When tightening a bolt or nut, the applied torque must overcome the thread friction, the friction under the bolt head or nut and the inclined plane of the thread, to obtain a bolt preload (see Fig. 1A). While untightening, provided that the assembly remains in the same condition, the ap...
Torque is a measure of rotational or "twisting" force. Measuring torque while installing a bolt prevents the overtightening of bolts. Torque wrenches are the most commonly used measures for this torque. They measure the torque applied to the fastener as the wrench tightens the bolt. In the ear...

Bolts constitute a very important subset of mechanical fasteners. In order to tighten bolts, a degree of bolt preload scatter is to be expected. Since the torque control of tightening bolts is the most popular means of controlling the preload, an appropriate tightening torque becomes pivotal. ...

To overcome the two problems the company's engineers re-assessed the basis on which they determined the bolt's tightening torque and the resulting clamp force. Briefly; they deduced that a higher strength grade of bolt was required. It was decided to use M12 strength grade 10.9 bolts, flange...

Through a large number of tightening data statistics, the bolts near the minimum dynamic torque monitored by the bolt tightening equipment are found to measure the bolt length. Compared with the bolt length before the experiment, it can be determined whether the axial tightening force of the bolt...
