Professional Applications & Engineering Value
This Grade 8 heavy-duty locknut with center lock distorted thread technology provides critical vibration resistance in demanding industrial applications. The zinc-flake-coated steel construction delivers superior corrosion protection, making it ideal for outdoor equipment, machinery, and automotive assemblies exposed to harsh environments. The 3/8"-16 UNC coarse thread with Class 2B fit ensures reliable engagement and consistent performance in high-vibration scenarios where standard nuts would fail. Engineered for heavy-duty industrial locknut applications, this fastener maintains clamping force under extreme conditions, reducing maintenance frequency and preventing equipment downtime in manufacturing, construction, and transportation sectors.
Specification Summary & Compliance
This distorted thread locknut features precise Class 2B thread fit with UNC 3/8"-16 coarse threading and right-hand direction. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) standards, ensuring environmental compliance. The external hex drive (9/16" width) and 21/64" height provide standard tool compatibility. Grade 8 strength classification guarantees consistent performance in industrial fastening applications requiring maximum reliability and durability.
