact with the external teeth, such as pan, button, and binding head screws.

Also known as conical washers, these have a slightly cupped shape that gives them spring-like flexibility to grip tighter than split and tooth lock washers.

Designed for use with square-neck bolts such as carriage bolts, these washers have teeth that dig into wood and other soft material to prevent rotation.

Able to withstand pressure greater than 7,000 psi, these one-piece bonded washers create the tightest seals.

Brass makes these spacers electrically conductive and the zinc-plated finish adds corrosion resistance.

Use these caps to hold components in place and protect shaft ends.

Also known as X-washers, place these rings into the groove and squeeze tight with pliers to form a 360° closure.

SAE washers generally have a smaller ID and OD than USS washers.

USS washers generally have a larger ID and OD than SAE washers.

Teeth bite into the joint for a tighter grip than split lock washers.

With flexible teeth that slide smoothly over threads of any pitch, these push nuts can be used alone for light-duty applications or as a jam nut.

Snap these nuts into square holes in thin materials.

Protect bolts from sideways (shear) pressure.
