Counterboring is really one of the simplest things to do to hide the head of a screw. Sometimes people also use counterboring to let a short screw reach through a thick board. All you need to counterbore a screw is a drill.
- Step 1: You must first make a pilot hole for the screw. This is the hole that the length of the screw will fit down. Make sure to compensate for how far down the counterboring will be.
- Step 2: Change the drill head to one that will create a hole wide enough for the screw head to fit into.
- Step 3: Drill the larger hole right over the middle of the first until it is deep enough. Make sure you aren’t going too far through the first bit of material.
- Step 4: Put in the screw down into the pilot hole and drill it in.
If you want to hide the screw put a plug into the hole. You could also fill it with putty or plaster if you won't need to remove the screw.
When to Use Counterboring
Counterboring is sometimes used to make furniture. For example, an entertainment center needs to have large screws in place to support all of the weight on the shelves. By using counterboring, the screws can be hidden out of sight.
