Standard Hardware Sizing
Lockwasher
Carriage Bolt
When a washer or nut is identified as 1/2” (M8), this is
the Nominal size, meaning the inside diameter is 1/2 inch
metric thread diameter); if a second number is present
Hex Nut
(8mm
it represents the threads per inch (distance between threads).
Wrench & Fastener Size Guide
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).
