Hex Head Bolt Fastening Hardware
The Crouse-Hinds Aircraft Guidance Sign features a number of hex head bolts preassembled by
the OEM. In order to properly fasten and unfasten these bolts, should maintenance be necessary,
the following hardware is needed:
Equipment
Socket Sizes (mm)
Square Drive Sockets
8, 10, 17, and 19
Open End (or Combination) Wrenches
8, 10, 17, and 19
*For M5, M6, M10, and M12 Bolts
Table 3. Recommended Socket and Wrench Sizes
Calibrated Torque Wrenches
A calibrated torque wrench is required in order to torque the bolts to the appropriate value after
fastening them with the socket wrench. Calibrated torque wrenches should also be used for
periodic torque checks. The torque values for hardware are listed in
Table 18, pg 91
. The
necessary torque wrenches and the recommended manufacturer are listed below:
We recommend a calibrated torque wrench (micrometer adjustable solid audible/tactile “click”
impulse when torque value attained with an accuracy of +/- 4%).
Our recommended metric torque wrenches: Sturtevant Richmont P/N 810775, range 4 to 20 Nm
and P/N 810777, range 20-100 Nm. Suggested English torque wrenches: Sturtevant Richmont
P/N 810750, range from 30 to 150 in-lb or equal, and Sturtevant Richmont P/N 810748, range
from 100 to 600 in-lb. Certificate of calibration included with suggested torque wrenches.
