Key Features & Benefits at a Glance
- Superior vibration resistance through conical spring design that maintains constant tension under dynamic loads
- Reliable locking performance with external teeth that bite into mating surfaces to prevent loosening
- Corrosion-resistant construction using stainless steel for extended service life in harsh environments
- Precision dimensional compatibility with 4.325"-12 screw sizes and chamfered bearing nuts for perfect fit
- Industry-standard compliance meeting ANSI/ABMA 8.2 specifications for consistent quality and performance
- Environmental responsibility with RoHS 3 and REACH compliance for safe industrial use
- Optimized load distribution through conical shape that compensates for thermal expansion and settlement
Professional Applications & Engineering Value
This stainless steel spring lock washer delivers critical vibration damping in heavy machinery, construction equipment, and industrial assemblies where constant motion threatens joint integrity. The conical shape with external teeth creates multiple biting points that resist rotational forces, while the spring action maintains clamping force as components settle or expand. Engineered for 4.325"-12 screw sizes and chamfered bearing nuts, it prevents galling and distributes loads evenly across contact surfaces. The ANSI/ABMA 8.2 certification ensures dimensional precision and mechanical properties suitable for high-stress applications in manufacturing, transportation, and energy sectors where failure prevention is paramount.
Specification Summary & Compliance
This spring lock washer features precise dimensions: 4.395" ID, 6.063" OD, 0.401" overall height with 0.132" thickness. Manufactured to ANSI/ABMA 8.2 standards with external tooth configuration and conical shape. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. Designed specifically for 4.325"-12 screw sizes with chamfered bearing nut compatibility.
