• Enlarged head diameter reduces stress on panel.
  • Thicker head allows for larger hole in attached panels.
  • Clinch design provides high-strength in sheets as thin as 0.8 mm.
  • Recommended for use in steel or aluminum sheets HRB (Rockwell “B” Scale) 85 or less and HB (Hardness Brinell) 165 or less.
