GEFU^® thread-rolling screw With Taptite 2000^® thread, cylinder 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.

Benefits:

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 thread flank overlap


• Due to 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.
