Designed for use with bearing nuts, these lock washers have a conical shape that presses like a spring against bearings, bushings, gears, and pulleys to hold them in place on your threaded shaft or spindle.

Bend the tab of these metric lock washers against the flats of a hex nut or bolt head to prevent the fastener and washer from turning and loosening due to vibration, wear, or changes in temperature.

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.

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.

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.

Repair sagging, cracked plaster with these washers. The holes allow plaster to flow through to form a secure bond between the washer and the wall.

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