Professional Applications & Engineering Value
This heavy-duty split lock washer addresses critical vibration-induced loosening challenges in industrial assemblies. Engineered from zinc yellow-chromate plated steel, it provides dual protection against corrosion while maintaining consistent spring action. The Rockwell C38 hardness ensures the washer maintains its tension and locking capabilities even after repeated compression cycles. Ideal for machinery, heavy equipment, and structural applications where 1 1/8" fasteners require reliable vibration resistance, this washer's standard split lock design creates continuous upward force that counters rotational movement, preventing catastrophic fastener failure in critical assemblies.
Specification Summary & Compliance
This split lock washer features precision dimensions of 1.129" inner diameter, 1.847" outer diameter, and 0.281" thickness, designed specifically for 1 1/8" screw applications. Manufactured to exacting ASME B18.21.1 standards and meeting MS35338-54 specifications, it ensures consistent performance and dimensional accuracy. The zinc yellow-chromate plated steel construction provides superior corrosion resistance while maintaining the required Rockwell C38 hardness for optimal spring performance in demanding industrial environments.
