Hide cabinet screwholes

When you screw two cupboards together, there’s an easy way to hide the screw holes. Find where the hinge plates for the cupboard doors will be attached. Drill a hole in the middle of these areas and drive in your joining screws. Then install the hinge plates over the top.

Step by Step Instructions

1 Attach the sides of the 300mm base cabinet to the base panel
2 Attach the back to the 300mm base cabinet
3 Attach the top rail to the 300mm base cabinet
4 Attach the plastic feet to the bottom of the kitchen cabinet
5 Adjust the height of the feet
  • Step 1. Attach the sides of the 300mm base cabinet to the base panel

    Put the first side panel into place and line up the pre-drilled holes. Use an impact driver to gently drive the screws into place. When the first side is on, turn the cabinet over and do the same on the other side. Check to see if the joining edges have properly lined up. If not, tap them lightly into place with a rubber mallet and then tighten the screws.
  • Step 2. Attach the back to the 300mm base cabinet

    Put the back panel into place and line up the pre-drilled holes. Screw the back and both side panels together, then turn the cabinet upside down and do the base panel. Once again, check your edges are properly lined up and use the rubber mallet to tap them into place before you give your screws a final tighten.
  • Step 3. Attach the top rail to the 300mm base cabinet

    Put the top rail into position. Push all four screws into place with your thumb to temporarily hold the rail in place. Then drive the screws in and use the rubber mallet again to tap the edges into place before giving the screws a final tighten.
  • Step 4. Attach the plastic feet to the bottom of the kitchen cabinet

    The plastic feet for your kitchen cabinets come in four parts – base plate, tube, screw thread and foot. Attach the base plate to the base of the cabinet, using the pre-drilled holes and the short screws. Push the tubes into the base plates and the feet onto the screw threads. Then drive the screw threads into the tubes.
  • Step 5. Adjust the height of the feet

    You can adjust the height of your feet by screwing the threads in or out. This is very useful if your floor isn’t level. Use a combination square to help set the height of all the feet at 145mm. Then put the cabinet in place and adjust the feet if you need to level it up on an uneven floor.

Health & Safety

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
