Professional Applications & Engineering Value

This 3/4"-10 nylon insert locknut delivers exceptional engineering value in demanding industrial environments where vibration-induced loosening compromises safety and operational integrity. The 18-8 stainless steel construction provides superior corrosion resistance for applications exposed to moisture, chemicals, or outdoor elements, while the extra wide hex profile enables higher torque application without damaging the fastener. The nylon insert locking mechanism creates consistent friction against mating threads, effectively dampening vibrations in machinery, conveyor systems, and structural assemblies. With UNC coarse threading and right-hand thread direction, this locknut offers quick installation and removal while maintaining reliable locking performance through multiple use cycles, making it ideal for maintenance-heavy applications requiring frequent disassembly.

Specification Summary & Compliance

This locknut features 3/4"-10 UNC coarse threading with Class 2B thread fit for precise dimensional accuracy and reliable engagement. The external hex drive style accommodates standard wrenching tools, while the 1-1/4" width and 1" height provide substantial bearing surface. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards are met for industrial applications.
