Professional Applications & Engineering Value
This split lock washer is engineered to solve critical vibration-induced loosening in industrial machinery, automotive systems, and heavy equipment. Made from zinc-flake-coated steel, it combats corrosion while maintaining Rockwell C38 hardness to withstand repetitive stress cycles. The standard split lock washer type applies continuous tension, biting into mating surfaces to prevent back-off, making it ideal for No. 10 screw applications in engines, conveyors, and structural frames. By adhering to ASME B18.21.1, it ensures dimensional accuracy and reliable performance, reducing maintenance downtime and enhancing safety in demanding industrial fastening scenarios.
Specification Summary & Compliance
This washer features precise inch-system dimensions: 0.2" inner diameter, 0.334" outer diameter, and 0.047" thickness, designed for No. 10 screw sizes. It conforms to ASME B18.21.1 specifications for standard split lock washers, ensuring consistent thread engagement and spring performance. The zinc-flake coating provides RoHS and REACH compliance for environmental safety, while the material and hardness meet industrial requirements for reliable, long-term use in mechanical assemblies.
