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

Saves money



Non-cutting thread formation



Large thread flank overlap


High load-bearing capacity



Strain-hardened receiving thread (nut thread)


Greater load-bearing capacity



Play-free and self-locking thread seating
