Spring Lock Washer
The Function of Spring Lock WasherThe lock washer prevents nuts and bolts from turning, slipping and coming loose because of vibration and torque. Different lock washers perform this function in slightly different ways, but the basic concept is to hold the nut and bolt in place. Some lock washers achieve this function by biting into the base material (bolt) and the nut with their ends.
Applications of Spring Lock WasherLock washers are commonly used in applications involving vibration and possible slippage of fasteners. Industries that commonly use lock washers are transportation related (automotive, aircraft, marine). Lock washers may also be used in household appliances such as air handlers and clothes washers (washing machines).
As you tighten a bolt, these metric washers flatten to add tension to the threaded joint and prevent loosening from small amounts of vibration.
Splitlockwashers have a left-hand helix, which means you can only use them with bolts that have right-hand threads to prevent clockwise rotation from vibration. When tightened, their uneven split ends bite into unhardened nuts and bolts for a tighter hold than curved or wave washers, but only for applications with clockwise rotation.
Use zinc-plated washers in mostly dry environments. The zinc plating offers temporary rust protection, but once it wears away the steel will rust. All of these washers are stronger and more wear resistant than stainless steel.
