Installation Typicals - Fastening on Steel Threaded Studs

Application
• Fastening of junction boxes, switches on a vertical structure
• Element is fastened by X-ST-GR
Boundary conditions
• These values are ONLY reflecting capacity of X-ST-GR threaded stud.
Structural analysis of support / structure is NOT in Hilti scope. See the detailed
