For example, an ANSI Inch 1/2″ flat head screw with a normal fit countersunk hole will require a pilot hole diameter of 9/16″, a countersunk diameter of 1″, and a countersunk angle of 82°. WebThe gauge (imperial) is half the imperial diameter (in 16th of an inch) of the screw head, roughly. The precise relationship of imperial screw head sizes and the gauge can be calculated. The formula is as follows: (Head diameter in sixteenths is an inch X 2 ) – 2 = Gauge. E.g. 5/16 head times two equals 10, minus two equals 8. The Gauge is 8.
