Stepped Threaded Rod Stud Assembly with Shoulder Stud and Long Externally Threaded Shaft

Precision jigs, fixture locating pins, and robotic end-effectors use a shoulder stud where shoulder diameter tolerance and thread class together determine locating repeatability and clamp load distribution; shoulder OD above tolerance prevents the stud from entering its bushing, while thread engagement shorter than specification reduces clamp axial force and allows the assembly to shift under lateral vibration. Suzhou Dazhi Intelligent Manufacturing Technology (Suzhou, Jiangsu) Swiss-machines and turns this stainless steel shoulder stud with long externally threaded shaft using Swiss machining, turning, and external cylindrical grinding at their facility (in excess of 4,000 m²), with shoulder OD, thread class, and overall length confirmed per your drawing during in-process inspection. Dazhi's Suzhou facility specialises in non-standard automation parts, aerospace components, and medical parts for aerospace, automation, medical equipment, and OEM manufacturing shoulder stud applications. To quote, we need your drawing showing shoulder diameter, thread specification, shaft length, and stainless grade. For costed feedback from our suzhou production team. Applications cover automotive, military, and robotics.
