Threaded mandrel M12 for GESIPA FireFox blind rivet nut tool — for M6 rivet nuts

Threaded mandrel M12 designed for use with the GESIPA FireFox blind rivet nut tool, compatible with M6 blind rivet nuts. This replacement mandrel provides the correct M12-to-M6 thread interface required to install M6 rivet nuts with the FireFox system. It is intended as a service and spare part to restore tool functionality and ensure consistent installation quality of blind rivet nuts in metal and thin-sheet applications.

Advantages

The mandrel is manufactured to fit the FireFox tool's threaded spindle, delivering accurate alignment and repeatable engagement with M6 rivet nuts. It simplifies maintenance by allowing quick replacement of a worn or damaged mandrel without modifying the tool. The part supports reliable setting force transmission and helps maintain proper thread engagement during installation, contributing to consistent blind rivet nut seating and reduced rework.

Suitable for

• Replacement or maintenance of GESIPA FireFox blind rivet nut tools
• Installation of M6 blind rivet nuts in sheet metal and thin-walled components
• Light to medium production environments where blind rivet nuts are applied repeatedly
• Repair and service operations requiring original-fit tool components

Key specifications

• Thread connection: M12 mating thread for FireFox threaded spindle
• Compatible rivet nut size: M6 blind rivet nuts

How to use

Ensure the FireFox blind rivet nut tool is de-energised and free of load before changing components. Unscrew the existing mandrel from the tool spindle, inspect the spindle and surrounding parts for wear, then screw the M12 threaded mandrel into the spindle until fully seated and hand-tight. Verify correct thread engagement and perform a setting test with an M6 blind rivet nut on scrap material to confirm proper function before resuming normal work.

Recommendations

Regularly inspect mandrels for thread wear, deformation, or corrosion; replace when wear affects thread engagement or rivet nut setting quality. Use the mandrel with correctly specified M6 blind rivet nuts and follow the FireFox tool manufacturer's maintenance guidance to ensure consistent installation results.
