Torque Wrench
is the general name for a hand-guided screwing tool, and used to precisely set the force of a fastening such as a nut or bolt. It allows the operator to measure the rotational force (torque) applied to the bolt so it can be matched to the specifications.
To obtain a leak-free flange connection, a proper gasket installation is needed, the bolts must be assign on the correct bolt tension, and the total bolt strength must be evenly divided over the whole flange face. With Torque Tightening (the application of preload to a fastener by the turning of the fastener's nut) the correct bolt tension can be realized. Correct tightening of a bolt means making the best use of the bolt's elastic properties. To work well, a bolt must behave just like a spring. In operation, the tightening process exerts an axial pre-load tension on the bolt. This tension load is of course equal and opposite to the compression force applied on the assembled components. It can be referred to as the "tightening load" or "tension load"
