Value Collection R52001151 5/16-24 Un Steel Hex Nut

Product Description

The VALUE COLLECTION R52001151 is a 5/16-24 UN steel hex nut designed for use with machine screws and threaded fastener assemblies. It features a right-hand thread direction and a 2B class of fit, which is the standard internal thread tolerance class for general-purpose inch-series fasteners. The nut measures 9/16 inches across flats and 0.225 inches in height. A zinc-plated finish provides basic corrosion resistance for typical indoor and light-duty applications. This nut is sold individually but carries a minimum order quantity of 100 units, making it suited for contractors, MRO buyers, and shop stock replenishment.

This hex nut is appropriate for light to medium-duty threaded fastening applications across mechanical, structural, and general assembly work. It is commonly used in HVAC equipment assembly, electrical panel fabrication, plumbing fixture mounting, and general trade maintenance. The 5/16-24 UN fine thread pitch provides good thread engagement and resistance to loosening under vibration compared to coarse-thread equivalents, making it a practical choice in applications where vibration is a factor.

Key Features

• 5/16-24 UN fine thread for improved vibration resistance over coarse-thread alternatives
• 2B class of fit — standard general-purpose internal thread tolerance for reliable mating
• 9/16 inches across flats — compatible with standard hex wrenches and sockets
• Zinc-plated steel construction for basic corrosion protection
• Right-hand thread direction — standard installation orientation
• Sold per piece with a minimum order quantity of 100 units

Compatibility

Designed for use with 5/16-24 UN externally threaded fasteners including machine screws and bolts with a 2A external thread class of fit.

Installation Notes

Installation is performed by hand-threading the nut onto a compatible 5/16-24 UN machine screw or bolt, then tightening with a standard 9/16-inch hex wrench or socket. Always ensure the mating fastener thread class and pitch match before assembly to avoid cross-threading. Do not overtighten zinc-plated nuts in applications where the coating integrity must be maintained. Follow applicable mechanical and structural codes for the specific assembly being fastened.
