Installation Typicals - Fastening on Steel Threaded Studs

S-BT-MR / S-BT-MF • Metric
S-BT TECHNICAL DATA USED FOR THE
FOLLOWING CALCULATIONS
S-BT technical data
• Drill hole type / base material: Pilot hole, t
II
≥ 6 mm (0.24") or drill through hole, 5 mm (0.20") ≤ t
II
< 6 mm (0.24")
• Base material: Steel S235 / A36 (higher steel strength is possible, increases the rec. load)
• Recommended interaction for combined load: N
rec
= 1.8 kN (axial) / V
rec
= 2.6 kN (shear)
V-N (shear and tension)
