Professional Applications & Engineering Value

This heavy-duty locknut addresses critical vibration-induced loosening challenges in industrial machinery, construction equipment, and transportation systems. The distorted thread technology creates controlled interference that maintains clamping force under extreme dynamic loads, eliminating the need for secondary locking devices. Manufactured from zinc-plated steel with ASTM Grade C certification, this UNC coarse thread locknut delivers reliable performance in corrosive environments while providing sufficient strength for structural applications. The external hex drive style and standard profile ensure compatibility with existing tooling, reducing installation time and maintenance costs across manufacturing facilities, assembly lines, and equipment maintenance operations.

Specification Summary & Compliance

This industrial locknut features precision Class 2B thread fit with 1 1/8"-7 UNC coarse thread specification and right-hand thread direction. The top lock distorted thread design ensures consistent locking performance while maintaining dimensional accuracy. Manufacturing compliance includes ASTM Grade C strength classification, REACH (EC 1907/2006) compliance for substance restrictions, and RoHS 3 (2015/863/EU) environmental standards. Physical dimensions include 1 11/16" width and 1" height with standard hex nut profile for universal application compatibility.
