Blind rivet nut GESIPA M5, steel, flange size 7×11.5 mm

Blind rivet nut GESIPA M5 in steel with a flange size of 7×11.5 mm is a fastener designed to form a reliable internal M5 thread in thin or hollow materials where access is available only from one side. The part is intended for use in sheet metal, profiles and assemblies, offering a compact flange that distributes load and facilitates blind-side installation. Steel construction provides mechanical strength and typical corrosion resistance of steel fasteners when used with appropriate surface treatments or coatings.

Advantages

The rivet nut enables installation of an internal M5 thread without the need for nut access behind the component, reducing assembly time and simplifying repairs. Its 7×11.5 mm flange ensures improved bearing surface and load distribution compared with smaller flanged inserts. Made of steel, the rivet nut delivers higher shear and tensile strength than most non-ferrous alternatives, providing secure connections in structural and load-bearing assemblies. The blind installation process is straightforward and repeatable with standard blind-riveting tools and nosepieces sized for M5.

Suitable for

• Sheet metal fastening where only one-side access is available
• Assembly of profiles and frames requiring internal M5 threads
• Repair and maintenance work on housings, panels and enclosures
• Industrial and light structural applications needing strong, compact threaded inserts

Key specifications

• Thread size: M5 internal thread
• Material: steel
• Flange dimensions: 7 × 11.5 mm
• Installation type: blind (one-side) installation
• Typical application thickness range: designed for use in thin sheet and hollow sections (verify with tool and material)

How to use

Drill the correct hole diameter for the specified flange size and material thickness, then insert the blind rivet nut into the hole from the accessible side. Use a compatible blind-rivet nut tool or setting mandrel suitable for M5 to expand the nut body on the blind side until the flange is firmly seated against the workpiece. After setting, remove the tool and check that the internal M5 thread is clean; a pass of a thread chaser or tap may be used if necessary for burr removal. Install the mating M5 bolt or screw to complete the connection.

Usage recommendations

Select drill sizes and tool nosepieces that match the flange dimensions and material type to ensure correct swaging. For corrosion-critical applications, consider compatible coatings or stainless-steel alternatives and verify torque values for the M5 thread in the given substrate. Perform a trial installation on scrap material to confirm fit and setting parameters before series assembly.
