Professional Applications & Engineering Value

This 8-32 nylon insert lock nut delivers exceptional engineering value in applications where vibration-induced loosening poses significant reliability concerns. The cadmium yellow-chromate plated steel construction provides dual protection against corrosion and wear, while the nylon insert locking mechanism creates consistent friction that resists rotational movement under extreme conditions. Particularly valuable in aerospace assemblies and heavy machinery, this fastener maintains integrity where thermal cycling and dynamic stresses would compromise standard nuts. The Class 3B UNC thread fit ensures precise engagement with mating components, eliminating play and reducing the risk of thread damage during repeated maintenance cycles. Engineered to MS21044-N08 specifications, this lock nut provides a certified solution for permanent fastening requirements across industrial and transportation sectors.

Specification Summary & Compliance

This lock nut features 8-32 UNC coarse threads with Class 3B fit for precision thread engagement, manufactured to MS21044-N08 military specifications. The external hex drive measures 11/32" across flats with a total height of 9/32". The nylon insert provides reliable locking performance up to 250°F maximum temperature while maintaining vibration resistance. The cadmium yellow-chromate plating meets industry standards for corrosion protection, and the right-hand threading follows standardized installation conventions for consistent assembly operations.
