Value Collection A996418 Square Nuts 5/16-18 Zinc Plated 100pk

Product Description

The VALUE COLLECTION A996418 is a zinc-plated steel square nut sized for 5/16-18 unified coarse thread fastener applications. Each nut measures 9/16 inches across the square and 17/64 inches in height, providing a broad bearing surface that resists pull-through in wood, structural framing, and light fabrication assemblies. The zinc plating delivers baseline corrosion resistance suitable for indoor and sheltered outdoor installations. This pack contains 100 nuts, making it a practical bulk option for contractors and maintenance technicians who need reliable threaded hardware on hand.

Square nuts are commonly used in construction, HVAC equipment mounting, electrical panel framing, plumbing support structures, and general mechanical assemblies where a wrench-free or embedded-nut application is required. The flat sides allow the nut to seat flush against channel iron, unistrut, timber, and similar substrates without spinning. These are installed by licensed tradespeople across multiple disciplines wherever a 5/16-18 threaded connection needs a larger bearing footprint than a standard hex nut provides.

Key Features

• 5/16-18 unified coarse thread for broad fastener compatibility
• 9/16 inch square width provides increased bearing surface versus standard hex nuts
• 17/64 inch overall height for a low-profile seating profile
• Zinc-plated steel construction for corrosion resistance in sheltered environments
• Pack of 100 units supports bulk installation and inventory stocking

Compatibility

Designed as a standard square nut for use with 5/16-18 threaded bolts, screws, and all-thread rod in residential and light commercial fastener applications.

Installation Notes

Square nuts are installed by hand or with standard open-end, box-end, or socket wrenches sized to fit a 9/16 inch drive. Always de-energize any electrical or mechanical system before working in proximity to live components. Ensure mating thread pitch and diameter match before installation to avoid cross-threading or joint failure. Torque to the fastener manufacturer's specification for the bolt grade and application.
