Hex Nut

Standard Hardware Sizing

When a washer or nut is identified as 1/2”, this is the Nominal size, meaning the inside diameter is 1/2 inch; if a second number is present it represent the threads per inch

When bolt or capscrew is identified as 1/2 - 16 x 2”, this means the Nominal size, or body diameter is 1/2 inch; the second number represents the threads per inch (16 in this example, and the final number is the body length of the bolt or screw (in this example 2 inches long).

The guides and ruler furnished below are designed to help you select the appropriate hardware and tools.

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.
