STANDARD PARTIAL THREADED STUD
Type PD / PF
The threaded stud type PD has a partial thread. The diameter of the unthreaded stud section on the welding tip corresponds to the pitch diameter of the thread. Thus the diameter of the weld-fillet is approximately 3-4 mm larger than the external diameter of the thread. The maximum load is identical to the load of a 4.8 screw.
