Value Collection R50000351 Hex Lock Nut 3/8-16

Product Description

The VALUE COLLECTION R50000351 is a distorted-thread hex lock nut designed to resist loosening under vibration and dynamic loads. Sized at 3/8-16 UNC, it is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance for general-purpose applications. The nut measures 21/64 inches in height with a 9/16-inch width across flats, making it a standard fit for common hex tooling. The distorted-thread locking mechanism creates interference with the mating bolt thread, eliminating the need for a secondary locking device. This fastener is installed by maintenance technicians, electricians, plumbers, and general contractors across a wide range of assemblies.

This hex lock nut is suited for residential, commercial, and light industrial fastening applications where a reliable thread lock is required without adhesives or split washers. It is commonly used in equipment mounting, panel assemblies, pipe support bracketing, and structural connections where standard 3/8-16 UNC threaded fasteners are specified. The right-hand thread direction is consistent with the vast majority of standard threaded hardware applications.

Key Features

• Distorted-thread locking style resists loosening from vibration without additional locking hardware
• 3/8-16 UNC thread size for compatibility with standard inch-series fasteners
• Grade 2 steel construction suitable for general-purpose mechanical applications
• Zinc-plated finish provides basic corrosion protection in dry to mildly humid environments
• Right-hand thread direction matches standard threaded bolt and stud stock
• 9/16-inch width across flats fits standard hex wrenches and sockets

Compatibility

Designed as a standard replacement or new-installation hex lock nut for any assembly using 3/8-16 UNC threaded bolts or studs requiring a distorted-thread locking nut.

Installation Notes

Install with a standard 9/16-inch hex wrench or socket driver. Ensure the mating bolt or stud is clean and free of debris before threading the nut. Because the distorted-thread design creates intentional interference, slightly higher installation torque is normal compared to a standard hex nut. Do not reuse distorted-thread lock nuts after removal, as the locking effectiveness may be reduced.
