The draw stud with washer serves to connect a round sheet metal punch with a hydraulic drive. On the punch side it has an M10×1 thread, while the connection to the drive is formed by a 3/4-16 UNF thread. The total length of the stud is 88 mm. Type 2 version is intended for round punches with a diameter of 16.5 to 32 mm. When selecting a replacement, both connecting threads must match, not just the required hole diameter.
