Standard Hardware Sizing

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).

The guides and ruler furnished below are designed to help you select the appropriate hardware and tools.
