Pull studs are an important link between machine and tool. The requirements concerning accuracy, rigidity and reliability are very high.
Pull studs of minor quality not only decrease the performance of the machine, they are even a safety risk. A breaking pull stud might cause severe damage on machine and workpiece and even injuries on persons.

– Made of special steel with high rigidity
– Costly heat treatment in several steps
– Spots with highest stress tempered specifically
– High impact strength
– All functional surfaces fine finished after hardening
– Highest security and reliability
