Belleville Spring Lock Washers for Socket Head Screws

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

Metric Spring 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.

Metric Tab Lock Washers

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.
