Mechanical and functional properties in accordance with DIN 7500-1 (shape PE), case-hardened (-O-) zinc-plated steel, blue passivated (A2K) with slide coating, head dimensions according to ISO 14583

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.

Notice

The suitability of the GEFU
^® for the application or component in question must be determined by testing in advance. Guideline values for suitable hole diameters are specified in DIN 7500-2.
