GEFU^® thread-rolling screw With Taptite 2000^® thread, countersunk head and hexalobular drive

Self-tapping screws form a nut thread in cast blind holes, rim holes and 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.

• Cost savings

Eliminates thread cutting

• Non-cutting thread formation

• Low rolling torques with greater thread flank overlap

TRILOBULAR shape of the core diameter combined with the radius profile of the thread flanks

• High clamping force due to low rolling torques

• High load-bearing capacity due to large flank overlap of thread and strain-hardened counter thread (nut thread)

• Protection against loss (reduced likelihood of screw working loose)

Play-free and self-locking thread seating

• The formed thread corresponds to a standard metric thread

Where necessary, the GEFU screw can be replaced with a metric screw
