Gesipa Blind Rivet Nut Aluminium M4 x 12 mm Countersunk Head Grip 1.5-3.5 mm (500 Pack) 1455346

In sheet metal fabrication shops and automotive assembly lines, technicians often need to create strong, reusable threads in thin panels where access is limited to one side. The Gesipa blind rivet nut in aluminium with M4 internal thread and countersunk head delivers exactly that: a reliable, vibration-resistant fastening point in materials from 1.5 to 3.5 mm thick. Supplied in a bulk pack of 500 pieces, it keeps production running without constant restocking.

Why choose it

These rivet nuts install quickly from one side using standard blind rivet nut setting tools, eliminating the need for welding, tapping, or access to the rear of the workpiece. The aluminium body offers excellent corrosion resistance and is lightweight, while the countersunk head sits flush with the surface for a clean, professional finish. The wide grip range covers common sheet thicknesses, reducing the number of different fasteners you need to stock.

Ideal use cases

• Attaching brackets, panels, and components to thin-walled enclosures
• Creating load-bearing threads in aluminium profiles, sheet metal, and plastic assemblies
• Automotive bodywork, trailer construction, and HVAC ducting
• Repair and maintenance where original threads are stripped or inaccessible

Good to know

For optimal setting, use a rivet nut tool with the correct mandrel for M4 and ensure the hole diameter matches the recommended 6.1 mm. The 500-piece pack is ideal for high-volume production or workshop stock. These rivet nuts are permanent fasteners and should be selected based on the total material thickness within the specified grip range.
