Value Collection A996203 Hex Nut 3/4-18 Unf Brass 25pk

Product Description

The VALUE COLLECTION A996203 is a 3/4-18 UNF right-hand hex nut machined from brass. It is used to fasten threaded assemblies where a Unified National Fine thread pitch is required. The nut measures 1-7/64 inches across the flats and 41/64 inches in height, making it a standard hex profile suited for wrench-driven installation. Brass construction provides corrosion resistance and is well suited for applications where galling with steel fasteners is a concern. This package contains 25 nuts. Licensed plumbers, pipefitters, and maintenance technicians commonly use this nut in fluid system assemblies, instrumentation fittings, and general mechanical work.

This hex nut is appropriate for residential and commercial applications requiring a 3/4-18 UNF threaded connection. The fine thread pitch offers greater thread engagement per inch compared to coarse thread equivalents, which benefits applications where vibration resistance or precise torque control is needed. Typical installations include plumbing fixture connections, hydraulic and pneumatic fittings, and equipment maintenance tasks. The brass material is compatible with a range of media including water, air, and mild chemical environments.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified maintenance technicians. Ensure the mating threaded component is clean and free of burrs before engagement. Apply appropriate thread sealant if the connection is part of a fluid-carrying system. Hand-tighten first to confirm thread alignment before applying final torque with a standard hex wrench or socket.
