Professional Applications & Engineering Value
This steel split lock washer delivers critical vibration resistance in demanding industrial applications where mechanical stability is paramount. The precisely engineered split lock washer type creates constant spring force that compensates for thermal expansion, material relaxation, and dynamic loads. Engineered to ASME B18.21.1 standards with Rockwell C38 hardness, this washer maintains its locking capability through repeated stress cycles in machinery, automotive assemblies, and electrical enclosures. The 0.133" ID specifically accommodates No. 5 screw size applications, providing reliable fastening security in inch-based manufacturing environments where vibration-induced failure is a constant concern.
Specification Summary & Compliance
This standard split lock washer features precise dimensional specifications: 0.133" inner diameter, 0.236" outer diameter, and 0.031" thickness. Manufactured to ASME B18.21.1 specifications for dimensional accuracy and performance requirements. The washer demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial supply chains. The Rockwell C38 hardness rating confirms consistent material properties and reliable performance across all production batches.
