Value Collection MP34282 Hex Lock Nut 1/4-28 Nylon Insert

Product Description

The VALUE COLLECTION MP34282 is a 1/4-28 UNF hex lock nut with a nylon insert locking mechanism, manufactured from Grade 2 steel with a zinc finish. The nylon insert compresses against the mating thread when the nut is driven to position, creating resistance to loosening from vibration or torque. At 19/64 inches high with 7/16 inches across the flats, this nut fits standard 7/16-inch hex tooling. The zinc finish provides basic corrosion resistance for general-purpose indoor and light-duty applications. Installers in HVAC, plumbing, electrical, and general mechanical trades use this fastener wherever a reliable prevailing-torque lock nut is required.

This nut is suited for light-duty fastening applications in residential and commercial mechanical systems. Common uses include securing brackets, panels, fan assemblies, electrical enclosures, and plumbing fixture mounts where a standard 1/4-28 UNF thread pattern is specified. The right-hand thread direction matches the vast majority of UNF fastener assemblies. Its compact profile fits in confined spaces typical of equipment cabinets and control panels.

Compatibility

Designed for use with 1/4-28 UNF right-hand threaded fasteners and bolts in general mechanical, HVAC, electrical, and plumbing assembly applications.

Installation Notes

Installation requires a standard 7/16-inch wrench or socket. Power down equipment and relieve any system pressure before servicing fasteners on live mechanical assemblies. The nylon insert is a single-use locking feature — once fully driven and removed, the insert may not provide the same locking torque if reused. Follow applicable NEC, IPC, or IFGC guidelines when using fasteners in code-governed assemblies.
