The primary goal of a VDI 2230 calculation is to determine the required bolt dimensions while accounting for critical factors like:
Detailed methodologies are provided for calculating stresses in bolts and the joined parts, as well as assessing their strength under various load conditions.

VDI 2230 Part 1 has undergone several revisions. Key editions include:
VDI 2230 Part 1 outlines a structured, 13-step calculation process to verify a bolted joint design. Below is a simplified summary of these steps: Step 1: Determine the Dimensions and Geometry Calculating Compliance ( δBdelta sub cap B δPdelta
Many engineering firms build parameterized spreadsheets embedded with the standard’s complex geometric equations.
) of the bolt material (typically restricted to 90% of yield). Step 9: Verify the Maximum Bolt Stress During Operation
Select an initial bolt size and strength class (e.g., grade 8.8, 10.9, or 12.12) based on the rough magnitude of the loads. Step 4: Calculate Elastic Resiliences ( δBdelta sub cap B δMdelta sub cap M
Check for Bolt Stress : Ensure the bolt does not yield under assembly and operating loads.
