Marson M39356 Insert Tool Mandrel 10-24

Product Description

The MARSON M39356 is a 10-24 threaded insert tool mandrel designed for use with the MARSON 39300 rivet nut and threaded insert tool. The mandrel threads directly into the tool nose and interfaces with the insert during the setting process, allowing technicians to install threaded inserts into thin-walled or hollow base materials. It is a consumable-style accessory that sees regular wear and is commonly replaced as part of routine tool maintenance. Technicians working with sheet metal, automotive panels, enclosures, or structural assemblies rely on correctly sized mandrels to ensure consistent, properly set inserts.

This mandrel is sized for 10-24 UNC threaded inserts, one of the most common thread sizes encountered in light-duty metal fabrication, HVAC equipment assembly, electrical enclosures, and general industrial applications. It is sold individually and is intended for professional tradespeople who require a direct replacement or spare mandrel for the 39300 insert tool.

Installation Notes

Installation of threaded inserts is typically performed by sheet metal workers, HVAC technicians, electricians, or general maintenance trades. Before changing or installing the mandrel, ensure the tool is fully depressurized or disconnected from any power source if applicable. Thread the mandrel securely into the tool nose by hand before applying any torque, and inspect the mandrel threads for wear before each use session to avoid cross-threading or failed insert sets.
