What Size Drill Bit For Blue Wall Plugs. Wall plugs are the most commonly used type of fixing device, they are simple to use and give good results with a simple. I provide a wall plug colour chart for quick.
Depends on what the wall is made of. Buy a bulk pack of the commonly used sizes. A drill bit half a mm smaller helps keep things tight.
