Value Collection 93857 Heavy Hex Nut 7/8-9 18-8 Stainless Steel

Product Description

The VALUE COLLECTION 93857 is a heavy hex nut threaded to 7/8-9 UNC specification in 18-8 stainless steel. Heavy hex nuts carry a wider and taller profile than standard hex nuts, distributing clamping load across a larger bearing surface. The 18-8 stainless steel alloy provides solid corrosion resistance, making this nut appropriate for wet, outdoor, and chemically active environments. The right-hand thread conforms to Unified National Coarse (UNC) standards. Width across flats measures 1-7/16 inches and height measures 55/64 inches. Plumbers, pipefitters, electricians, and general mechanical contractors reach for heavy hex nuts where vibration resistance and load distribution are priorities.

This nut is suited for structural bolting, pipe flange assemblies, equipment mounting, and mechanical connections where a coarse 7/8-9 thread is called out. The stainless steel construction holds up in humid mechanical rooms, rooftop equipment installations, pool equipment enclosures, and coastal environments. Sold in a package quantity of 10, with a minimum order quantity of 1 package.

Key Features

• Heavy hex profile for increased bearing surface and load distribution
• 18-8 stainless steel construction for corrosion resistance in wet and outdoor environments
• 7/8-9 UNC right-hand thread for compatibility with standard coarse-thread fastener systems
• Width across flats of 1-7/16 inches for use with standard heavy hex wrenches and sockets
• Height of 55/64 inches provides additional thread engagement depth versus standard hex nuts
• Packaged in quantities of 10 to support job-site and shop stocking needs

Compatibility

Designed as a standard UNC heavy hex nut for use with 7/8-9 threaded bolts, studs, and threaded rod in mechanical, plumbing, electrical, and structural applications.

Installation Notes

Installation is performed by mechanical, plumbing, or electrical tradespeople depending on the application. Always de-energize or depressurize the assembly before servicing fasteners in active systems. Use a properly sized 1-7/16-inch heavy hex socket or open-end wrench to avoid rounding the flats. Consult applicable codes such as ASME or AISC for torque and joint requirements specific to the assembly.
