When a washer or nut is identified as 1/2”, this is the
Nominal size, meaning the inside diameter is 1/2 inch; if a
second number is present it represent the threads per inch
When bolt or capscrew is identified as 1/2 - 16 x 2”, this
means the Nominal size, or body diameter is 1/2 inch; the
second number represents the threads per inch (16 in this
example, and the final number is the body length of the
bolt or screw (in this example 2 inches long).
