AbolishedButtress threads with 3 and 30 degrees flank angle--General plan
锯齿形(3°，30°)螺纹 直径与螺距系列
Application Summary AI generated
This standard specifies the diameter and pitch series for buttress threads with a 3-degree load flank angle and a 30-degree clearance flank angle. It is applied in mechanical engineering for designing and manufacturing threaded components that must withstand high axial loads in one direction, such as in presses, jacks, and heavy machinery. The standard ensures interchangeability and compatibility of these specialized threads in industrial equipment and mechanical systems.
