Installation

• It is recommended to insert the screw at an angle of 30-45 degrees to the exposed face on the tongue side, and start where the tongue and face intersect. This will drive the screw throught the board and out into the substrate
• Make sure the head of the screw sits beneath the tongue so that it does not interfere with the next board
• For a secure fix it is advised to insert a screw every 300mm (minimum)
• If inserting a screw 50mm from the end of the board we recommend that you pre-drill to eliminate splitting
