About Screw, nut, and washer sizes
Numeric screw sizes start with a number indicating the diameter such as #4, #6, #10, etc (lower numbers
are smaller) followed by the number of threads per inch (32, 40 etc), then the length. For example: 4-
40 x 3/16 is a #4 screw with 40 threads per inch and a length of 3/16". Nut sizes are the same except
they do not have a length. Spacers are like nuts but have a length. Washers simply have the # size and
no threads per inch or length. Star washers have small teeth to prevent slipping.
