NOT STANDARD THREADED STUDS
Type MD / BN fileté
The threaded stud type MD corresponds to the threaded studs MPF and PD, but is threaded almost to the top of the welding tip. Thus after welding the stud is threaded up to the weld-fillet. 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.
