A Comprehensive Guide to Split Lock Washers

Split lock washers are essential mechanical components used primarily to prevent the loosening of fasteners due to vibrations or dynamic loads. These washers play a vital role in ensuring the integrity and stability of connections in various applications, from machinery to automotive assemblies. This article explores the technical features, types, and applications of split lock washers, highlighting key manufacturers and suppliers in China, including www.techstamping.com, www.shanghaimetal.com, www.fastenersco.com, and www.hydgetpower.com.

Understanding Split Lock Washers

A split lock washer, also known as a helical spring washer, features a split design that creates a spring effect. When installed between a nut and a surface, it exerts tension, thereby increasing friction and preventing the nut from loosening. This mechanism is particularly useful in environments where vibrations are prevalent.
