Application
• Fastening of cable trays, pipes on a horizontal cantilever support, fastened on a
vertical structure
• Support is fastened by two X-BT-MF (horizontal distance x)
• L1 is the distance of the load center to the center of the fasteners
• Load F is the acceptable total load (all dead load including)
Boundary conditions
• These values are ONLY reflecting capacity of X-BT-MF threaded stud. Structural
analysis of support / structure is NOT in Hilti scope. See the detailed statements in
disclaimer — 2018/05/04
• Shear load fully carried by one X-BT-MF (worst-case)
• Load F acting at the distance of L1 from structure surface
NOTE: load capacity used for calculation N
rec
= 340 lb (axial) / V
rec
= 500 lb (shear)
Technical assessment — maximum of L1 and F (depending on load F or lever arm length L1 and X-BT-MF distance x)
