      What Is an Internal Tooth Lockwasher?

      Internal tooth lockwashers are much like traditional washers, but include teeth that ring the inside portion. These teeth are used to sink down into the bearing surface and provide greater stability. Fasteners can loosen over time, especially in applications that include impact, motion or vibration. The teeth of the lockwasher help prevent slippage and loosening.

      Applications of Internal Lockwashers

      Lockwashers are typically used when vibration will threaten the stability of fasteners. For example, when inserting fasteners into factory equipment, the motion of the machines can force those fasteners to loosen. With an internal tooth lockwasher, the added stability can prevent vibration-related slippage from occurring.

      A Variety of Washer Materials and Finishes

      Whatever your application, you need fasteners that fight back against corrosion. Internal tooth lockwashers are available in a number of materials and finishes to provide corrosion-resistance performance, including zinc, yellow zinc, black zinc, black oxide, stainless steel and more. Choose the finish that best meets your needs for both performance and aesthetics.
