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.

Wrench & Fastener Size Guide
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.
