4.2.3 MOUNTING HARDWARE AND FASTENER TORQUE RECOMMENDATIONS

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

val

ues 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.
