Suggested torque values
Daniels Manufacturing Corp takes no responsibility for the suggested torque
values stated on this page. They were obtained from members of SAE
Technical Standards Committee (AE-8C1, Connectors and Accessories), and
will be published in a technical standard which is under development in the
committee. If you need more information, contact DMC for the latest status on
the ARP***** Torque for Wiring System Components Standard.
Torque values used to assemble connectors,
backshells, and other wiring system
components are the responsibility of the
user/installer to determine the best torque
range for the application. It is also the
responsibility of the user/installer to select
the appropriate tool for the work and the
user conditions/environment.

CAUTION: Over tightening (Torque)
connectors, backshells, and other wiring
system components can damage threads,
metal or composite structure, or rubber
components, and cause them to fail.
Under-tightening (Torque) wiring system
components can cause the components to
loosen during use and fail.
Tightening or loosening system components
beyond the specified range of a torque
wrench may damage a torque wrench, and
affect its accuracy and repeatability.
NOTE: For additional information about torque
calculation, see page 36.
