DIN127B-YZP Yellow Zinc Plated 70# Carbon Steel Helical Spring Split Lock Washer

DIN127B-YZP Yellow Zinc Plated 70# Carbon Steel Helical Spring Split Lock Washer. Made from 70# high-carbon spring steel, this DIN127B washer offers excellent elastic recovery and fatigue resistance, preventing bolt loosening under vibration. The yellow zinc plating provides reliable corrosion protection for indoor or light outdoor use, while the bright color enables fast visual inspection on assembly lines. Engineered to DIN127B, the helical split edge digs into both the bolt thread and mounting surface, delivering consistent prevailing torque against shock and movement. Available from M3 to M20, this series suits applications from precision electronics to heavy machinery, ideal for inventory stocking and project sourcing.
