NOT STANDARD BIMETALLIC THREADED STUD WITH A REDUCED SHAFT
Type RD-DUO / BR-DUO
The threaded stud type RD-DUO/BR-DUO consists of two different materials. It is threaded almost to the top of the welding tip which is reduced to about the core diameter of the thread. Thus the fillet diameter will only be slightly (0,5-1 mm) bigger than the external diameter of the thread.
