Ensure that the combined tensile and torsional stresses generated during assembly do not exceed the yield strength limit of the bolt material (typically capped at 90% of Rp0.2cap R sub p 0.2 end-sub Step 10: Verify Working Stress ( σBmaxsigma sub cap B m a x end-sub
The guideline is structured for cylindrical bolted joints with standard metric threads (ISO 262), where the bolt strength is at least ISO 8.8 or higher. Part 1 was last revised in February 2015 (the current active version as of this writing), with a new edition expected to incorporate updates from ISO/TC 2 fasteners.
VDI 2230 Part 1 is the globally recognized standard for the systematic calculation of high-duty bolted joints. It provides a standardized multi-step procedure to ensure that a bolted connection can safely transmit working loads while maintaining its integrity.

It helps engineers optimize bolt sizes, reducing material weight and production costs.
), which accounts for variations in friction and tool tolerances (e.g., impact wrenches vs. hydraulic tensioning). The engineer must calculate the maximum required assembly preload ( FM,maxcap F sub cap M comma m a x end-sub ) to guarantee the minimum necessary clamp force ( FM,mincap F sub cap M comma m i n end-sub ) is achieved. 5. Stress Verifications Finally, the standard requires several safety checks: Ensure that the combined tensile and torsional stresses
