Professional Applications & Engineering Value
This zinc-plated steel split lock washer delivers critical vibration resistance in demanding industrial environments where fastener security is paramount. The standard split lock washer design creates continuous spring tension that compensates for thermal expansion, material settling, and dynamic loads. Engineered specifically for 2" screw applications, the washer's precise internal diameter ensures secure seating while the Rockwell C38 hardness maintains structural integrity under repeated stress cycles. The zinc plating provides essential corrosion protection in manufacturing facilities, construction sites, and heavy equipment applications where exposure to moisture and environmental elements is common. This industrial-grade fastener solves the critical challenge of maintaining assembly reliability in vibrating machinery, transportation equipment, and structural frameworks where loosening fasteners could lead to equipment failure or safety hazards.
Specification Summary & Compliance
This split lock washer features precise dimensions with 2.039" internal diameter, 2.936" outer diameter, and 0.422" thickness, manufactured to ASME B18.21.1 standards for dimensional accuracy and performance reliability. The product maintains Rockwell C38 hardness throughout its zinc-plated steel construction and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring strict material compliance.
