External Tooth Lock Washers, M4, Carbon Steel, Zinc Plated, Pkg Qty 100
These external tooth lock washers are engineered to prevent fastener loosening under vibration and dynamic loads. Manufactured from 65Mn carbon steel and heat-treated to a 400 HV hardness, they provide reliable, high-strength locking performance. The zinc plating offers corrosion resistance for extended service life. Designed for use with M4 fasteners, the external teeth bite into both the bearing surface and the fastener head to maintain secure clamping force.
