Lock Washers

Lock Washers

Lock washers are mechanical components used to prevent threaded fasteners from loosening due to vibration, thermal expansion, or other factors. They are typically made of metal, and come in a variety of shapes and sizes depending on the application. Lock washers work by creating friction between the fastener and the surface it is being tightened against, which helps to keep the fastener in place. One common type of lock washer is the split washer, which has a split in the center that allows it to compress slightly when tightened. This compression creates a spring-like effect, which helps to keep the fastener in place. Another type of lock washer is the toothed washer, which has teeth around the outer edge that bite into the surface it is being tightened against. This creates a locking effect that helps to prevent the fastener from loosening. Lock washers are commonly used in automotive, aerospace, and industrial applications, where vibration and other factors can cause threaded fasteners to come loose. They are often used in conjunction with other fastening methods, such as thread-locking compounds or safety wire, to provide additional security.
