FIX-IT Self drilling screw of metal sheet roof manufactured in accordance to the international standard AS3566. This is the standard production screw. Used for steel roofs that are recognized around the world. Which will determine the size of the screws, the drill head, the pitch, screw degrees, corrosion resistance in environmental applications. And suitable for use with steel metal roof
FIX-IT made from AISI 1022% C low carbon steel grade 0.18-0.23 through a hydrogen-impregnated dip-impregnation into the steel, then form a hydried compound, which causes the brittle screws to crack easily. FIX-IT has a hardness value of less than 500 on the outside and Vickers Hardness on the screw core is no more than 400.
