Value Collection SQNI20310-100BX 5/16-18 Steel Square Nut

Product Description

The VALUE COLLECTION SQNI20310-100BX is a zinc-plated steel square nut sized for 5/16-18 UNC thread applications. Each nut measures 9/16 inches across the square width and 17/64 inches in overall height. The zinc plating provides basic corrosion resistance for indoor and light-duty outdoor installations. Right-hand thread direction follows standard fastener convention. This box contains 100 nuts, making it suited for production work, maintenance stockrooms, or any application where consistent fastener supply is needed. Electricians, plumbers, HVAC techs, and general tradespeople reach for square nuts when working with channel framing, strut systems, or structural steel where a larger bearing surface is required.

Square nuts in 5/16-18 are commonly used with unistrut and similar channel-type mounting systems, junction box brackets, equipment supports, and light structural assemblies. They seat flush against channel slots and resist spinning during tightening, which speeds installation in tight or hard-to-reach locations. This size is a standard fit for trade rough-in work and equipment mounting across residential and light commercial projects.

Key Features

• 5/16-18 UNC right-hand thread for compatibility with standard inch-series hardware
• 9/16 inch square width provides increased bearing surface compared to hex nuts
• Zinc plating for basic corrosion resistance
• Steel construction for reliable tensile strength in structural and mechanical applications
• Box quantity of 100 supports production and maintenance inventory needs

Compatibility

Designed for use with 5/16-18 UNC threaded fasteners in standard inch-measurement applications, including channel strut systems, structural brackets, and general mechanical assemblies.

Installation Notes

Installation requires a standard 9/16 inch wrench or socket. Power down or de-energize any equipment before securing hardware near electrical components. Follow applicable mechanical and structural codes for torque and fastener spacing requirements on structural assemblies. Do not use damaged or cross-threaded nuts, as compromised threads reduce clamp load and can cause joint failure.
