DIN 7500-1 cylinder head, case-hardened (-O-) galvanised steel, blue passivated (A2K)

Thread-rolling screws form a nut thread in cast blind holes, rim holes and drilled, lasered and punched sheet metal parts. Unlike thread cutting, thread-rolling does not interrupt the material structure in the receiving thread. Instead, the material is displaced and strain-hardened.



Eliminates thread cutting


Cost savings



Non-cutting thread formation



Large thread flank overlap


High load-bearing capacity



Strain-hardened counter thread (nut thread)


Greater load-bearing capacity



Play-free and self-locking thread seating


  • Reduced likelihood of screw working loose

Retention mechanism



The formed thread corresponds to a standard metric thread
