Double-threaded screw for fastening photovoltaic systems on roofs with a steel load-bearing structure covered by corrugated panels, faux panels or tiles.
Stud screw STSI A2
STSI is the double-threaded screw in A2 stainless steel for PV panels mounting on roofs with a steel load-bearing structure covered by corrugated panels, faux panels or tiles. Incorporated EPDM gasket for sealing against rain infiltration. Pre-drilling required.
The STSI double-threaded screw is supplied pre-assembled with EPDM gasket and pair of nuts for connection to the MW or SSP brackets.
The roofing must not be removed during installation.
Thanks to the EPDM gasket, waterproofness of the roof is maintained.

Functionality
Determine the centre distance of the STSI double-threaded screws according to the snow and wind loads of the system installation area and inclination of the roof.
Identify the position of the STSI double-threaded screws depending on the load-bearing structure and the layout of the installation.
Drill the support according to the diameter of the screw.
Tighten the STSI double-threaded screw until the gasket is fully in contact with the roof covering.
Carefully seal the exit point of the screw from the roof with bituminous sealant in order to improve waterproofness.
Connect the Solar rail to the upper part of the screw by inserting SSP or MW connection plates, adjusting their height using the MU nuts.
