Steps

1. Prepare the Components

   • Mark the center hole for the insert screw.

   • Bore a 12 mm (15/32 in) perpendicular hole. For hardwoods, slightly increase bore size to 12.5–13 mm and apply wax for easier threading.

2. Install the Insert Screw

   • Drive in the insert screw using an 8 mm hex bit or Allen key.

   • Ensure it sits flush or slightly below the surface.

3. Drill the Railing or Mating Component

   • Bore holes according to the specified diameters and distances.

   • Depending on material thickness, connectors may be set deeper into the wood.

4. Insert the Screw Shaft

   • Thread the screw shaft into the insert screw counterclockwise until secure.

5. Assemble the Joint

   • Push the two components together until aligned.

6. Tighten the Connection

   • Place the gear housing onto the screw shaft thread.

   • Tighten using a 5 mm hex bit in a power drill or manual driver.

   • Optional: Plug the 25 mm (1 in) access hole after assembly.

Tips

• Avoid using an impact driver to prevent damage to the gear housing.

• For maximum strength, use with dowels and adhesives during assembly.

• Ensure alignment before final tightening to prevent joint stress.
