Professional Applications & Engineering Value
This heavy-duty split lock washer addresses critical vibration-induced loosening challenges in industrial machinery, construction equipment, and heavy mechanical assemblies. The steel construction with Rockwell C38 hardness maintains its spring properties under continuous load, while the standard split lock design creates consistent radial pressure against both the fastener and bearing surface. The precise 2.039" ID ensures proper fitment on 2" screws, preventing misalignment in critical connections. Engineered for applications where thermal cycling and mechanical stress compromise fastener integrity, this vibration resistant washer provides reliable locking performance in automotive, manufacturing, and infrastructure projects where safety and reliability are paramount.
Specification Summary & Compliance
This split lock washer features dimensional specifications of 2.039" ID × 2.936" OD × 0.422" thickness, manufactured to ASME B18.21.1 standards for consistent performance and interchangeability. The washer demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety in industrial applications. Manufactured in the inch system with precise tolerances, this standard split lock washer type delivers reliable locking action for 2" screw applications across various industrial sectors.
