Atul Fasteners, CLIMASHIELD Self Drilling Screws are designed to provide excellent corrosion and weathering resistance. These Screws are specially suited for outdoor building and construction Industries.
The principle of Galvanic protection by using dissmiliar metals in contact, where one will corrode to protect the other is employed to give protection from corrosion. Zine-Tin compound are mechanically deposited on screws which give good porosity density rating of 8 and eliminate the risk of hydrogen embrittlement associated with electro-plating the Zinc on to the screws.
