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 represents the
threads per inch.
When a 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 (2 inches long in this example).
The guides and ruler furnished below are designed to
help you select the appropriate hardware and tools.
