Description

Drilling a clearance hole and countersink

Clearance hole ensures a tight joint, allowing the screw to pass freely through

the top board. The screw engages only the bottom board. Hence, the upper

board is pulled down to the bottom board.

Countersink is needed to set screws flush or below the surface of the board!
