Value Collection 34273 Hex Lock Nut 5/16-18 Zinc-plated

Product Description

The VALUE COLLECTION 34273 is a 5/16-18 UNC hex lock nut featuring a nylon insert locking style. The nylon insert compresses against the bolt thread to resist loosening from vibration and torque without damaging the fastener. Manufactured from Grade 2 steel with a zinc-plated finish, this nut is suited for general-purpose mechanical and structural assemblies where corrosion resistance and reliable thread locking are required. The right-hand thread conforms to standard UNC inch-series fastener specifications. Electricians, HVAC technicians, plumbers, and general tradespeople will find this nut appropriate for panel mounting, equipment fastening, and utility hardware applications.

This hex lock nut is used in residential and light commercial mechanical assemblies, equipment mounting, and general fastening applications where a 5/16-18 UNC thread pattern is specified. The zinc plating provides a base level of corrosion protection suitable for dry to mildly exposed indoor environments. It is sold individually per package, with a minimum order quantity of 100 pieces, making it appropriate for stocking in trade shops, service vehicles, or facilities maintenance operations.

Key Features

• Nylon insert locking style resists loosening under vibration without thread damage

Compatibility

Designed as a standard UNC inch-series hex lock nut for use with 5/16-18 threaded bolts, studs, and rods in general mechanical and trade fastening applications.

Installation Notes

Install using a standard 1/2-inch wrench or socket driver. Ensure the mating bolt or stud is clean and free of damage before threading on the nut. Nylon insert lock nuts are generally intended for single-use applications, as repeated removal can degrade the insert locking force. Power down or de-energize any equipment before servicing fasteners in electrical or HVAC panel assemblies.
