Professional Applications & Engineering Value
Engineered for demanding industrial applications, these K500 Nickel split lock washers deliver exceptional performance in high-vibration environments where fastener security is critical. The split lock washer design creates continuous spring tension that compensates for thermal expansion, material relaxation, and mechanical vibrations. Made from K500 Nickel alloy, these washers maintain their mechanical properties in corrosive conditions, making them ideal for chemical processing, marine equipment, and aerospace applications. The precise 1/4" internal diameter ensures perfect fitment while the ASME B18.21.1 standard compliance guarantees consistent quality and performance across your fastener assemblies. These industrial washers effectively prevent loosening in machinery, electrical enclosures, and structural connections where vibration-induced failure is a concern.
