Professional Applications & Engineering Value
This split lock washer in zinc-plated steel is engineered to tackle common industrial challenges like vibration-induced fastener failure. Its split design creates constant spring tension, resisting loosening in machinery, automotive, and electrical enclosures where dynamic loads are prevalent. The Rockwell C38 hardness ensures the washer maintains its shape and locking force under repeated stress, while the zinc plating offers a protective barrier against rust and corrosion in humid or outdoor settings. By meeting ASME B18.21.1 specifications, it delivers precise fit and reliable performance for No. 10 screw size applications, reducing maintenance downtime and enhancing operational safety in B2B procurement scenarios.
Specification Summary & Compliance
This washer features an ID of 0.2", OD of 0.294", and thickness of 0.047", designed for No. 10 screw size with standard split lock type. It adheres to ASME B18.21.1 for dimensional and performance standards, ensuring precise thread engagement and vibration resistance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), it meets environmental and safety regulations for industrial use.
