Value Collection NLI20250NE-050B Hex Lock Nut 1/4-20 Steel

Product Description

The VALUE COLLECTION NLI20250NE-050B is a 1/4-20 UNC hex lock nut with a nylon insert locking style, manufactured from steel. The nylon insert creates friction against mating threads to resist loosening caused by vibration or torque, making it a reliable fastening solution for mechanical and structural assemblies. This nut measures 0.225 inches in height and 0.439 inches across flats, conforming to ASME B 18.16.6 standards. It is suited for electricians, HVAC technicians, plumbers, and general tradespeople who require a secure, reusable threaded fastener in light to medium-duty applications.

This hex lock nut is used in a wide range of trade and industrial applications where vibration resistance is required. Common install scenarios include securing panels, brackets, equipment mounts, and conduit supports. The 1/4-20 UNC thread is one of the most widely used inch-series thread standards, making this nut compatible with a broad range of bolts, screws, and threaded rod in residential and light commercial work. This listing covers a minimum order quantity of 50 pieces, supplied as a single package quantity.

Compatibility

Designed for use with any 1/4-20 UNC inch-series threaded fastener including bolts, cap screws, and threaded rod meeting standard UNC thread specifications.

Installation Notes

Install using an appropriately sized wrench or socket matching the 0.439-inch across-flats dimension. The nylon insert is designed for one primary use — repeated removal and reinstallation may reduce locking effectiveness over time. Ensure the mating bolt or screw is free of damage or debris before threading the nut on. Follow applicable mechanical and electrical codes, including NEC requirements where fasteners are used in electrical enclosures or equipment mounts.
