): This is a safety margin for friction. If you use a basic torque wrench, this factor is higher (around 1.6), meaning you need a larger bolt to compensate for inaccuracy. 4. How to Access the PDF
This step determines the necessary minimum clamp load (FMmin) that the bolted joint must provide after assembly. This load is dictated by the requirements of the application, such as:

Remember: Bolted joints are the most common, yet most misunderstood, machine element. VDI 2230 Part 1 turns guessing into engineering.
If you are working with high-stress fasteners, obtaining a licensed copy of the VDI 2230 Part 1 PDF through official standards organizations (such as DIN or VDI) is a foundational step toward robust, safe, and reliable product development.
