Where Evoshield® Screws Are Used
Roof & Wall Cladding
Profiled metal sheeting lives or dies by its fixings. Evoshield® hex head TEK® screws — unwashered or with 16mm bonded EPDM sealing washers — fix roof and wall sheeting to light section (TEK® 3, 1.2–4.0mm) or heavy section steel (TEK® 5, 4.0–12.0mm) in a single self-drilling operation. The EvoShield® coating is salt-spray tested to 500 hours, keeping fixings performing for the life of the cladding. Washered stitching screws complete the job on side laps, end laps and flashings.
Composite & Insulated Panels
Evoshield® composite panel fasteners carry a high thread under the head that grips the outer skin while the main thread anchors into the purlin, clamping insulated sandwich panels from 80mm up to 300mm without crushing the core. Available for light and heavy section steel with 12mm, 16mm or 19mm galvanised sealing washer options, plus SuperTEK® versions with 1,000-hour coating for heavy structural supports and gash point versions for timber purlins.
Timber to Steel
Evoshield® wing drill TEK® screws fix timber battens, boards and ply through to steel with a flush countersunk finish — the wings ream a clearance hole through the timber, then shear off at the steel face so the hardened drill point can pull the timber down tight. Available in Phillips and Torx drive for light section rails and heavy section beams, in lengths up to 180mm for thick timber build-ups.
Metal Framing & Drylining
Low profile pan head and wafer head Evoshield® screws fasten stud-and-track framing, angle and channel without creating a bump behind the board, keeping plasterboard sitting flush. Phillips and Torx drive options self-drill light gauge steel up to 3.5mm with no pre-drilling, speeding up frame assembly on site — with collated versions available for high-volume drywall framing work.
