NOTES
1. These torque values are to be used for all hardware
excluding: locknuts, self-tapping screws, thread forming
screws, sheet metal screws and socket head setscrews.
2. Recommended seating torque values for locknuts:
a. for prevailing torque locknuts - use 65% of grade 5
torques.
b. for flange whizlock nuts and screws - use 135% of
grade 5 torques.
3. Unless otherwise noted on assembly drawings, all torque
values must meet this specification.

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