Appendix B Common Hardware Application Guidelines
Use the information below and on the following pages to
identify proper fastening techniques when no specific
reference for reassembly is made.
Bolt/Screw Length: When bolt/screw length is not given,
use Figure 1 as a guide. As a general rule, a minimum
length of one thread beyond the nut and a maximum
length of 1/2 the bolt/screw diameter beyond the nut is
the preferred method.
Washers and Nuts: Use split lock washers as a bolt
locking device where specified. Use SAE flat washers
with whiz nuts, spiralock nuts, or standard nuts and
preloading (torque) of the bolt in all other applications.
See Appendix C, General Torque Specifications, and
other torque specifications in the service literature.

Steps for common hardware application:
1. Determine entry hole type: round or slotted.
2. Determine exit hole type: fixed female thread
(weld nut), round, or slotted.
For round and slotted exit holes, determine if
hardware is greater than 1/2 inch in diameter, or
1/2 inch in diameter or less. Hardware that is
greater than 1/2 inch in diameter takes a standard
nut and SAE washer. Hardware 1/2 inch or less in
diameter can take a properly torqued whiz nut or
spiralock nut. See Figure 2.
3. Follow these SAE washer rules after determining
exit hole type:
a. Always use a washer between hardware and a
slot.
b. Always use a washer under a nut (see 2 above
for exception).
c. Use a washer under a bolt when the female
thread is fixed (weld nut).
4. Refer to Figure 2, which depicts the preceding
hardware configuration possibilities.
