Part # THFE-M8-15ZI, 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 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.

¹ The “L” dimension is the height of the installed stud at max grip. The height of the stud will increase if it is installed into thinner material. To calculate “actual L” use this formula: max grip - actual grip + L = “actual L”
² Threads are gageable to within 2 pitches of the “S” Max. dimension. A class 3B/5H maximum material commercial nut shall pass up to the “S” Max. dimension.
³ To minimize sheet distortion and maximize product performance, use a centerline-to-edge value greater or equal to the value specified.
