screw sizes
When it comes to screw sizes, The Shed still tends to think in the old Imperial system, in which a 6-gauge screw was an extra-skinny one; an 8g was a good all-rounder; and a 10g was as fat as any DIY job was likely to need.
But ordering online has required a mental re-adjustment, with a huge creaking of gears, to thinking in millimetres, and the following reminder lists might be helpful to Shed readers …
width
3mm of shank diameter = old-fashioned 4 gauge
3.5 mm = 6g
4 mm = 8g
5 mm = 10g
6 mm = 12g
length
12 mm = ½ inch
16 mm = 5/8 inch
20 mm = ¾ inch
40 mm = 1 ½ inch
50 mm = 2 inch
