Standard Hardware Sizing

When a washer or nut is identified as 1/2” (M8), this is the Nominal size, meaning the inside diameter is 1/2 inch (8mm metric thread diameter); if a second number is present it represents the threads per inch (distance between threads).

When bolt or capscrew is identified as 1/2 - 16 x 2” (M8 - 1.25 x 50 ), this means the Nominal size, or body diameter is 1/2 inch (8mm metric thread diameter), the second number,16, represents the threads per inch, (1.25 thread diameter). The final number is the body length of the bolt or screw, 2 inches (50mm).
