Thread-rolling screws form a nut thread in cast blind holes, transition points, drilled, lasered and punched sheet metal parts. Unlike thread cutting, with thread-rolling, the structure of the material is not interrupted in the counter thread but rather displaced and strain-hardened.



Eliminates thread-cutting


Saves on costs



Non-cutting thread formation



TRILOBULAR shape of the screw combined with the radius profile of the thread flanks


  • Low tapping torque with greater flank coverage by the thread

High clamping force



Large thread flank coverage


High load-bearing capacity



Strain-hardened counter thread (nut thread)


Greater load-bearing capacity



Play-free and self-locking seating of the thread


  • Reduced likelihood of screw working loose

Protection against loss



The formed thread constitutes a "metric" standard thread
