Professional Applications & Engineering Value
This steel split lock washer delivers exceptional engineering value in demanding industrial environments where vibration-induced fastener failure is a critical concern. The standard split lock washer design creates continuous spring tension that compensates for thermal expansion, material settling, and dynamic loads. Manufactured from high-grade steel with precise inch system dimensions (0.385" ID x 0.68" OD), it provides reliable performance in machinery assembly, automotive applications, and heavy equipment maintenance. The Rockwell C38 hardness ensures the washer maintains its locking capability through multiple use cycles, while the ASME B18.21.1 specification guarantees dimensional accuracy and predictable performance across industrial applications requiring 3/8" screw fastening solutions.
Specification Summary & Compliance
This split lock washer features precise dimensional specifications including 0.385" inner diameter, 0.68" outer diameter, and 0.094" thickness, engineered specifically for 3/8" screws. Manufactured to ASME B18.21.1 standards with Rockwell C38 hardness for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance in global industrial markets.
