Trapezoidal threaded screw
grabcad
A two-start M22x3 trapezoidal threaded screw is available in various formats such as STEP, IGES, Sldprt (2013), and parasolid. If you wish to alter the dimensions of this screw, you can use the part calculation tool after waiting for some time. However, if your PC is powerful enough, you may not need to wait.
