Heavy-Vibration-Resistant Spring Lock Washers

With a grip that's second only to wedge lock, these washers stop nuts and screws from wiggling loose under constant, vigorous vibration. They are ideal for engines, turbines, generators, and other heavy duty equipment. Similar to a spring, they flatten under pressure to add tension between mating surfaces. As long as the washers aren't deformed or otherwise damaged, you can reuse them indefinitely without losing locking strength. Also known as conical washers and Belleville washers.

Stack multiple washers in the same direction to double or triple how much weight they can bear. Stack washers in opposite directions for better deflection, which means they compress further and withstand more shock and movement without loosening.

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.

High-Strength 17-7 PH Stainless Steel—The strongest stainless steel washers we offer, these are comparable to high-strength Grade 8 steel. They won’t rust in wet and outdoor environments, but they can’t handle the harsh chemicals that 316 stainless steel can.

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

Phosphate-Coated Steel—Paint adheres evenly to the surface of these washers, so you can add your own decorative finish. They are more durable than zinc-plated steel washers to withstand wet and outdoor environments. However, they won't hold up to the harsh chemicals that stainless steel can.

Steel—Best for dry environments since moisture will cause these washers to rust.

Acetal—Lightweight, nonconductive, and naturally rust resistant. These washers won't swell or lose their strength if exposed to moisture.

Top Serration—Adds friction for extra gripping power.

DIN 432—These washers have a small tab that presses up against the flats of your nut or screw for extra security.

Extreme-Vibration-Resistant Wedge Lock Washers

Image of Product. Bottom orientation. Lock Washers. Wedge-Lock Washer.

When it's critical to keep bolted assemblies secure, choose these two-piece lock washers with the tightest grip of all. They stop nuts and screws from loosening in heavy machinery that experiences jarring starts and stops, such as compressors and compactors. Serrations on the outside bite into the fastener and mating surfaces, while wedges on the inside lock the two pieces together. When the nut or screw starts to loosen, the wedges drive more tightly together to maintain tension. You can reuse these washers up to fifteen times, as long as the serrations and wedges are not worn down. They are comparable to NORD-LOCK® or Sherex TEC® washers.

Spring/Wedge Lock

More flexible than standard wedge lock washers to withstand stronger shocks and vibration. They have a cone shape that expands and compresses to maintain tension in the joint, similar to a heavy duty spring.

Highly Corrosion-Resistant Zinc-Flake-Coated Steel—With 40 times the corrosion resistance of zinc-plated steel, these withstand rust as well as 316 stainless steel. They have been tested to extreme standards, including 1,000 hours of salt spray. They are similar to Magni-coated washers.

Heavy-Vibration-Resistant Spring Lock Washers for Socket Head Screws

Stop socket head screws from wiggling loose on equipment with constant, vigorous vibration, such as engines, turbines, and generators. These washers have a small diameter to fit under screws with narrow heads. Similar to a spring, they flatten under pressure to add tension between mating surfaces. As long as the washers aren't deformed or otherwise damaged, you can reuse them indefinitely without losing locking strength. Also known as conical washers and Belleville washers.

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

Steel—Best for dry environments since moisture will cause these washers to rust.

Top-and-Bottom Serration—Adds friction for extra gripping power.

Bearing Spring Lock Washers for Slotted Bearing 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 462 and 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.

Tab Lock Washers

1 Tab

Instead of relying on friction, these washers lock mechanically for more holding power than split and tooth lock washers. Bend the tabs with a wrench to stop both the fastener and washer from rotating. They are often used in applications with moderate vibration, such as motors, mixers, and pumps. These washers are not reusable because the tabs will weaken if you bend them repeatedly.

1 Tab—Bend the tab down over the edge of your mounting surface, and bend the side of the washer up against the nut or screw.
