Hardware Identification & Torque Specifications
Common Hardware Types
Standard Hardware Sizing
When a washer or nut is identified as IQ", this is the
Nominal size, meaning the inside diameter is II2 inch; if a
second number is present it represent the threadsperinch
When bolt or capscrew is identified as 112 - 16 x 2", this
means the Nominal size, or body diameter is l/2 inch; the
second number represents the threadsperinch
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.

1. These torque values are to be used for all hardware
excluding: locknuts, self-tapping screws, thread forming
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.
