Value Collection CD557382 Hex Nut 1/2-13 Grade 2 Steel

Product Description

The VALUE COLLECTION CD557382 is a 1/2-13 hex nut manufactured from Grade 2 steel with a bright, uncoated finish. It features a right-hand UNC thread and is designed for standard bolted assembly applications across a wide range of mechanical, structural, and industrial installations. The nut measures 7/8 inches across the flats and 31/64 inches in height, conforming to ASME B1.1 and ASME B18.2.2 dimensional and tolerance standards. With a 2B thread fit class and a hardness range of 24 to 35 HRC, this fastener is suited for general-purpose use where a standard-duty, non-coated steel nut is appropriate.

This hex nut is used in general mechanical assembly, light structural connections, and equipment fabrication. It is commonly installed by maintenance technicians, pipefitters, electricians, HVAC installers, and general tradespeople wherever a 1/2-13 UNC threaded fastener connection is required. The uncoated bright finish makes it suitable for indoor or dry environments where corrosion resistance is not a primary requirement. It is ordered in multiples of 50 units per minimum order quantity.

Installation Notes

Install using a standard 7/8 inch open-end, box, or socket wrench. Power down or de-energize any connected equipment before performing fastener work in electrical or mechanical panels. Apply thread engagement consistent with ASME guidelines for the fastener grade and application load. Do not use in applications requiring corrosion resistance, military-specification compliance, or a higher material grade without substituting an appropriately rated fastener.
