Thru-Hardened Heavy Split Lock Washer with Yellow Zinc Cr6 Plating – High Strength Meets Long-Lasting Corrosion Protection

When you need superior locking power and corrosion resistance in one dependable component, look no further than the thru-hardened heavy split lock washer with Yellow Zinc Cr6 plating. Designed for demanding applications involving high torque, intense vibration, and exposure to harsh environments, this washer is a trusted choice in construction, heavy equipment, and structural assemblies.

Manufactured from medium carbon steel, each washer undergoes a thru-hardening heat treatment process—ensuring full-depth strength and resistance to crushing and fatigue. Unlike case-hardened or standard split washers, these thru-hardened heavy-duty washers provide the mechanical muscle to hold up under extreme pressures and maintain joint integrity even in the toughest conditions.

The Yellow Zinc Cr6 finish adds both form and function. It not only gives the washer a distinctive golden hue but also provides excellent corrosion resistance, making it ideal for indoor and moderately corrosive outdoor environments. The Cr6 chromate layer creates a durable protective coating that extends service life and complements matching plated fasteners.
