Professional Applications & Engineering Value
These split lock washers are engineered to solve critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and heavy equipment. The zinc-plated steel material provides essential corrosion protection while maintaining the Rockwell C38 hardness necessary for consistent spring action. The precisely calculated split design generates continuous upward force against the fastener, effectively countering rotational forces that cause joint failure. Ideal for 1/4" screw applications in manufacturing, construction, and maintenance operations, these washers deliver reliable locking performance where vibration and dynamic loads compromise standard fastening solutions. The standard split lock washer type ensures easy integration into existing assembly processes without requiring tooling modifications.
Specification Summary & Compliance
This split lock washer features precise dimensions of 0.272" ID, 0.489" OD, and 0.062" thickness, engineered for 1/4" screw size applications. Manufactured to ASME B18.21.1 specifications, these washers guarantee dimensional accuracy and mechanical performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance. The Rockwell C38 hardness rating confirms consistent material properties and reliable spring performance across all production batches.
