The load factor φ determines what proportion of the external axial working load FA is actually carried by the bolt as additional bolt force FSA = φ·FA, and what proportion is absorbed by the clamped parts FPA = (1‑φ)·FA. This represents a fundamental insight of VDI 2230 — that the stiffness relationship between bolt and joint members determines how loads are distributed.

The guideline aims to optimize joint design by calculating the precise relationships between forces, moments, and deformations. According to experts at Bossard , its primary benefits include:
