A lock washer is a type of washer used in mechanical assemblies to prevent fasteners, such as bolts or screws, from loosening due to vibration or other forces. Lock washers have teeth or ridges on their surface that grip the material they are placed against, such as a nut or bolt head, and prevent it from rotating or backing out of the assembly.
There are several types of lock washers, including split washers, toothed washers, and star washers. Split washers are the most common type and are characterized by a split or cut along the circumference of the washer, creating two prongs that can compress and grip the fastener. Toothed washers have teeth that dig into the material and create friction to prevent loosening. Star washers have teeth that are shaped like stars and offer a high degree of locking force.
Lock washers are commonly used in automotive, aerospace, and industrial applications where vibration is a concern. However, their effectiveness in preventing loosening is often debated, and some experts recommend using other types of fasteners, such as thread-locking compounds, for more reliable and consistent results.
