For more than 40 years, we have focussed on the manufacture of welding studs for tip ignition and short cycle. All threaded studs for tip ignition are produced to DIN EN ISO 13918. Intermediate lengths or modified length tolerances can be produced on request according to a drawing or diagram. The flanges can be standard or miniature right through to custom sizes.

The thread tolerance class can also be changed to "6e", "6f" or "6h".
