The MARSON m47940 is an aluminum nut insert designed for creating strong, reusable threaded connections in thin-sheet base materials. Commonly called a rivet nut or thread insert, this fastener is installed with a setting tool to provide a load-bearing internal thread where conventional tapping is not practical. The 10-24 thread size suits a wide range of light-duty mechanical assembly applications. Each package contains 100 inserts. Aluminum construction keeps weight low and offers adequate corrosion resistance for indoor and sheltered environments.
This nut insert is used in sheet metal fabrication, HVAC panel assembly, electrical enclosures, and similar trade applications where access to only one side of the workpiece is available. It is suited for residential and light commercial projects where a secure threaded anchor is needed in aluminum, steel, or composite panels. Installers in HVAC, electrical, and general mechanical trades commonly use this fastener when assembling equipment panels, brackets, and housings.
Designed as an OEM-style rivet nut insert for use in thin-sheet materials requiring a 10-24 threaded anchor point.
Installation is performed using a rivet nut setting tool sized for 10-24 inserts; confirm mandrel compatibility before use. Ensure the base material hole diameter matches the manufacturer specification for the insert body before setting. Deburr holes prior to insertion to prevent damage to the insert flange. Power down any panel or enclosure fully before installing inserts in energized equipment.
