Value Collection 101178 Hex Nut 7/8-9 316 Ss Unc

Product Description

The VALUE COLLECTION 101178 is a heavy-duty hex nut threaded to 7/8-9 UNC specifications and machined from Grade 316 stainless steel with a bright, uncoated finish. Grade 316 stainless provides superior corrosion resistance compared to 304-series alloys, making this nut well suited to harsh or wet environments. The right-hand thread conforms to Unified National Coarse (UNC) standards, ensuring compatibility with standard 7/8-9 fastener assemblies. Plumbers, pipefitters, HVAC technicians, and pool service professionals routinely spec 316 SS hardware where chlorides, moisture, or chemical exposure would degrade carbon steel or lower-grade stainless fasteners.

This hex nut is appropriate for use in plumbing system assemblies, pool and spa mechanical equipment, HVAC unit bases and structural frames, and general industrial or marine-adjacent applications where corrosion resistance is a priority. The 1-7/16 inch across-flats dimension accepts a standard 1-7/16 inch wrench or socket. The 55/64 inch height accommodates full thread engagement on properly sized bolts and threaded rod. Sold individually, it fits applications requiring single-piece replacements or custom assembly quantities.

Key Features

• Grade 316 stainless steel construction for strong resistance to chlorides and corrosive environments
• 7/8-9 UNC right-hand thread for compatibility with standard Unified National Coarse fastener assemblies
• Bright uncoated finish maintains dimensional accuracy and allows visual inspection of material
• 1-7/16 inch across-flats width fits standard SAE wrench and socket sizes
• 55/64 inch nut height provides full thread engagement depth

Compatibility

Designed for use in any 7/8-9 UNC threaded fastener assembly requiring Grade 316 stainless steel hardware, including plumbing, pool equipment, HVAC structural, and general industrial applications.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with fastener torque requirements for the specific assembly. Always de-energize, depressurize, or shut off the relevant system before servicing fasteners in mechanical assemblies. Use a calibrated torque wrench and consult the equipment manufacturer's fastener specifications for the appropriate torque value. Avoid mixing stainless steel fasteners with dissimilar metals in submerged or high-moisture applications to minimize galvanic corrosion risk.
