Professional Applications & Engineering Value

This heavy-duty split lock washer addresses the critical challenge of fastener loosening in high-vibration environments. The zinc-plated steel construction combined with the standard split lock design creates a reliable spring action that maintains constant pressure against both the fastener and mounting surface. This engineering solution is particularly valuable in industrial applications such as machinery assembly, automotive systems, and heavy equipment where vibration resistance is paramount. The Rockwell C38 hardness ensures the washer maintains its structural integrity and locking capability through thermal expansion cycles and mechanical stress, providing long-term reliability in demanding operating conditions while meeting rigorous ASME B18.21.1 standards for consistent performance.

Specification Summary & Compliance

This split lock washer features precise dimensional specifications with 1.024" inner diameter, 1.656" outer diameter, and 0.25" thickness, engineered for 1" fasteners. Manufactured to ASME B18.21.1 standards, it ensures consistent quality and performance in inch system applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental and safety requirements for industrial components.
