Choosing the Right Countersink
How to Choose The Right Size Countersink by Diameter
A simple rule of thumb is to choose a countersink which is 50% larger than the diameter of the hole
Countersink diameter = 1.5 x bolt size (hole) diameter
Ex: For a 1/4-20 bolt, multiply the diameter (.250) x 1.5 = .375. This equates to a 3/8” countersink
How to Choose The Right Size Countersink by Angle
Angle is based on the screw or bolt type being used
82º is most common
