Value Collection NLI20370NE-10LBBX Hex Lock Nut 3/8-16

Product Description

The VALUE COLLECTION NLI20370NE-10LBBX is a 3/8-16 hex lock nut featuring a nylon insert locking mechanism. Manufactured from Grade 2 steel with a zinc finish, this UNC-threaded fastener is designed to resist loosening under vibration and torque. The nylon insert creates interference with the mating thread, maintaining clamp load without the need for thread-locking compounds. At 15/32 inches in height and 9/16 inches across the flats, it fits standard hex tooling. Electricians, plumbers, HVAC technicians, and general trade contractors use this type of fastener in panel assemblies, equipment mounting, and mechanical connections where joint integrity is critical.

This hex lock nut is suited for general industrial and trade applications requiring a reliable, reusable locking fastener on 3/8-16 UNC threaded rod, bolts, or studs. Right-hand thread direction follows standard convention, making it compatible with typical fastener assemblies found in HVAC equipment mounting, electrical enclosures, plumbing supports, and structural connections. The zinc finish provides basic corrosion resistance appropriate for indoor and sheltered outdoor installations.

Compatibility

Designed as a standard replacement or general-use hex lock nut for any assembly using 3/8-16 UNC threaded fasteners.

Installation Notes

Installation requires a standard 9/16-inch hex wrench or socket. Ensure the mating bolt or stud is free of debris and damage before threading the nut by hand. Tighten to the torque specification required by the assembly or governing standard for the application. The nylon insert is designed for single-use locking performance — inspect the insert for deformation if reuse is being considered.
