2.2.4 MOUNTING HARDWARE AND FASTENER TORQUE RECOMMENDATIONS
The Table E provides you with guidelines to refer to when determining torque values for clean and dry fasteners.
Keep in mind, however, that several variables can influence the “optimum” torque to be used in a given situation,
and Table E should be used only as a general reference. If you are unsure of the proper torque values to use, consult
the machine manufacturer for specific recommendations.
• Use quality alloy steel fasteners (SAE Grade 8, ISO property grade 10.9).
• If the fastener threads are lubricated, reduce the torque amount. Use a torque value that is 70 percent
of that listed in Table E. For example, if you are using a lubricated 1/2-13NC base stud on a SC-1T
transducer, reduce the torque amount of 45 ft-lb to 31 ft-lb.
• Transducers operated at lower forces may not require the higher clamping forces obtained at the cited
torque values.

Mechanisms used for industrial automation can tax even the best threaded fasteners. You can improve
the likelihood that bolts and shafts remain secure by using suitable anaerobic “thread lockers” during
the final assembly.
