DIN 125A 140HV Metric Flat Washer with Clear Cr3 Zinc Plating

DIN 125A 140HV Metric Flat Washer with Clear Cr3 Zinc Plating

DIN 125A 140HV metric flat washers with Clear Cr3 zinc plating are engineered for superior performance in fastening applications where corrosion resistance, strength, and reliability are critical. Manufactured to DIN 125A standards, these washers are designed to evenly distribute load, protect mating surfaces, and enhance the overall integrity of bolted assemblies in industrial and commercial environments.

140HV Hardened Steel for High Load Capacity

The 140HV hardness rating indicates a heat-treated washer capable of withstanding high compressive forces without deformation. This makes DIN 125A washers an excellent choice for use with high-strength metric bolts, including Class 8.8, 10.9, and 12.9 fasteners. Their hardened construction ensures consistent performance in applications subject to vibration, torque, and heavy clamping loads.

Clear Cr3 Zinc Plating for Corrosion Resistance

Clear Cr3 (trivalent chromium) zinc plating provides a durable, environmentally compliant protective coating that resists rust and oxidation. Unlike traditional hexavalent chromium coatings, Cr3 plating meets RoHS compliance standards, making it a safer and more sustainable option. This finish offers a clean, bright appearance while delivering dependable corrosion protection for indoor and light outdoor use.
