Blind rivet nut GESIPA St M8x11x20 for 3.0–6.0 mm sheet, pack of 100

GESIPA blind rivet nut St M8x11x20 for 3.0–6.0 mm sheet, pack of 100 is a steel threaded insert engineered to form a reliable M8 female thread in sheet materials with thickness from 3.0 to 6.0 mm. Designed for blind installation where only one side of the workpiece is accessible, the rivet nut expands and clamps to the sheet, providing a durable, load-bearing thread for bolts, studs or other fasteners. Supplied in a pack of 100, these rivet nuts are intended for production runs, repair jobs and maintenance tasks where consistent thread quality and repeatable installation are required.

Advantages

These blind rivet nuts deliver a permanently formed internal M8 thread without the need for tapping from the opposite side, saving time and allowing installation in confined assemblies. Made of steel, they provide good strength and resistance to deformation under torque, ensuring secure fastening of components. The packaged quantity of 100 supports efficient workflow and reduces handling time on repetitive assembly operations. Their design ensures consistent clamp and load distribution across the sheet material.

Key specifications

How to use

Drill or punch an appropriately sized hole in the sheet material according to the rivet nut manufacturer’s hole size recommendation. Insert the blind rivet nut into the prepared hole from the accessible side. Use a compatible blind rivet nut setting tool or rivet gun with the correct M8 mandrel to pull the rivet nut, causing the back end to expand and clamp against the sheet. Once the rivet nut is fully set, remove the tool and check that the insert presents a flush or slightly protruding head as required. You can then install an M8 bolt, stud or fastener into the newly formed thread to secure components.

Recommendations

For reliable results, ensure hole diameter and sheet thickness match the rivet nut specification, use the correct setting tool and mandrel for M8 installation, and verify thread engagement after installation. Where corrosion resistance is required, consider appropriate surface treatments or material choices for mating fasteners and the surrounding environment.
