Bolt and nut combinations need to be "stretched" in order to
provide a clamp effect across the joint.
"Bolt Torquing" stretches the bolt as the nut is turned by a
wrench. The more the nut is turned, the further it rides up
the bolt's threads. Since it can't extend into the joint,
the nut "pulls" the bolt, thus "stretching" it.
"Bolt Tensioning" uses a tensioning tool to pull the bolt
until the required stretch has been achieved. The nut is
then turned freely by hand until it rests against the joint
face. The tensioning pressure is then released. The applied
stretch is retained mechanically by the nut.
Since friction has an effect on how easily a nut can be
turned against a joint's face when torqued, "Torquing" is
much less accurate than "Tensioning" (in which friction is
moot).
