#10 Hi-Collar Split Lock Washer - .2/.193" I.D. - .047" Thick - Steel - Plain - Grade 2 - Pkg of 100

External Tooth Lock Washers 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. Hardware is constructed of high quality steel for long lasting durability.

Internal Tooth Lock Washers lock into bolt head or nut to prevent backoff rotation, which works best with smaller head screws, such as fillister heads. Hardware is constructed of high quality steel for long lasting durability.

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.

Split Lock Washers are manufactured with a trapezoidal cross section that deflects under load and can be used with or without a Hardened Flat Washer. They provide marginal resistance to vibration loosening and are ideal in applications where fasteners have a tendency to rotate or lose friction. Split Lock Washers are forged from hardened steel and zinc coated. They are covered by ASME B18.21.1. Special Features: Trapezodial Cross Section, Vibration Resistance Applications: General Purpose
