The zinc plating provides some corrosion resistance.

An economical alternative to standard unthreaded spacers.

Secure computer cables and panels.

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

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

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.

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.

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.

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

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.

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

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.

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

Choose these washers for their adherence to strict military standards for material and construction.

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.

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.

Change thread sizes or types, such as fine to coarse threads, on parts without changing gender.

Change inch threads to metric with these adapters, or swap metric threads for inch. An external hex lets you tighten or loosen them with a wrench.

Increase or decrease metric thread size from one male-threaded part to another. Commonly used to connect two differently sized threaded rods, they have a hex-shaped body, so you can tighten them with a standard wrench.

Adapt threaded rods from inch to metric. These adapters connect two male-threaded fasteners, so you can change the gender of a mating part or increase or decrease its thread size. The hex-shaped body fits into the head of a standard wrench.

Twist these adapters onto female metric threads to change pitch or switch thread sizes.

A zinc-plated finish gives these steel inserts mild 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.

Keep these shaft collars in place by tightening their set screw into the shaft.
