Value Collection 34288 Hex Lock Nut 3/4-16 Unf Grade B

Product Description

The VALUE COLLECTION 34288 is a 3/4-16 UNF Grade B hex lock nut with a nylon insert, designed for threaded fastening applications where vibration resistance is required. The nylon insert creates a prevailing-torque locking action that resists loosening under dynamic loads without requiring a secondary locking device. Constructed from steel with a zinc-plated finish for basic corrosion resistance, this nut measures 1-1/16 inches across the flats and 7/8 inches in height. It is a standard hardware component suited for mechanical assembly, maintenance, and repair tasks across plumbing, HVAC, and general trade work.

This hex lock nut is appropriate for use in residential and light commercial mechanical assemblies where a 3/4-16 UNF thread pattern is specified. Typical applications include equipment mounting, pipe support brackets, pump and motor assemblies, and other fastening points subject to vibration or cyclic loading. The zinc-plated finish offers a degree of protection in moderately dry indoor environments. Trade professionals and maintenance technicians working on mechanical systems will find this a straightforward drop-in fastener for standard UNF threaded connections.

Compatibility

Designed as a standard replacement or stock hex lock nut for any assembly requiring a 3/4-16 UNF Grade B prevailing-torque nut with nylon insert.

Installation Notes

Installation is performed with a standard 1-1/16 inch hex wrench or socket. Ensure the mating threaded fastener is clean and free of debris before assembly. Do not reuse nylon insert lock nuts after full removal, as the nylon locking element loses effectiveness after a single use cycle. No special certifications or licensed trade are required for standard fastener installation, though fastener selection should comply with applicable mechanical codes for the system being serviced.
