A drilling screw, also known as a self-drilling screw or teks, is a screw with a drilling tip, specially designed to be screwed into metals such as aluminium and steel without pre-drilling. In addition, our drilling screws can be fitted with a pre-mounted washer. Thanks to these features, pre-drilling is not necessary, and in combination with a pre-mounted sealing ring, this ensures considerable cost savings during assembly and a watertight seal! As a specialist in fasteners, Archey also offers hardened stainless steel screws. For more information, contact our sales team.
