Value Collection 94003 Hex Lock Nut Nylon Insert 18-8 Ss 50 Pack

Product Description

The VALUE COLLECTION 94003 is a hex lock nut with a nylon insert locking style, manufactured from 18-8 stainless steel with an uncoated finish. The nylon insert grips the mating thread to resist loosening caused by vibration or dynamic loads, making it a reliable fastening solution in corrosion-prone or high-vibration environments. At 3/16 inches tall with a 3/8 inch width across flats, this nut fits standard UNC inch-series fasteners. It carries a right-hand thread direction. Plumbers, HVAC technicians, electricians, and general contractors reach for 18-8 stainless hardware when installations involve moisture, mild chemicals, or outdoor exposure.

This nylon insert lock nut is suited for residential and light commercial mechanical, plumbing, and electrical applications where vibration resistance and corrosion resistance are both required. Typical use cases include equipment mounting, pipe support systems, panel assemblies, and structural bracketing where a standard hex nut would back off over time. The UNC thread standard ensures broad compatibility with common inch-series bolts and threaded rod. Each package contains 50 nuts, making it practical for service stock or job-site quantities.

Compatibility

Designed for use with UNC inch-series bolts, screws, and threaded rod requiring a nylon insert hex lock nut with a 3/8 inch across-flats dimension.

Installation Notes

Install and remove with a standard open-end or box wrench sized for 3/8 inch across flats. Nylon insert lock nuts are intended for single-use applications — once the nylon insert has been run down a thread, its locking force is reduced and the nut should not be reused in critical joints. Power down or de-energize any equipment before accessing fastener assemblies in electrical or mechanical panels. Follow applicable mechanical and building codes for fastener specifications in structural or pressure-boundary applications.
