Professional Applications & Engineering Value
This heavy-duty split lock washer addresses critical vibration-induced loosening in industrial assemblies where mechanical stability is paramount. Engineered from zinc-plated steel with Rockwell C38 hardness, the washer maintains consistent spring tension under dynamic loads, making it ideal for machinery, automotive, and construction applications. The standard split lock washer type creates continuous upward force against the bolt head and downward force against the bearing surface, effectively resisting rotational movement. With precise 0.45" ID dimensions specifically designed for 7/16" screws, this fastener ensures secure fitting in high-vibration environments while the zinc plating provides essential corrosion resistance for extended operational life in demanding conditions.
Specification Summary & Compliance
This split lock washer features precise dimensional specifications including 0.45" inner diameter, 0.776" outer diameter, and 0.109" thickness. Manufactured to ASME B18.21.1 standards for dimensional accuracy and performance requirements, it demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The Rockwell C38 hardness ensures consistent mechanical properties and reliable spring action in industrial fastening applications.
