Value Collection M47171 Steel Rivet Nut 5/16-18 Pack of 25

Product Description

The VALUE COLLECTION M47171 is a flat head steel rivet nut designed to create strong, threaded fastening points in thin sheet materials where access is limited to one side only. With a 5/16-18 UNC thread size and a grip range of 0.03 to 0.115 inches, this standard rivet nut installs quickly using a rivet nut tool, expanding on the blind side to lock in place. It is sold in a pack of 25 and is used across HVAC, electrical enclosure, automotive, and general sheet metal fabrication work. The flat head profile sits flush against the workpiece surface after installation.

This rivet nut is suited for light to medium sheet metal assemblies where a permanent threaded insert is needed without welding or access to the back side of the panel. Common applications include sheet metal ductwork brackets, electrical panel fabrication, equipment enclosures, and structural attachments in commercial and residential mechanical installations. Tradespeople in HVAC, electrical, and light manufacturing regularly use rivet nuts of this type when anchoring components to thin-gauge steel panels. The 27/64-inch drill size should be used to prepare the host material before installation.

Installation Notes

Installation is performed using a rivet nut setting tool matched to the 5/16-18 thread size. Drill the host material to 27/64 inch before inserting the rivet nut. Ensure the panel or substrate is properly supported and free of burrs at the drill hole before setting. Follow applicable fabrication standards and torque the mating fastener to the assembly design specification after the insert is fully set.
