The type IS internally threaded stud is designed specifically for short-cycle welding (SC). It creates a permanent threaded fastening point on sheet metal without drilling or access to the reverse side of the component.
It is ideal for applications requiring a subsequent threaded connection, such as fastening components, brackets, housings or decorative elements to thin and medium-gauge sheet metal.
Main technical specifications
- Welding process: Short cycle – no shielding gas or ceramic ferrule required.
- Reference standard: DIN EN ISO 13918 (type IS)
- Available threads: M3, M4, M5 and M6 (other sizes on request)
- Standard materials:
- Copper-plated grade 4.8 steel (4–8 µm electrolytic copper finish)
- A2-50 stainless steel
- Weldability: Excellent
- Typical applications: Thin to medium-gauge sheet metal (0.8–3 mm)
