DRILLER® screws for metal sheet stitching & photovoltaic panels assembling
DRILLER® WKTF are self-tapping screws that ensure stable and solid construction fixing into roof surface. WKTF screws are especially recommended for mounting photovoltaic panels and other installations on roofs with steel sheet cladding. Special thread geometry provides tight connection between materials and enables high load bearing capacity.
The innovative tapered thread minimizes screw slippage on the metal sheet surface and reduces assembly time. The chipless assembly eliminates metal chips, which cause corrosion centres. On request, we deliver screws with steel or stainless EPDM washer assembled.
