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).
