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, (distance between threads). The final number
is the body length of the bolt or screw, 2 inches (50mm).
