FAQs

What is the grip range for these inserts?

These M8 inserts are designed for materials with a thickness between 0.5mm and 3.5mm.

Do I need a special tool to install these?

Yes, a rivet nut setting tool (or nutsetter) is required to properly swage the insert into the workpiece.

Can these be used in wood?

These are designed for metal and plastic sheet applications; they generally do not provide sufficient grip in soft wood.

Are these rust-resistant?

Yes, they feature a zinc-plated finish which provides a good level of resistance to corrosion in standard environments.

What size hole should I drill for these?

Always refer to the rivet nut tool instructions, but generally, an M8 rivet nut requires a drill hole slightly larger than the diameter of the insert body.

Troubleshooting

Insert spins inside the hole during installation

The pilot hole was likely drilled too large. Ensure the hole diameter matches the rivet nut specifications perfectly.

Insert does not compress properly

Check that the tool stroke adjustment is correct for an M8 insert; if the tool is set for a smaller size, it may not apply enough pressure.

Threads appear damaged after installation

Ensure the installation tool mandrel is fully threaded into the insert before beginning the compression cycle to prevent cross-threading.

Pros and Cons

Pros

  • Durable zinc-plated finish resists rust and wear
  • Provides a strong, permanent thread in thin sheet metal
  • Easy to install with a standard rivet nut setting tool
  • Bulk pack size is cost-effective for frequent users

Cons

  • Requires a specific rivet nut tool for installation
  • Not suitable for materials thicker than 3.5mm
  • Cannot be removed easily once swaged/installed

Setup, Compatibility & Care

To install these inserts, you must first drill a hole of the appropriate diameter (check your tool's manual for M8 hole sizing requirements) into the workpiece. Thread the rivet nut onto the mandrel of your installation tool. Insert it through the pre-drilled hole, operate the tool to compress the nut until it is securely locked against the rear surface, and then unscrew the tool mandrel. Ensure the surface is free of burrs after drilling to ensure the flange sits flush. Store these in a dry environment to maintain the integrity of the zinc coating.
