Straight Cylindrical Stud With Partially Threaded Stud and External Helical Threads

Thread pitch diameter tolerance and unthreaded shank diameter together govern the function of a partially threaded stud with external helical threads; pitch diameter outside 6g tolerance causes either binding with the mating nut below minimum engagement or reduced bearing area and pull-out strength below the design load, while shank diameter variation above ±0.02 mm changes the clearance fit in the mating hole and shifts lateral positioning accuracy in precision assembly applications for drones, medical devices, and energy storage hardware. Foshan Zhengshang Precision Hardware (Foshan, Guangdong, ISO 9001, ISO 14001, ISO 45001 certified) turns this straight cylindrical partially threaded stud at their just over 2,500 m² Foshan facility using Swiss machining and milling & turning, with thread pitch diameter, shank diameter, and thread run-out length confirmed against your released print during first-piece check. Zhengshang serves automotive, medical equipment, drones, energy storage, and fastener partially threaded stud applications. To quote, we need your drawing showing thread class, shank diameter, run-out length, and material. And we will return a pricing from our foshan facility, supporting communication, fasteners, and toys and gifts industry projects.
