Value Collection 7-N-50C Hex Lock Nut 1/2-13 Unc Nylon Insert

Product Description

The VALUE COLLECTION 7-N-50C is a 1/2-13 UNC hex lock nut with a nylon insert, designed to resist vibration-induced loosening in threaded fastener assemblies. Constructed from brass, this nut measures 3/4 inches across the flats and stands 19/32 inches high. The nylon insert creates a friction lock against the bolt thread without damaging the mating fastener, making it well suited for mechanical, plumbing, and light structural applications where joint integrity under vibration is a priority. Electricians, plumbers, and general tradespeople regularly specify nylon insert lock nuts wherever standard hex nuts are insufficient for the service environment.

This lock nut is used in residential and light commercial applications where a reliable, reusable thread-locking solution is needed without adhesives or chemical compounds. Common scenarios include equipment mounting, pipe hanger hardware, electrical enclosure assembly, and HVAC component brackets. The brass construction offers natural corrosion resistance, making it appropriate for damp or mildly corrosive environments where steel fasteners would be a liability.

Key Features

• 1/2-13 UNC thread specification for compatibility with standard unified coarse thread fasteners
• Nylon insert locks against bolt threads to resist loosening from vibration without thread damage
• Brass construction provides corrosion resistance in damp or mildly corrosive service environments
• 3/4 inches across flats for use with standard 3/4 inch wrench or socket
• 19/32 inches height provides full nylon insert engagement along the thread length
• Uncoated finish — no plating to flake or degrade over time

Compatibility

Designed as an OEM-style replacement or general-use hex lock nut for any application requiring a 1/2-13 UNC nylon insert lock nut in brass.

Installation Notes

Installation requires a standard 3/4 inch open-end wrench or socket. Always ensure the mating bolt threads are clean and free of debris before driving the nut to seat the nylon insert properly. Nylon insert lock nuts are reusable but should be inspected after removal — replace the nut if the nylon insert shows deformation or loss of resistance. Follow applicable mechanical or electrical codes for fastener torque requirements based on joint load and material.
