Product Details
Combination internal/external tooth lock washers provide dual benefits. The internal teeth lock into bolt heads or nuts to prevent backoff rotation, which works best with smaller head screws, such as fillister heads. The external teeth secure bolt heads or nuts to increase the bearing area and offer greater hardness so that the nut or bolt can be rotated without distortion of the bearing surface. These washers are designed with specific dimensions and specifications that enhance their performance and reliability in securing fasteners in various applications.
