Value Collection MSC-72047632 Hex Nut 1/2-13 Galvanized

Product Description

The VALUE COLLECTION MSC-72047632 is a 1/2-13 UNC hex nut manufactured from A563 Grade DH steel with a hot-dipped galvanized finish. Grade DH designates a heavy hex nut meeting ASTM A563 mechanical requirements for proof load and hardness, making it suitable for structural and high-strength bolted connections. The hot-dipped galvanized coating provides corrosion resistance in outdoor, wet, or chemically active environments. The nut features right-hand threading and measures 7/8 inch across the flats with a height of 31/64 inch. Plumbers, electricians, HVAC technicians, and general contractors use this fastener when assembling structural connections that require a corrosion-resistant, high-strength nut conforming to ASTM standards.

This hex nut is suited for residential and commercial applications where bolted connections are exposed to moisture or corrosive conditions, including mechanical equipment mounting, pipe support systems, structural steel framing, and outdoor electrical enclosure assembly. The 1/2-13 UNC thread size is one of the most common thread forms in North American trade work, compatible with standard 1/2-inch threaded rod, bolts, and hardware widely used across HVAC, plumbing, and electrical installations. Sold individually with a minimum order quantity of 50 pieces.

Key Features

• A563 Grade DH steel construction meets ASTM proof load and hardness requirements for structural bolted connections
• Hot-dipped galvanized finish delivers corrosion resistance in outdoor and wet service environments
• 1/2-13 UNC right-hand thread is a standard North American thread form for broad hardware compatibility
• 7/8 inch across flats fits standard 7/8-inch wrenches and sockets
• 31/64 inch height suits typical structural and mechanical fastening applications

Compatibility

Designed for use with 1/2-13 UNC threaded bolts, threaded rod, and studs in standard North American fastener assemblies requiring an A563 Grade DH heavy-duty hex nut.

Installation Notes

Installation is performed by hand-tightening onto a compatible 1/2-13 UNC threaded fastener, then torquing with a standard 7/8-inch open-end, box-end, or socket wrench. Follow applicable project specifications or code requirements such as AISC or RCSC guidelines for structural bolted connections when torque values are required. Inspect threads for damage or contamination before assembly. Do not use impact tools at excessive speed, as this can strip the galvanized coating or damage the thread form.
