Combining the features of Bright Zinc and Dacromet range of Self Drilling Screws, Welfast Double Thread Self Drilling Screws are engineered to fasten insulated roofing panels, composite panels and insulated cladding to steel purlins and wood structures. These screws are available in Coarse and Fine Thread options in Dacromet coatings.

Engineered to consistent performance and speed, Welfast Self Drilling Screws offer quality with precision. These are cold formed with rolled thread for superior strength and fast drilling performance. Strictly adhering to DIN Standards, Welfast Self Drilling Screws are available in a dynamic assembly of diameter ranging from #10 - #12 with length ranging from 20mm 100mm. Additional options of Coarse Thread and Fine Thread adds value to selection.

Drywall Screw is a specialized self-tapping screw with a cylindrical shaft. These screws almost always have a Phillips Bulge Head rather than a slotted head, which provides additional control for installers. In addition of a standard drill, installers also use a tool known as a drywall dimpler, which has an adjustable nose to install a drywall screw without tearing the paper on each sheet.
A standard drywall screw can be readily identified by its black finish. This black coloring comes from a phosphate mineral coating that is applied to these screws. This coating helps to minimize rusting and corrosion as the screws are exposed to wet joint compound or paint.
