The Sealey TIRM5 Threaded Insert is designed for DIY enthusiasts, automotive mechanics, and fabricators who require a reliable and permanent threaded fixing point in sheet metal or thin-walled materials. These M5 rivet nuts offer a secure, vibration-resistant attachment point for machine screws, making them ideal for assembly and repair work. While they are highly durable, it is important to note that a dedicated rivet nut installation tool is required to expand the insert properly, as they cannot be set using standard hand tools.

These inserts have a standard M5 x 0.8mm metric thread.
No, you must use a dedicated rivet nut installation tool or an adapter designed for threaded inserts.
These inserts are designed for material thicknesses between 0.5mm and 2mm.
The zinc plating offers good corrosion resistance, but they are best suited for indoor or sheltered automotive environments.
They are made of durable zinc-plated steel.
Each pack contains 50 individual M5 threaded inserts.
The drill hole is likely too large; ensure you are using the correct bit size for the M5 insert specification.
Verify that the bolt matches the M5 x 0.8mm thread pitch and ensure no debris has entered the insert during installation.
Check that the installation tool's mandrel is fully tightened and that the material thickness falls within the 0.5-2mm range.
To install these inserts, first drill a hole in your workpiece that matches the outer diameter of the rivet nut shank. Insert the TIRM5 into the hole and use a compatible rivet nut installation tool to pull the threaded mandrel, which collapses the insert against the back of the metal surface. Ensure the material thickness is strictly between 0.5mm and 2mm for the best results; if the material is too thin, the insert may spin, and if it is too thick, it will not properly grip the surface. While the zinc plating is resistant to moisture, avoid using these in high-salinity or harsh chemical environments without additional protective coatings.
