These roofing screws are fitted with a washer, ensuring the screw will fit snugly against the roofing sheet, allowing for maximum fixing and a water tight seal.

Roof Zip 12 gauge x 50mm Class 4 Tek roofing screws for fixing into timber or steel. 

Winds can create considerable forces on both the upper surface and the underside of metal roofs. To ensure roofs are secure, our 12 x 50 Class 4 screws are recommended for fixing pierced metal sheeting to timber or metal battens.  Self-drilling hex head fasteners with neoprene sealing washers are manufactured from high tensile steel with Colorbond durable coatings.  Roofing screws should be driven through the square with the surface of the sheeting to provide a complete seal around the screw hole.   

Please do not over-tighten the Tek screws, as this can damage the sealing washer and roof sheeting. The ends of corrugated roofing and close-pitched trapezoidal roofing sheets should be fixed through the side lap and every second crest after that.

Fixings are intermediate purlins or battens, for corrugated metal roofing should be through the side lap and the third and seventh corrugation from the side lap. For close-pitch trapezoidal roofing sheets, fixings should be at every third rib.

A string line should be used to make out a straight line along the centre of the battens or purlins.
