Strength values and thermal expansion coefficients for various steel grades and lightweight materials (like aluminum used in modern automotive designs) were synchronized with current international standards.
In a world where machine safety and structural integrity can never be taken for granted, VDI 2230 2021 is not just a guideline. It is the definitive engineering standard that ensures when a bolt is tightened, it stays tightened — for the life of the machine. vdi 2230 2021
The initial preload is not permanent. Two primary effects cause a reduction in the clamping force over time: vdi 2230 2021
