Value Collection R50000030 Hex Lock Nut 7/16-20

Product Description

The VALUE COLLECTION R50000030 is a 7/16-20 UNF hex lock nut with a nylon insert locking mechanism, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert deforms around the mating thread when the nut is driven down, creating prevailing torque that resists vibration-induced loosening without requiring secondary adhesives or locking washers. Standing 21/64 inches high with a 11/16-inch width across flats, this fastener is sized for standard open-end or box wrenches. Right-hand thread direction follows conventional UNF fastener practice. Trades working in HVAC equipment panels, plumbing fixture mounting, and electrical enclosure assembly commonly use this style of lock nut where re-torquing access is limited.

This nylon insert hex lock nut is suited for mechanical assemblies where vibration or thermal cycling could work a standard nut loose over time. Typical applications include blower housing fastening, equipment bracket mounting, control panel assembly, and pump or motor mounting hardware in both residential and light commercial installations. The zinc plating provides baseline corrosion resistance for indoor and protected outdoor environments. This nut is sold individually but requires a minimum order quantity of 100 units per order.

Compatibility

Designed as an OEM-style replacement or stock fastener for any assembly using a 7/16-20 UNF hex lock nut with nylon insert, including HVAC equipment, plumbing fixture hardware, and electrical enclosure mounting applications.

Installation Notes

Install using an appropriately sized open-end or box wrench; do not use an impact driver, as excessive torque can shear or displace the nylon insert. Nylon insert lock nuts are generally not recommended for reuse after removal, as the insert loses its locking effectiveness once fully compressed. Follow applicable equipment manufacturer torque specifications and relevant mechanical codes for the assembly being serviced. Ensure the mating bolt thread condition is clean and undamaged before installation.
