Professional Applications & Engineering Value
This zinc-plated steel spring lock washer is engineered to solve critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and heavy equipment applications. The Rockwell C40 hardness ensures the washer maintains its spring tension under extreme operational stresses, while the zinc plating provides essential corrosion resistance in harsh environments. The precise 1.28" ID and 2.75" OD dimensions combined with the controlled 0.200-0.222" thickness create optimal spring action that compensates for thermal expansion, material settling, and dynamic loads. This heavy-duty lock washer delivers reliable performance in critical fastening joints where vibration resistance is paramount for operational safety and maintenance reduction.
Specification Summary & Compliance
Manufactured to inch system standards with precise dimensional tolerances, this spring lock washer features a 1.28" inner diameter and 2.75" outer diameter with thickness ranging from 0.200" to 0.222". The component is certified RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant as of June 14, 2023, meeting the latest environmental and safety regulations for industrial components. Designed specifically for 1 1/4" screw size applications, it maintains Rockwell C40 hardness throughout its service life for consistent mechanical performance.
