Value Collection R52001587 Hex Lock Nut 1/4-20

Product Description

The VALUE COLLECTION R52001587 is a 1/4-20 hex lock nut with a nylon insert locking style, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert creates interference against the mating thread, resisting loosening from vibration and torque without damaging the fastener. At 19/64 inches high and 7/16 inches across the flats, this nut follows standard UNC thread specifications with a right-hand thread direction. It is a general-purpose fastener suited for mechanical assemblies, light structural connections, and equipment fabrication where a reliable, reusable locking nut is required.

This hex lock nut is used in a wide range of residential and light commercial applications including HVAC equipment assembly, electrical enclosure hardware, plumbing fixture mounting, and general sheet metal or frame work. The zinc-plated finish provides basic corrosion resistance in dry to mildly humid environments. Installers working with standard 1/4-20 threaded rod, bolts, or machine screws will find this nut compatible with common UNC fastener stock. Minimum order quantity is 50 pieces per order.

Installation Notes

Install using a standard 7/16-inch open-end or combination wrench. De-energize and isolate any equipment before performing fastener work on live assemblies. The nylon insert is rated for single or limited reuse — inspect the insert for wear if the nut has been removed and reinstalled multiple times. Do not exceed the torque rating appropriate for Grade 2 hardware as referenced in standard fastener torque tables.
