The E-8 is our standard 22.5 kN power tool for setting rivnuts (M3 to M8) in all materials. It is simple to use and easy to set up. This quick guide shows how to set a typical standard rivnut into metal. A YouTube video is now available on the Scell-it ‘Know How’ channel here.
1. Check tool battery is powered up.
Ensure the tool battery has at least two indicator battery lights. The E8 comes with a standard Element One rechargeable battery and recharging unit.
2. Ensure the mandrel on the tool matches with the rivnut size.
To remove the mandrel:
Remove battery. Unscrew and remove the Anvil and Locknut unit. Pull back the tensile sleeve and unscrew the mandrel.
To fit a mandrel:
Pull back the tensile sleeve and screw in the mandrel. Screw the anvil and locknut unit back on.
Note: it is recommended to grease the mandrel before use in order to prevent premature wear.
3. Set the stroke.
Turn the stroke setting nut to set the stroke number scale from 0 (min) to 9 (max).
It is recommended to start at 2 and perform tests until correct scale is achieved.
4. Load the Rivnut
- Screw the rivnut onto the mandrel until just one thread is showing.
- Tighten the anvil and locknut
- Loosen rivnut so it is engaged by about 2 threads.
- Push rivnut back on to load the tool.
5. Set the rivnut
Insert the rivnut through the installation hole – ensuring it is level and square.
Press the trigger to set the rivnut and slowly pull back on the tool to enable the release of the tool.
Check the rivnut has set correctly and obtained the desired deformation (see chart).
If more or less stroke is required then adjust stroke setting nut and reset rivnut (step 4).
