THFE-0420-20ZI
Heavy Duty Studs for Thin Sheets – Type THFE
THFE-0420-20ZI
Heavy Duty Studs for Thin Sheets – Type THFE
- 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 .031”.
- Recommended for use in steel or aluminum sheets HRB (Rockwell “B” Scale) 85 or less and HB (Hardness Brinell) 165 or less.
