Professional Applications & Engineering Value

This 316 stainless steel locknut with distorted thread technology provides critical vibration resistance in demanding industrial environments where constant motion and stress would compromise standard fasteners. The center lock design creates consistent friction along the thread engagement, preventing loosening without damaging mating components. The UNC coarse thread pattern offers faster installation in heavy machinery, construction equipment, and transportation applications where maintenance time is critical. With 316 stainless steel material, this locknut maintains integrity in corrosive environments including chemical processing, marine applications, and outdoor infrastructure. The external hex drive and standard hex profile ensure compatibility with existing tooling while providing sufficient torque capability for high-load applications.

Specification Summary & Compliance

This heavy-duty locknut features 3/4"-10 UNC coarse threading with Class 2B thread fit for precise dimensional accuracy and reliable performance. The distorted thread locking mechanism provides permanent vibration resistance without requiring additional locking elements. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. Physical dimensions include 1 1/8" width across flats and 41/64" height for standard tool compatibility and sufficient thread engagement depth.
