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.

These washers have smaller outside diameters than standard spring lock washers to fit neatly under socket head cap screws.

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.

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.

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

Plastic washers are good electrical insulators.

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