Tightening torque will vary, even with the same bolting material (e.g. steel), accord­ ing to the surface finish. Torque is greatly reduced when the bolt and nut start turning together. 5) Socket play Torque is lowered as the six-sided configu­ ration of the socket of the wrong size is used to tighten a bolt. 6) Switch (Variable speed control trigger) Torque is lowered if the unit is used with the switch not fully depressed. 7) Effect of Connecting Adaptor The tightening torque will be lowered through the use of a universal joint or a connecting adaptor.
