2 studs
4 studs
Application
• Fastening of lamps, signals, sensors on inclined cantilever support, fastened
on a vertical structure
• Support is fastened by two / four X-BT-MR (vertical distance x)
• L1 is the distance of the load center (~middle of the load) to the vertical
structure surface
• Load F is the acceptable total load (all dead load including)
Boundary conditions
• These values are ONLY reflecting capacity of X-BT-MR 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 / two top X-BT-MR (worst-case)
• Load F acting at the distance of L1 from structure surface
