Lock Washers

Lock Washers are essential components in many mechanical and structural applications, serving to prevent nuts and bolts from loosening due to vibration and torque. A lock washer, also known as a locking washer, is specifically engineered to provide tension and friction between the fastener and the surface it's clamping, ensuring a secure and lasting connection. This is particularly crucial for machinery that is subjected to constant movement and stress.

The most common type is the split lock washer or split washer, which has a single coil design with an open end. When the nut is tightened, the split ends are flattened, creating a spring-like force that presses against the nut and the mating surface. This locking action helps maintain the torque and prevents the fastener from backing out. The proper lock washer placement is vital for its effectiveness; it should be placed under the nut or under the screw head to create the necessary tension. Metal washer options are available in various materials, including steel, stainless steel, and brass, to suit different environmental and strength requirements.
