What is a #6 screw?
A 6 gauge screw will have a head almost equal to 6 mm wide. Gauge= (Head diameter in sixteenths of an inch X 2 ) – 2. E.g. 5/16 head times two equals 10, minus two equals 8. The Gauge is 8. The above formula means that for imperial gauge, the diameter in mm is almost half the gauge.
