This bolt torque calculator will ensure that you tighten up your bolts with the correct torque. Just as well, as a loose bolt can really ruin your day. Read on to discover what is bolt torque, the bolt tightening torque calculation formula, how to calculate bolt torque, and typical torque...
The widely recognized engineering formula, T= K x D x P (to be explained later in this article), was used to provide the chart's values, but it must be understood that every bolted joint is unique and the optimum tightening torque should be determined for each application by careful exper...

By applying the three-dimensional FEM, the relationship between the tightening force F and the tightening torque T was clarified by varying the pitch difference alpha during the whole nut tightening/untightening process. The well-known F-T formula available for tightening the normal nut (alpha = ...
Torque has been converted into ft/lbs by dividing the result of the formula by 12. All calculations are for Coarse Thread Series (UNC). Grade 2 calculations only cover fasteners 1/4" - 3/4" in diameter up to 6" long. For longer fasteners, the torque is reduced significantly. ...
Combined with expert reasoning, the zero-point torque value of the seal ring is estimated online. Abasolo M [12] proposed an optimization method of tightening sequence based on finite element, and calculated the force applied to each bolt. Finally, at the end of the sequence, a relatively ...
