Sirius 11mm Bi-Hex Roofing Cladding Teks Screws Plastic Head Type Driver

The Sirius 11mm Bi-Hex Roofing Cladding Tek Screw Driver Adaptor is a specialist tool designed for installing plastic-capped cladding and roofing screws on commercial buildings. This non-magnetic driver adaptor ensures secure, damage-free fastening when working with colour-matched tek screws, making it essential for professional roofers and cladding contractors.

The 11mm bi-hex profile is specifically engineered to fit cladding and roofing tek screws with moulded plastic caps. Unlike standard magnetic drivers, this adaptor features an internal circlip that physically grips the screw head, providing positive retention during positioning and driving. This is particularly valuable when working overhead or at awkward angles where gravity would otherwise cause screws to drop.

The non-magnetic design prevents interference with coated fixings, ensuring clean installation without marking or damaging decorative heads. The 1/4" hex shank offers universal compatibility with all 18V cordless drill drivers, impact drivers, and mains-powered machines, fitting both quick-chuck systems and standard 3-jaw chucks.

Ideal applications include metal roofing installation, composite cladding systems, industrial and commercial building envelope work, agricultural building sheeting, and warehouse and factory roofing projects. The circlip retention and precise bi-hex fit ensure every fixing is driven cleanly and securely, protecting expensive colour-matched fixings from damage.
