Value Collection MP34284 Hex Lock Nut 3/8-24 Nylon Insert

Product Description

The VALUE COLLECTION MP34284 is a nylon insert hex lock nut designed to resist loosening caused by vibration and torque in threaded fastener assemblies. Built to a 3/8-24 UNF thread specification with a right-hand thread direction, this Grade 2 steel nut features a zinc finish for corrosion resistance in light-duty service conditions. The nylon insert creates interference with the mating bolt thread, providing a reliable prevailing-torque locking action without the need for adhesives or additional locking hardware. Plumbers, HVAC technicians, electricians, and general mechanical tradespeople use this style of fastener in panel assemblies, equipment mounting, and piping support structures.

This hex lock nut is suited for inch-measurement fastener applications requiring UNF threading. It is appropriate for use in residential and light commercial mechanical and electrical installations where a standard nylon insert prevailing-torque lock nut is specified. The zinc finish provides a baseline level of corrosion protection for indoor and sheltered outdoor environments. Minimum order quantity is 50 pieces, sold as individual units per package.

Key Features

• Nylon insert locking style provides vibration-resistant prevailing torque without adhesives
• 3/8-24 UNF right-hand thread for compatibility with standard inch-series fastener systems
• Grade 2 steel construction suitable for light to medium-duty mechanical assemblies
• Zinc finish coating offers baseline corrosion resistance for indoor and sheltered applications
• 15/32 inch height and 9/16 inch width across flats for standard hex tooling

Compatibility

Designed as a standard nylon insert hex lock nut for use with 3/8-24 UNF-threaded bolts and studs in inch-measurement fastener assemblies.

Installation Notes

Install using a standard open-end or box wrench sized for 9/16 inch across flats. Power down or de-energize any equipment before accessing fastener locations in electrical or mechanical panels. Do not reuse nylon insert lock nuts after removal, as the locking insert loses effectiveness once the prevailing torque is overcome. Follow applicable mechanical codes and equipment manufacturer torque guidelines when specified.
