Enhance the security of your fasteners with Internal Tooth Zinc Lock Washers from Fasteners & Fittings. These washers feature internal teeth that bite into the surface of the fastener and the material being fastened, providing a strong grip that prevents loosening due to vibration or movement. The zinc plating adds corrosion resistance, making them ideal for both indoor and light outdoor applications.

The internal teeth ensure a clean, discreet finish while maintaining a secure, tight hold. These lock washers are perfect for applications that require additional fastening security, such as in electrical, automotive, and mechanical projects.
