how are screws measured

UK Screw Sizes – Imperial vs. Metric. There is something of a divide throughout the UK between those who use the metric system for measurements, and those who prefer to stick with imperial equivalents. Metric screw sizes provide a diameter and length in mm. Imperial screw sizes provide a gauge size and a length in inches.

Example: 5/8 x 2 = a shoulder screw with a 5/8 diameter shoulder, 2 long. Thread size is one standard size smaller than the shoulder diameter and needn’t be specified, except for: A screw with a 1/2 diameter shoulder has a 3/8 – 16 thread.

Screws. If the head is countersunk, then you measure from the top of the screw to the bottom. Countersunk screws end up being level with the surface material you are screwing them into.
