The Evolution of Bolted Joint Design: An Analysis of VDI 2230 (2021)
For bolts screwed into soft materials (e.g., aluminum $\le 200$ MPa tensile strength), VDI 2230:2021 mandates a minimum engagement length $m = 2.0 \times d$ for coarse threads and $1.8 \times d$ for fine threads, unless a thread stripping check proves otherwise. vdi 2230 2021

The guideline is built around a structured 13-step calculation procedure (steps R0 to R13) designed to determine the required bolt dimensions while accounting for numerous influencing factors: The guideline is built around a structured 13-step
