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.
Common Hardware Types
Hex Head Capscrew
Washer
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).
