Blind Rivet Nut GESIPA Al M10×12×21 Countersunk Head for 4.0–6.5 mm, pack of 100

GESIPA blind rivet nut Al M10×12×21 with a countersunk head is an aluminium threaded insert designed to create robust internal threads in thin sheet materials where conventional tapping is not feasible. Supplied in a pack of 100, each rivet nut forms a load-bearing M10 thread in sheets with thicknesses from 4.0 to 6.5 mm. The countersunk head sits flush with the surface after installation, providing a neat finish for panels, enclosures and visible assemblies.

Advantages

These aluminium blind rivet nuts offer a combination of light weight and corrosion resistance appropriate for many metalworking and industrial applications. The countersunk head design ensures a flush fit, reducing snagging and improving the appearance of finished assemblies. Being blind fasteners, they can be installed from one side of the workpiece, which simplifies assembly in confined or inaccessible locations. Packaged as 100 pieces, they are convenient for production runs and maintenance stocks.

Suitable for

• Creating load-bearing internal M10 threads in thin metal sheets
• Fastening panels and covers in electrical enclosures and cabinets
• Automotive body repairs and component assembly
• Industrial machines and equipment where one-sided access is required
• Retrofit and maintenance tasks in sheet-metal constructions

Key specifications

• Material: aluminium
• Thread size: M10
• Shank dimensions: 12×21 mm (nominal length and diameter)
• Head type: countersunk
• Suitable sheet thickness: 4.0–6.5 mm
• Pack quantity: 100 pieces

How to use

Drill a correctly sized hole through the workpiece matching the rivet nut shank diameter. Insert the blind rivet nut into the hole so the countersunk head sits flush with the surface. Using a rivet nut installation tool or setting tool, pull the mandrel to deform the blind end and form a secure clinch against the backside of the sheet until the rivet nut is fully compressed and the M10 thread is formed. Remove the tool and fit the mating screw or bolt into the created internal thread. Verify a tight, perpendicular fit and that the head is flush with the material surface.

Usage recommendations

Use drill and installation equipment sized for M10 rivet nuts and follow the tool manufacturer's torque and setting parameters. For applications exposed to corrosive environments or higher mechanical loads, consider additional surface treatment or alternative materials. Inspect hole preparation and rivet nut seating before final assembly to ensure reliable threaded joints.
