Value Collection MP93631 Hex Lock Nut 7/16-20 Ss Pack 10

Product Description

The VALUE COLLECTION MP93631 is a 7/16-20 UNF hex lock nut with a nylon insert locking mechanism, manufactured from 18-8 stainless steel with a bright, uncoated finish. The nylon insert creates prevailing torque by deforming slightly around mating threads, resisting vibration loosening without damaging fastener threads. At 29/64 inches in height with a 5/8-inch width across flats, this nut fits standard hex tooling. The 18-8 stainless steel construction provides corrosion resistance suitable for wet, outdoor, or chemically exposed environments. Packaged in quantities of 10, this fastener is used by HVAC technicians, plumbers, electricians, and general trade professionals on assemblies requiring reliable thread retention.

This hex lock nut is suited for residential and light commercial mechanical assemblies where vibration resistance and corrosion resistance are required. Typical applications include equipment mounting, ductwork bracket fastening, piping support hardware, electrical enclosure assembly, and structural connections using 7/16-20 UNF threaded rod or bolt stock. The right-hand thread direction is standard for most North American mechanical assemblies. This part is sold in packs of 10, making it practical for service vans and job-site use where small fastener quantities are needed.

Installation Notes

Installation requires a standard hex socket or open-end wrench sized for a 5/8-inch width across flats. Nylon insert lock nuts are single-use by design and should not be reused after removal, as the locking torque is reduced once the nylon has been deformed. Always ensure mating threads are clean and free of debris before installation. Follow applicable mechanical codes and equipment manufacturer torque guidelines when assembling structural or pressure-bearing connections.
