Professional Applications & Engineering Value
These split lock washers deliver critical vibration-damping performance in demanding industrial settings where fastener security is paramount. The Black-Oxide 18-8 Stainless Steel construction provides excellent corrosion resistance while maintaining the material's inherent strength, making these washers ideal for outdoor equipment, marine applications, and chemical processing environments. The standard split lock design creates constant upward pressure against the fastener head or nut, effectively preventing rotation and maintaining clamp load despite continuous vibration and thermal cycling. With Rockwell C35 hardness, these washers maintain their spring properties through repeated compression cycles, ensuring long-term reliability in machinery, automotive assemblies, and structural applications where 1/4" screw fastening requires dependable locking performance.
Specification Summary & Compliance
This split lock washer features precise dimensions of 0.26" ID x 0.363" OD with 0.078" thickness, manufactured to ASME B18.21.1 standards for dimensional consistency and performance reliability. The product maintains compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence. Designed specifically for 1/4" screw applications within the inch measurement system, these washers deliver consistent locking performance while meeting industry specifications for material quality and manufacturing precision.
