Internal Tooth Shakeproof Washers Zinc Plated - 100 Pack

Internal Tooth Shakeproof Washers, zinc-plated, are designed with serrated teeth on the inner edge that bite into the mating surface to prevent loosening of fasteners under vibration or torque. The zinc plating offers corrosion resistance, making these washers suitable for use in both indoor and outdoor environments. They are commonly used in automotive, industrial, and machinery applications where a secure and lasting grip is essential. The internal teeth ensure that the washer stays fixed in place while the fastener tightens, providing enhanced stability to the assembly.
