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 high 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 can be replaced with a metric screw.
Notice

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