A distorted thread grips the screw to resist loosening. Also known as Heli-Coil inserts, these inserts have coils that expand once installed to securely anchor the insert. All have a prong for ease of installation. An installation tool grips the prong and reduces the coil diameter, enabling the insert to fit in tapped holes.

Also known as Fastite screws, these offer more thread engagement in 0.028" to 0.063" thick sheets to prevent overtightening and damaging threads. They're made from steel and have a zinc plating to resist corrosion in wet environments. Length is measured from under the head.

The tool includes nosepiece assemblies to install M4, M5, M6, and M8 rivet nuts (additional sizes sold separately). To use, thread the nut onto the included mandrel and press the trigger to spin the nut onto the tool. Place the nut into the material and press the trigger to install the nut. Press the trigger one more time to spin the mandrel off.
