Professional Applications & Engineering Value

This 3/4"-10 UNC nylon insert locknut delivers critical vibration resistance where conventional fasteners fail. The 18-8 stainless steel construction provides inherent corrosion resistance, eliminating maintenance concerns in marine, chemical processing, and outdoor applications. The extra-wide thin profile offers maximum bearing surface while maintaining low profile dimensions, ideal for space-constrained assemblies in machinery, transportation equipment, and structural frameworks. The nylon insert locking mechanism creates consistent friction against mating threads, preventing loosening from vibration or thermal cycling while allowing for multiple reuses. With Class 3B precision threads ensuring perfect engagement with mating components, this locknut solves critical fastening challenges in heavy machinery, automotive systems, and industrial equipment where reliability is paramount.

Specification Summary & Compliance

This locknut features 3/4"-10 UNC coarse threads with Class 3B thread fit for precision engagement, right-hand thread direction, and external hex drive style. Dimensions include 1-1/4" width and 45/64" height in extra-wide thin profile configuration. The nylon insert maintains performance up to 250°F maximum temperature. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring regulatory compliance for industrial applications worldwide.
