Create more tension than split lock washers for a tighter hold on materials that contract and expand

Grip flat- and oval-head screws for a secure hold without overtightening

A step up from flat washers, these stop nuts and screws from loosening due to slight movement

Spread pressure over a large area to limit damage to material

The tightest grip of all our washers for use on equipment with jarring starts and stops

Won't loosen on equipment with constant, vigorous vibration; also known as Belleville washers

Fit neatly under screws with narrow heads; also known as Belleville washers

Adhere to U.S. military standards for material and construction

A collection of common sizes to fit the broadest range of applications

Stop nuts and screws from loosening due to light vibration

Fit neatly under screws with narrow heads

Bend the tabs up or down to resist loosening from moderate vibration, such as pumps

Keep a collection of tooth lock washers on hand to work with a range of screw sizes

Grip tighter than split lock washers in applications with constant movement, such as conveyors

Keep bolted assemblies secure on slightly uneven surfaces
