Hardware Identification & Torque Specifications
The guides and ruler furnished below are designed to help you select the appropriate hardware.
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).

| 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. | ||||||
