Blind rivet nut GESIPA M8, 11×17 mm body, for 0.25–3.5 mm steel, flat round head

Blind rivet nut GESIPA M8 with an 11×17 mm body and flat round head creates a permanent internal M8 thread in steel sheets where access is available from one side only. It is designed for sheet thicknesses from 0.25 to 3.5 mm and provides a compact, low-profile fastening point that resists loosening under vibration when installed correctly. The flat round head distributes load on the sheet surface and the rivet nut’s geometry ensures reliable seating in thin steel panels for panel assemblies, frames and repair work.

Advantages

This blind rivet nut offers a one-sided installation process that saves time on assemblies where back access is impossible. Its 11×17 mm body and flat round head produce stable clamping and even load distribution, reducing the risk of pull-out in thin sheet metal. The design is compatible with common installation tools for blind rivet nuts and delivers a consistent internal M8 thread for standard bolts and screws, enabling repeatable maintenance and component replacement.

Key specifications

How to use

Drill a hole of the recommended diameter for the 11×17 mm rivet nut body into the steel sheet, ensuring hole edges are clean and free of burrs. Insert the rivet nut from the accessible side and use a compatible blind rivet nut setting tool or rivet nut gun to compress the body until the nut forms a secure bulge behind the sheet. Verify that the flat round head sits evenly on the sheet surface and that the installed part provides a full M8 thread by screwing in a test bolt. If required, apply appropriate torque values for the mating fastener according to the assembly specification.

Recommendations

Use rivet nuts made of materials compatible with the base steel and environment to minimize galvanic corrosion. Select the correct drill diameter and tool setting for the 11×17 mm body to ensure reliable clamp and tensile performance. For repetitive production work, use a calibrated, purpose-built rivet nut installation tool and check installed threads periodically during maintenance.
