Value Collection 34275 Hex Lock Nut 7/16-14 Nylon Insert

Product Description

The VALUE COLLECTION 34275 is a 7/16-14 UNC hex lock nut with a nylon insert locking mechanism, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert compresses against the mating thread to resist loosening under vibration and torque without damaging the fastener. Standing 15/32 inches high with a width across flats of 11/16 inches and a right-hand thread direction, this nut is sized for standard 7/16-14 UNC threaded rod, bolts, and stud applications. It is installed by licensed tradespeople and experienced technicians working in mechanical, HVAC, plumbing, and general assembly environments.

This hex lock nut is suited for residential and commercial applications where vibration resistance is required. Common install scenarios include equipment mounting, structural bracketing, duct system fastening, and mechanical panel assembly. The zinc-plated finish provides moderate corrosion resistance for indoor and protected outdoor use. The UNC thread standard makes it compatible with the widest range of American fastener stock.

Key Features

• Nylon insert locking style resists loosening from vibration without damaging threads
• Grade 2 steel construction for general-purpose mechanical strength
• Zinc-plated finish for corrosion resistance in typical service environments
• 7/16-14 UNC right-hand thread for broad fastener compatibility
• Standard hex profile accepts common wrenches and sockets

Compatibility

Designed for use with 7/16-14 UNC threaded bolts, rods, and studs in standard inch-measurement fastener applications.

Installation Notes

Install with a standard open-end or box wrench sized to 11/16 inches across flats. Power down or de-energize any equipment before performing fastener service on live mechanical or electrical assemblies. The nylon insert is single-use by design — once fully engaged and removed, the locking torque is reduced and the nut should be replaced. Follow applicable mechanical codes and equipment manufacturer torque guidance for the specific assembly.
