Blind Rivet GESIPA 6310478 Steel/Steel 4×12 mm flat head for 6.5–8.5 mm

Blind rivet GESIPA 6310478 is a one-sided mechanical fastener with a steel body and steel mandrel, featuring a flat head sized 4×12 mm. It is designed for installation where access is available from only one side of the joined components and is suitable for use in metal assemblies and compatible substrates. The rivet is intended for creating permanent, vibration-resistant joints in applications with hole or material thicknesses of 6.5–8.5 mm.

Advantages

This blind rivet delivers a reliable, permanent connection that resists loosening under vibration thanks to its steel construction. The flat head provides a low-profile finish on the visible side, improving contact area and load distribution. Its design permits installation from one side, simplifying assembly in confined or inaccessible locations and reducing installation time when compared with two-sided fastening methods.

How to use

Drill or prepare a hole that matches the rivet head and grip range, ensuring clean edges and correct diameter for a snug fit. Insert the rivet through the aligned parts so the head sits flush against the visible surface. Use an appropriate blind rivet tool sized for steel mandrels to pull the mandrel until the rivet body deforms and clamps the materials together; the mandrel will break off at the designed break point. Verify the formed blind side is properly compressed against the workpiece and that the head is seated evenly on the visible surface.

Recommendations

For best results, select a rivet hole diameter that matches the rivet dimensions and use a rivet gun rated for steel mandrels. When joining dissimilar materials, consider galvanic compatibility and, if necessary, apply protective coatings or isolation layers to prevent corrosion. Inspect installed rivets for proper set and tightness, and avoid overloading the joint beyond the mechanical capabilities of steel fasteners.
