Serrated Lock Washer

A serrated lock washer, also known as a shakeproof washer or toothed washer, is a type of washer designed to prevent loosening of nuts, bolts, screws, and other fasteners. It is characterized by the presence of serrations or teeth on one side of the washer. These serrations bite into the mating surfaces, creating friction and resistance to rotation.

Product Feature

Serrated lock washers are commonly used in various industries, such as automotive, construction, and machinery, where vibration and movement can lead to the unintentional loosening of fasteners.The primary purpose of a serrated lock washer is to resist loosening caused by vibrations or other external forces. The teeth on the washer dig into the material, providing a form of resistance that helps maintain the tightness of the fastener.These washers are typically made from materials like steel or stainless steel, providing strength and corrosion resistance.The serrated side of the washer is placed against the mating surface, with the teeth facing the surface. When the nut or bolt is tightened, the serrations create indentations in the material, enhancing the grip and reducing the likelihood of rotation.Serrated lock washers come in different types, including internal tooth lock washers and external tooth lock washers. Internal tooth lock washers have teeth on the inner circumference, while external tooth lock washers have teeth on the outer circumference.
