How Nord-Lock Washers Work

Machine vibrations are often enough to loosen bolts. Lock washers work as fasteners to keep the bolts on tight. What follows is a bit of explanation on how these washers work and why you’ll want to invest in excellent ones.

What are lock washers?

There are different types of washers, used in a variety of applications. However, lock washers work as locking devices, Engineer Dog says. These washers are designed to keep the bolts and nuts in your systems from coming loose. Some have rings with uneven ends and others are shaped like a star, with teeth on the outer ring.

How do the washers work?

Adding the lock washer keeps the bolts from turning and slipping. Without the lock washer to keep the bolts or nuts in place, machine vibrations will be enough to get the bolts to turn loose eventually. Some lock washers bite into the base materials with their ends to keep the nuts and bolts from coming apart. That’s the design that Nord-Lock washers have.

Are there different types of lock washers?

Before you shop, you’ll need to explore different types of lock washers. A helical lock washer, which is also termed a split washer, looks like a ring, but one that comes with uneven ends. The ends bite into the fastener material, which keeps the nuts and bolts from turning. Internal-tooth lock washers, on the other hand, have teeth on the inside of the ring, which makes it possible to connect with small fastener heads, the Hunker explains. There are also external-tooth lock washers, which are also known as star washers. You can find teeth on the outside ring of these washers, a feature that makes these locking components ideal for large fastener heads. For projects that use high-tightening torques, pyramidal-type lock washers are the way to go. Other types of lock washers include dome-type lock washers capable of distributing a load over a wide area and dish lock washers used for applications that use less torque or load.

What applications require washers?
Applications that involve vibration and possible slippage of fasteners require washers. Industries such as the aircraft, marine, and automotive industries all use washers. Household appliances, too, require washers such as air handlers, clothes washers for washing machines and more. If your project involves any of these, then you need to invest in quality washers.

What should I know?
Washers can lose their locking ability when too much torque or pressure is applied to the washer. If the pressure flattens the washer, that dramatically reduces its function as a locking mechanism. To prevent problems, make sure you don’t use washers with bolts or nuts that are too long. Otherwise, that may compromise the washer’s locking capability.

If you are shopping for lock washers, take a look at trusted brands and designs. Pick out options like nord lock washers for excellent results. Don’t forget to check out reliable shops for your washers. Browse through consumer reviews about the shop and its products to help you decide if you’ve found one you can trust.
