Designed for professionals and DIY enthusiasts alike, the AB Tools 8mm (M8) Nut Serts are the ideal solution for creating robust, permanent threaded fixing points on metallic or dense materials where traditional tapping or welding is impractical. These zinc-coated steel inserts provide exceptional structural integrity and vibration resistance, though they do require a specific rivet nut installation tool for proper deployment.

These are primarily designed for metallic or dense materials. They may not provide sufficient grip in soft plastics.
Yes, a rivet nut setting tool is required to correctly deform the insert behind the material.
These are M8 (8mm) thread diameter inserts.
No, they are designed to be a permanent, semi-captive fastener once installed.
Yes, they are zinc-coated to prevent rust and wear in standard workshop and automotive environments.
The hole is likely too large. Use a drill bit that matches the required diameter specified by your tool manual for an 8mm insert.
Ensure the installation tool is perfectly perpendicular to the workpiece during the actuation process.
Check the thread for burrs or debris, or ensure the insert was not over-compressed, which can slightly deform the internal thread.
For successful installation, you will need a dedicated M8 rivet nut setter. Start by ensuring the base material is free of debris. Drill your hole, insert the nut sert, and use the tool to collapse the insert until firm resistance is felt. Because these are steel, they are highly durable, but avoid over-tightening with a pneumatic tool, as this can potentially strip the threads. To maintain them, keep them in a dry environment to ensure the zinc coating remains intact, though they are naturally resistant to common workshop humidity.
