Use these metric washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.

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.

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

When you’ve applied the correct tension, these washers release an orange dye as a visual indicator.

Flat and oval head screws sit flush within these metric washers for a neat, finished appearance.

With greater diameters and/or thicknesses than general purpose washers, these washers cover oversized holes or act as spacers and levelers. Clipped to fit where standard washers can’t, they won’t rotate when you position the flat edge against a flat surface.

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

Use the angled edges to hold and align tie-down straps.

As a screw is tightened, these washers flatten to add tension to the joint and prevent loosening from small amounts of vibration.

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.

The arched shape of these washers presses up against a bolt and down against a nut to prevent loosening from wear, vibration, or temperature changes.

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.

The teeth on these washers firmly grip heads of 82° flat head countersunk screws.

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.

Able to withstand pressure greater than 3,000 psi, these one-piece bonded washers create the tightest seals.

The zinc plating provides some corrosion resistance.

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

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

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

No groove required—press these rings onto the end of a shaft for a firm grip.

A flange distributes the load over a large area and reduces stress where the nut meets the material surface.

These metric push nuts can be used as a standalone for light-duty applications or as a jam nut.

Press these rounded head nuts into a closed-end hole or thick panel in applications where the back of the panel is inaccessible. A quarter-turn locks and releases access panels, doors, and covers.

Press these rounded head nuts into the backside of a panel in applications where you have access to both sides of the panel. A quarter-turn locks and releases access panels, doors, and covers.

These wing-head screws have a clip-on nut that allows you to mount them near the edge of a thin panel. Use them to lock and release access panels, doors, and covers with a quarter-turn.

These rounded head nuts can be riveted into thin panels for a flush fit. They can be mounted without spaces between the panels. A quarter-turn locks and releases access panels, doors, and covers.

A zinc-plated finish gives these steel inserts mild corrosion resistance.

Use with hex nuts to connect threaded rod.

Keep hardware centered in the strut channel slot.
