Trapezoidal Thread Norms – DIN Norms

In the table below, you will find the required dimensions for designing your trapezoidal threaded components. The parameters d2, D2, d4, d3, and d1 locate in the drawing on the right side of the table.

You can also get a pre-finished 3D model of your desired thread size by clicking the “3D-Modell” button on the last column. Once you have determined your desired thread size, send us your screw and nuts inquiries.

If you are unsure about the best thread size for your application, try our online dimensioning tool.
