Value Collection 317075PR Hex Nut 5/16-18 Grade 2 Steel

Product Description

The VALUE COLLECTION 317075PR is a 5/16-18 UNC hex nut manufactured from Grade 2 steel with a bright, uncoated finish. This standard hex nut provides a reliable threaded fastening point for bolts, threaded rod, and machine screws in general-purpose assemblies. It measures 1/2 inch across the flats and 0.2656 inches in height, making it a direct fit for common 5/16-inch fastener applications. Right-hand thread direction follows standard UNC convention. Electricians, plumbers, HVAC techs, and general contractors use this nut in panel mounting, equipment anchoring, strut channel assembly, and structural attachment tasks where a Grade 2 steel fastener meets load requirements.

This hex nut is suited for light- to medium-duty applications in residential and commercial construction, mechanical rooms, and equipment installations. It is commonly used with 5/16-18 bolts and threaded rod in strut and unistrut assemblies, equipment bases, junction box mounting, and general hardware applications where corrosion resistance is not a primary concern. The uncoated finish is appropriate for indoor or protected environments. This SKU is sold as a single nut with a minimum order quantity of 100 pieces.

Installation Notes

Install using a 1/2-inch open-end, box, or socket wrench. Ensure mating bolt or threaded rod is also 5/16-18 UNC to prevent cross-threading. Power down or de-energize any equipment before fastening hardware in electrical or mechanical enclosures. Do not exceed the load rating appropriate for Grade 2 steel fasteners in structural or high-vibration applications where a higher material grade may be required.
