Product Features


Internal lock washer, also known as a toothed lock washer, is a type of washer that is used to prevent nuts, bolts, and other fasteners from loosening due to vibration or other external forces.


Internal lock washer features a series of teeth or serrations along its inner diameter, which are designed to dig into the mating surface of the nut or bolt head and create a locking effect. This helps to prevent the fastener from turning and loosening, even under conditions of high stress or vibration.


Internal lock washers are commonly made from a variety of materials, including steel, stainless steel, and brass. They are available in a range of sizes and shapes to fit different types of nuts and bolts, and are typically used in applications where a secure and reliable fastening is required.

The teeth of the washer can get into the material of the shaft, so a slight scratch may occur
