An Internally Serrated Lock Washer is a fastener engineered to prevent the unintended loosening of nuts or bolts in applications where vibrations or external forces are present. This type of lock washer distinguishes itself by featuring serrations on its inner surface. When installed, these serrations create a gripping action against the threaded fastener and the mating surface. The serrations bite into the material, generating resistance and effectively preventing the fastener from loosening.

Attributes:
• Create additional resistance against rotation.
• Preventing the fastener from loosening over time.
• Serrations bite into the material, generating resistance
• Creates a gripping action against the threaded fastener and mating surface

Application:
An Internally Serrated Lock Washer is used for resistance to loosening and installing lock washers ensure proper functionality and prevent unintended loosening of fasteners in different equipment applications.
