Lock washers are mechanical fasteners that prevent nuts and bolts from loosening effects caused by vibration. They work by creating friction between the lock washer and the attachment surface. This helps to keep the nut or bolt from turning when vibration occurs during operation. There are three major varieties of lock washer: split-lock, tooth-lock and wave washers.
The most common type of steel lock washer, a split-lock consists of a circular plate with a split in the center. The split allows the lock washer to compress slightly when tightened, creating tension and grip against the fastening surface.
Tooth-lock washers have a series of teeth or ridges that “bite” into the fastening surface. Providing additional grip and resistance to turning, tooth-lock washers are used extensively in automotive, construction and electronics applications.
Wave washers have an undulating, wavy shape that provides a spring effect. When compressed, the shape of the washer creates tension and vibration resistance.
Lock washers are widely used across several industries. Due to their ability to counter vibrations, lock washers are heavily used in applications where movement can disrupt fastenings. Industries that use steel lock washers include:

A lock washer is typically used with fastening hardware such as nuts and bolts. Place the washer on the threaded end of the hardware. Then, screw the nut onto the bolt. Tighten it to create the desired compression and tension.
A steel lock washer creates tension between the fastener and the materials being held together. This tension prevents the hardware from loosening during operation by reducing the impact of vibrations.
