Blind rivet nut GESIPA M5 7×13.5 mm for 1.5–4 mm sheets, 90° countersunk head

GESIPA blind rivet nut M5 with a body size of 7×13.5 mm and a 90° countersunk head creates a permanent internal thread from one side of the workpiece. Designed for sheet thicknesses between 1.5 and 4 mm, this blind rivet nut installs into panels where rear-side access is limited. The 90° countersunk head provides flush seating in countersunk holes and distributes load across the surface for secure fastening in metal and thin-sheet applications.

Advantages

This blind rivet nut offers reliable single-side installation without the need for access to the opposite side, providing a strong M5 internal thread in thin materials. The 90° countersunk head ensures a flush finish and improved load distribution, reducing the risk of pull-through and improving the appearance of assembled panels. Its compact body dimensions make it suitable for restricted installation spaces while maintaining consistent clamping performance.

How to use

Drill or countersink the hole to the appropriate diameter for a 90° countersunk rivet nut, insert the rivet nut from the accessible side, and use a blind rivet nut installation tool to set the nut until the body collapses and clamps the sheet. Verify that the head sits flush in the countersunk bore and that the M5 thread is fully formed and free of debris before installing the mating fastener. Follow the installation tool manufacturer's guidelines for mandrel selection and setting force to ensure correct installation.

Recommendations

For consistent results, use a calibrated blind rivet nut tool suitable for M5 rivet nuts and confirm hole diameter and countersink angle before installation. For dissimilar materials or high-load applications, consider appropriate corrosion protection and validate joint strength with a sample assembly.
