Lengths range from 1/4″ to 6″; 5″ or so is the longest typically found and larger screw sizes are offered in the longer lengths. Sizes less than 1″ are in 1/8″ increments; lengths from 1″ to 3″ are in 1/4″ steps; and screws longer than 3″ increase in length by 1/2″.
What are standard screw sizes?
The main difference between 10-32 and 12-24 threads is their dimensions. 10-32 screws have a diameter of 3/16″ (4.8mm) where as 12-24 screws have a diameter of 7/32″ (5.6mm). M6 threads are 6mm in diameter, only . 4 mm larger than 12-24 screws.
