Regular Split Lock Washer Clear Zinc Cr3 Plating

Regular Split Lock Washer with Clear Zinc Cr3 Plating – Reliable Locking with Clean Corrosion Protection

When your fastening system requires dependable vibration resistance and added corrosion protection, the regular split lock washer with Clear Zinc Cr3 plating delivers consistent, cost-effective performance. Combining classic helical spring tension with a modern, environmentally compliant finish, these washers are ideal for automotive, electrical, HVAC, and light industrial applications.

Proven Locking Action for Secure Assemblies

Helical Split Design

The traditional split lock (helical) design creates continuous spring tension between the nut or bolt head and the mating surface. As the fastener is tightened, the washer compresses and exerts outward force, helping resist loosening caused by vibration, dynamic loads, or thermal expansion. This mechanical locking action makes split lock washers a trusted solution for maintaining clamp load in bolted connections.

Durable Steel Construction

Manufactured from heat-treated medium carbon steel, these washers are engineered to withstand moderate torque without deforming. Their strength and resilience make them compatible with Grade 2, Grade 5, and Grade 8 bolts and nuts, ensuring dependable performance across a wide range of assemblies.

Clear Zinc Cr3 Plating – Modern Corrosion Resistance

The Clear Zinc Cr3 (trivalent chromate) finish provides a bright, silver appearance along with moderate corrosion resistance. Unlike older hexavalent chromium (Cr6) coatings, Cr3 plating is RoHS and REACH compliant, making it a safer and more environmentally responsible choice. This finish protects against rust in indoor and lightly exposed outdoor environments while maintaining a clean, professional look.
