Tooth Lock Washers

Grip tighter than split lock washers to prevent nuts and screws from loosening in applications with constant movement, such as conveyors. Tooth lock washers typically can't be reused because the teeth often get bent when tightened.

External Tooth

Teeth on the outside edge bite into both the fastener and the mating surface for a stronger hold than internal-tooth lock washers. However, they may mar your material and snag on objects. Pair these washers with nuts and screws that are large enough to make contact with the teeth, such as pan, button, and binding head screws.

18-8 Stainless Steel—The choice for wet and outdoor environments, these washers won't rust when exposed to moisture. However, they can't hold up to the harsh chemicals that 316 stainless steel can.

Black-Oxide 18-8 Stainless Steel—Typically chosen for their appearance, these washers have a dark, matte coating to create a finished look. They won't rust in wet and outdoor environments, but can't hold up to harsh chemicals as well as 316 stainless steel.

Highly-Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these washers won't degrade when exposed to harsh weather, salt water, and most chemicals.

Wear-Resistant 400 Series Stainless Steel—These grip hard material better than other types of stainless steel. They are not as corrosion resistant as 18-8 and 316 stainless steel, so they are best for environments that experience occasional moisture.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Black-Oxide Steel—Typically chosen for their appearance, these washers have a dark, matte coating that creates a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

Highly-Corrosion-Resistant Phosphor Bronze—Stronger and more wear resistant than silicon bronze, but with the same excellent corrosion resistance. These washers won't rust or deteriorate when submerged in salt water, so they're a good fit for marine environments.

DIN 6798—Best for slightly bumpy or irregular surfaces because the teeth are angled to make even contact with the material.

Internal and External Tooth

The strongest hold of all our tooth lock washers, these combine internal and external teeth to boost gripping power. However, the teeth may mar your material and snag on objects. Pair these washers with fasteners that are large enough to make contact with the external teeth, such as pan, button, and binding head screws.

Wear-Resistant 410 Stainless Steel—These grip hard material better than other types of stainless steel. They are not as corrosion resistant as 18-8 and 316 stainless steel, so they are best for environments that experience occasional moisture.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Bearing Spring Lock Washers for Slotted Bearing Nuts


	For Chamfered Nuts

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. They also have an inner tab that sits in the shaft or spindle’s keyway to prevent the nut from loosening.

Steel—Steel washers are strong and flexible.

Stainless Steel—Stainless steel washers are more corrosion and chemical resistant than steel washers.

External Tooth—Washers with external teeth grip components using their teeth, in addition to spring tension.

DIN 5406—DIN 462 and DIN 5406 washers meet international standards for lock washer dimensions. Pair DIN 462 washers with DIN 1804 bearing nuts, and DIN 5406 washers with DIN 981 bearing nuts.

Countersunk Tooth Lock Washers

These washers grip flat- and oval-head countersunk screws, so you get a secure hold without overtightening. They resist loosening in applications with constant motion, such as conveyors. Tooth lock washers typically can't be reused because the teeth often get bent when tightened.

External Tooth

Teeth on the outside edge bite into both the screw head and the mating surface to lock the assembly in place.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

DIN 6798—Best for slightly bumpy or irregular surfaces because the teeth are angled to make even contact with the material.

Mil. Spec. Tooth Lock Washers

These washers are manufactured and tested to strict U.S. military standards for material and construction. They resist vibration better than split lock washers to prevent nuts and screws from loosening in applications with constant movement, such as conveyors. Tooth lock washers typically can't be reused because the teeth often get bent when tightened.

Tooth Lock Washer Assortments

Keep a collection of tooth lock washers on hand to work with a range of screw sizes. The teeth bite into material to prevent fasteners from loosening in applications with constant movement, such as conveyors. External-tooth lock washers grip tighter than internal-tooth lock washers, however, they may mar your material and snag on objects. Tooth lock washers typically can't be reused because the teeth often get bent when tightened.

Labels in the lid include our part numbers, so it's easy to replenish the assortments.
