Value Collection N2H100CYPKGPR Hex Nut 1-8 Unc

Product Description

The VALUE COLLECTION N2H100CYPKGPR is a heavy hex nut threaded to 1-8 UNC (Unified National Coarse) specification, manufactured from A194 Grade 2H alloy steel and finished with a zinc yellow dichromate coating. This nut is designed for high-strength bolting applications where corrosion resistance and load-bearing capacity are critical. The 1-8 thread size indicates a 1-inch nominal diameter with 8 threads per inch. A194 Grade 2H is a recognized specification for heavy hex nuts used in pressure-containing and structural assemblies. Licensed plumbers, pipefitters, structural ironworkers, and industrial maintenance technicians regularly use this fastener in demanding mechanical and process-piping environments.

This hex nut is suited for use in flanged pipe connections, pressure vessel assemblies, structural steel bolting, and heavy industrial equipment installations. The zinc yellow dichromate finish provides a base level of corrosion resistance appropriate for indoor mechanical rooms, equipment skids, and covered structural applications. Right-hand thread direction follows standard UNC convention, making this nut compatible with standard 1-8 threaded rod, anchor bolts, and hex cap screws used across mechanical and process trades.

Key Features

• A194 Grade 2H alloy steel construction for high-strength, high-pressure bolting service
• 1-8 UNC right-hand thread for compatibility with standard 1-inch threaded fastener systems
• Zinc yellow dichromate finish provides corrosion resistance and surface identification
• 1.625 inches across flats for use with standard 1-5/8-inch wrench or socket
• 63/64-inch height (approximately 0.984 inches) — heavy hex profile for increased bearing surface
• Does not meet military specification requirements — intended for commercial and industrial use

Compatibility

Designed for use with standard 1-8 UNC threaded fasteners including threaded rod, hex bolts, and anchor bolts. Suitable for flanged pipe bolting, structural connections, and pressure vessel assemblies where A194 Grade 2H nuts are specified.

Installation Notes

Installation should be performed by qualified pipefitters, ironworkers, or mechanical tradespeople in accordance with applicable codes such as ASME B31.3 for process piping or AISC standards for structural steel. Ensure all mating threads are clean and free of debris before assembly. Lubricate threads as required by the joint specification — do not assume dry installation unless the design document specifies it. Always verify that the nut grade matches the bolt or stud specification required by the engineering drawing or code of record.
