Steel, strength class 10.9, zinc-nickel, transparent (P3E) anti-friction coating

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 through preliminary testing



GEFU (with strength class 10.9), nominal diameter ≥ M6 => see art. 0209 82... with zinc flake coating
