  • Through hole magnetic mounting pad
  • Pencil
  • Cordless drill driver
  • Drill bit
  • Screwdriver bit
  • Two flat head screws with either a 4mm (0.16″) or 5mm (0.2″) gauge (shank diameter)

Step 1 – Place magnet on material

Place the magnet with the back plate facing downwards onto the piece of material you wish to attach it to.

Step 2 – Mark out magnet

Using a pencil, mark a line down each of the two shortest sides of the through hole magnetic mounting pad.

Next, mark out the two through holes onto your piece of material. Remove the through hole magnetic mounting pad from the material.

Step 3 – Drill pilot hole

Drill a pilot hole into the material on the two markings indicating the through holes.

Use a drill bit which is 3mm (0.12″) or 4mm (0.16″) in diameter to match the size of the screw. This helps to prevent the material from splitting whilst still giving the screws threads something to attach themselves to.

Step 4 – Place magnet on material

Place the through hole magnetic mounting pad back onto the material, with the back plate facing downwards, directly onto the markings to ensure it is in the right position.

Step 5 – Attach screws

Using a cordless screwdriver, drive the two screws through the magnetic mounting pad’s through holes and into the pilot holes.

The screws need to be driven into the material until the screw head touches the back plate. The magnet should now be unable to move without any gaps between the magnetic mounting pad and the non-ferromagnetic material.
