Fischer double thread screw for photovoltaic installations M12x350mm 00570113

STSR is the double-threaded A2 stainless steel screw for fastening substructures for photovoltaic systems on corrugated or faux-roofing slabs with wooden supporting structure.

 

Also suitable for installation on concrete with chemical anchor or on lateral-cement with chemical anchor and FIS HK mesh anchors or FIS HN sock anchors. Integrated EPDM gasket for sealing against rain infiltration. Requires pre-drilling.


 

Suitable for Corrugated sheet roofing system with:
 

• Solar-light profile
• Solar-fish profile
  
   

Fixing STSR double-threaded screw:

• With FIS V chemical anchor on concrete beams and slabs
• With FIS V chemical anchor and FIS HK mesh dowel on concrete floor slabs
• Directly on wooden beams after drilling the guide hole
  
   

Applications:

• Concrete beams and slabs
• Engineered concrete slab
• Wooden joists
  
   

Assembly:

• Identify the length of the STSR double-threaded screw according to the thickness of the supporting structure
• Define the spacing of STSR double-threaded screws according to the snow and wind loads of the installation area of the system and roof pitch
• Locate the position of STSR double-threaded screws according to the supporting structure and plant layout
• Drill the support according to the diameter of the screw and the type of support
• Attach the STSR double-threaded screw to the structure by bringing the EPDM rubber into contact with the cover
• Tighten the MU F flange nut on the gasket to maintain the watertight seal
• Attach the SSP or MW connection plate, adjusting its height using the MU F nuts
