Torque values listed are for general use only. Check tightness of fasteners periodically. Relative Strength Marking 4. Caution: All material included in this chart is advisory only, and its use by anyone is voluntary. In developing this information, Fastenal has made a determined .
Standard tightening torque for metric screw threads. Or for metric sizes: M = P x D. P = bolt tension Newtons. These formulae may be used for bolts outside the range of the . The tightening torque values given in the above table serve only as a guide.
This bulletin covers the following Champion . Suggested Starting Values.
The torque figures quoted have been based on a theoretical bolt load equal to of the proof load of. The following torque values are to be used on all fasteners unless otherwise. STAInlESS STEEl CAP SCREWS. The maximum recommended tightening torque values stated above are for bigHead products under stand-alone test conditions. Maximum permissible torque . Recommended Assembly Torques.
Bolt torque values are calculated by using . Nm, based on a friction coefficient of 0. (more…)
