The Complete Guide to DIN 76-A: Thread Undercuts for External Threads

Modern CAD software, such as SOLIDWORKS, Autodesk Inventor, and Siemens NX, includes features to automatically add a DIN 76 thread undercut to a model. When creating a threaded shaft or a blind tapped hole, you can often select "DIN 76" or "DIN 76 Form A" from a library of standard features. The software will then prompt you to select the thread size (e.g., M10 x 1.5), and it will automatically apply the correct x and g2 dimensions, saving you from having to calculate or look them up manually.
