GX® Self-Extruding Screws



The screw extrudes thin sheet metal in vertical directions during assembly. This creates an increased area for thread engagement and a strong joint. The under-head feature effectively cuts through point and other coatings providing a grounding effect that meets U.L. requirements. The scraped paint collects and seals around the grounding ring to protect the unfinished surface and inhibit corrosion.

  • Increased area for thread engagement
  • Paint and coating removal
  • Combine several assembly steps into one

  • Hurricane- underhead feature can be added to absorb torque during the drive and provide a locking feature to the screw
