Professional Applications & Engineering Value
This steel spring lock washer with external tooth conical design addresses critical vibration-induced loosening in industrial assemblies. The conical spring lock washer geometry creates continuous spring tension that compensates for thermal expansion, material relaxation, and dynamic loads in machinery, automotive, and heavy equipment applications. Engineered specifically for 0.469"-32 screw fastening systems, the external tooth configuration provides maximum bite into mating surfaces while the chamfered bearing nut face style facilitates smooth installation without damaging components. Manufactured to ANSI/ABMA 8.2 standards, this inch system washer delivers predictable performance in high-vibration environments where fastener security is paramount.
Specification Summary & Compliance
This spring lock washer features precision dimensions including 0.484" ID, 1.016" OD, and 0.046" thickness with external tooth location. Manufactured in compliance with ANSI/ABMA 8.2 specifications for dimensional accuracy and performance requirements. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) environmental standards, ensuring suitability for regulated industrial applications worldwide. Designed specifically for use with 0.469"-32 screws and chamfered bearing nut face configurations.
