Double Ended Screw DIN939, also known as DIN939 stud bolts or thick-stem stud bolts, are high-strength fasteners widely used in mechanical engineering, construction, shipbuilding and other fields. According to the DIN939 standard, the dimensions and specifications of Double Ended Screw DIN939 are strictly standardized. This ensures that bolts produced by different manufacturers are interchangeable, which facilitates user selection and procurement. The shank of the DIN939 stud bolt is thicker, usually b1=1.25d (d is the nominal diameter of the thread). This design enhances its ability to withstand tensile and shear forces. DIN939 stud bolts can be processed and customized according to user needs, such as changing the length, thread specifications, etc., to meet the needs of different application scenarios.
