Professional Applications & Engineering Value
This zinc-plated steel split lock washer delivers critical vibration resistance in demanding mechanical assemblies where fastener security is paramount. The Rockwell C38 hardness maintains spring tension under continuous stress, preventing joint failure in heavy machinery, automotive systems, and industrial equipment. The standard split lock design creates constant upward force against the bolt head or nut, effectively countering rotational loosening caused by vibration and thermal cycling. Engineered to ASME B18.21.1 specifications, this 1" split lock washer provides reliable performance in inch-system applications across manufacturing, construction, and maintenance operations where consistent locking action is essential for operational safety and reduced maintenance intervals.
Specification Summary & Compliance
This split lock washer features precise dimensions (1.024" ID, 1.478" OD, 0.25" thickness) manufactured to ASME B18.21.1 standards for dimensional accuracy and performance reliability. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. The Rockwell C38 hardness specification guarantees consistent mechanical properties and spring performance in accordance with industry standards for locking washers.
