Experimentelle und rechnerisch validierte Methode zur Bestimmung der Mindesteinschraubtiefe von Schraubenverbindungen mit gefurchtem Mutterngewinde Experimental and computationally validated approach for determining the minimum length of thread engagement for bolted joints with formed female threads

open access: yesMaterialwissenschaft und Werkstofftechnik, Volume 56, Issue 2, Page 305-315, February 2025.
A new approach to estimate the minimum length of thread engagement for bolted joints with formed female threads has been verified for different thread sizes and geometries. Depending on the size of the pre‐drilled pilot hole the pull‐out strength was investigated experimentally to confirm the analytical calculation approach developed.
