It includes the specific input parameters, the intermediate result of each step and the final safety factors, tying the theory of the previous 7 articles into one executable calculation chain. https://mechcalc.net/blog/en/posts/vdi2230-06-preload-design-r1-r6/ Mon, 20 Apr 2026 16:00:00 +0200 https://mechcalc.net/blog/en/posts/vdi2230-06-preload-design-r1-r6/ The upper half of the VDI 2230 calculation chain R1–R6 explained: the tightening factor αA, the three sources of the minimum clamping force FKerf, the choice of force-ratio Φ formula, preload loss (embedding + thermal expansion), and the derivation of the minimum and maximum assembly preload. https://mechcalc.net/blog/en/posts/bolt-preselection-01-load-to-size/ Thu, 26 Mar 2026 20:58:00 +0100 https://mechcalc.net/blog/en/posts/bolt-preselection-01-load-to-size/ For a given working load, how large should the bolt be? This article covers the preliminary design and pre-selection of bolts: first read the nominal diameter and property class from a quick pre-selection table by load range, then use the Kübler equation to back out the thread stress cross-section from the axial working load and the required clamping force, combined with the tightening factor, reduction factor and simplified fatigue and bearing-pressure checks, to help engineers quickly size a bolt in the early design stage.
