About Washers

External-Tooth Lock Washers

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

Metric External-Tooth Lock Washers

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

Mil. Spec. External-Tooth Lock Washers

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

Tight-Grip External-Tooth Lock Washers

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

Countersunk External-Tooth Lock Washers

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

Countersunk Tight-Grip External-Tooth Lock Washers

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-Tooth Lock Washers

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

Metric Internal-Tooth Lock Washers

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.

Mil. Spec. Internal-Tooth Lock Washers

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

Internal-Tooth Lock Washers for Soft Material

Slightly domed with an oversized outside diameter, these washers distribute your fastener's load over a larger surface area than other internal-tooth lock washers to limit damage to soft material.

Internal-/External-Tooth Lock Washers

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.

Tooth Lock Washer Assortments

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