Value Collection R50000032 Hex Lock Nut 9/16-18

Product Description

The VALUE COLLECTION R50000032 is a 9/16-18 UNF hex lock nut with a nylon insert locking style, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert compresses against mating threads to resist loosening caused by vibration and torque, making it suitable for demanding mechanical assemblies. It measures 23/64 inches in height with a 7/8-inch width across flats and weighs approximately 0.031 pounds. Right-hand thread direction conforms to standard UNF fastener practice. Plumbers, HVAC technicians, electricians, and general mechanical tradespeople use this type of nut across a wide range of equipment assembly and maintenance tasks.

This nylon insert lock nut is used in residential and light commercial mechanical applications where vibration resistance is required and a standard hex lock nut profile is appropriate. Common install scenarios include equipment mounting, bracket fastening, and general structural assembly where the fastener must retain its clamp load over time. The UNF thread standard makes it compatible with inch-system threaded assemblies across HVAC, plumbing, and electrical equipment installation.

Key Features

• Nylon insert locking style resists loosening from vibration without damaging mating threads
• 9/16-18 UNF right-hand thread for compatibility with standard inch-system fasteners
• Grade 2 steel construction provides adequate tensile strength for light to medium mechanical loads
• Zinc-plated finish offers basic corrosion resistance in typical indoor service environments
• 23/64 inch height and 7/8 inch width across flats fits standard hex tooling

Compatibility

Designed as a standard UNF nylon insert hex lock nut for use in any inch-system threaded assembly requiring a 9/16-18 fastener with vibration-resistant locking.

Installation Notes

Installation requires a standard 7/8-inch open-end or box wrench. Power down or de-energize any equipment before performing fastener work on mechanical assemblies. Do not reuse nylon insert lock nuts after removal, as the nylon locking element loses effectiveness once it has been torqued and removed. Follow applicable mechanical codes and equipment manufacturer guidelines for proper fastener torque procedures.
