RUKO Shop Blog — Countersinks

A flush flat surface can create a nice affect within your material/workpiece. To keep the screw heads or nuts flush requires a process called Countersinking.

It is not uncommon to find screw heads that have been incorrectly placed, causing them to stick out from the surface. Not only is this unsightly, but the protruding screw heads can also be dangerous, as it can result in a severe cut or scratches. Additionally, if these screws can't be tightened all the way, items may get caught on the head of the screw. Countersinking your hole before inserting the screw is one way to avoid this problem in the future.
