Value Collection 34350 Hex Flange Lock Nut 5/16-18 Nylon Insert

Product Description

The VALUE COLLECTION 34350 is a hex flange lock nut with a nylon insert, designed to maintain thread engagement under vibration and dynamic loads. Built from Grade 2 steel with a zinc finish for basic corrosion resistance, this nut uses a nylon insert locking mechanism that grips the mating thread without requiring secondary hardware. The 5/16-18 UNC thread size is one of the most common inch-series fastener dimensions in light mechanical assemblies, HVAC equipment, electrical enclosures, and plumbing fixture mounting. Installation requires standard hand tools and is suited for any trade that works with threaded fasteners in mild-environment applications.

This lock nut is used in residential and light commercial applications where a reliable, reusable thread lock is needed without adhesive. Typical install scenarios include panel mounting, bracket fastening, equipment framing, and general mechanical assembly. The flanged base distributes clamping load over a wider bearing surface, reducing the chance of surface damage on softer substrates. It is sold individually with a minimum order quantity of 50 units per order.

Key Features

• Nylon insert locking style prevents loosening under vibration without thread-locking compound
• Hex flange design distributes clamping load and eliminates the need for a separate washer
• Grade 2 steel construction suitable for general-purpose, non-structural fastening
• Zinc finish provides basic corrosion resistance for indoor and mild-environment use
• Right-hand UNC thread conforms to standard inch-series fastener practice
• Width across flats of 0.5 inches fits standard 1/2-inch wrenches and sockets

Compatibility

Designed as a standard UNC inch-series hex flange lock nut compatible with 5/16-18 threaded bolts, studs, and screws in general mechanical assembly applications.

Installation Notes

Install and remove with a standard 1/2-inch wrench or socket. Power down or de-energize any equipment before accessing fastener locations in live electrical or HVAC panels. Nylon insert lock nuts are reusable but locking effectiveness decreases with repeated removal and reinstallation. Do not exceed the material and finish ratings in high-temperature, high-moisture, or chemically aggressive environments.
