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).
