Self Drilling Screw

The self-tapping self-drilling screw is a mechanical fastener with an integrated drill tip and self-tapping threads, enabling simultaneous drilling and threading into metal sheets and profiles. Diameter ranges from 3 to 10 mm, with lengths from 12 to 150 mm. Made from hardened carbon steel or stainless steel A2/A4, tensile strength ranges from 500–800 MPa. The screw head can be Phillips, hex, or slotted, allowing fast installation with manual or power tools. Galvanized, epoxy, or chrome surface coating increases corrosion and wear resistance.

The drill tip, angled 60–90 degrees, allows drilling without pre-holes. Threads are precisely designed for strong and uniform connections in steel sheets 0.5–6 mm thick. Common applications include metal structures, warehouses, sandwich panels, and industrial profiles. Optimized mechanical design and protective coating extend service life and reduce maintenance requirements.

wafer head self drilling screw

The pan head self-drilling screw is an integrated fastener with a drill tip for simultaneous drilling and fastening into metal and sheets. Diameter ranges from 3 to 8 mm, with lengths between 12 and 150 mm. Made from carbon steel with heat treatment or stainless steel A2/A4, tensile strength ranges from 500–800 MPa. The rounded pan head, with DIN 7504 standard and Phillips or hex drive, allows rapid installation using manual or power tools. Surface coating with galvanization or paint increases corrosion and wear resistance.

The drill tip, angled 60–90 degrees, enables drilling without pre-holes. Threads are precisely designed for secure connections in steel sheets from 0.5 to 6 mm. Common applications include metal structures, industrial equipment, sandwich panels, and light profiles. Mechanical design and corrosion-resistant coating extend service life and ensure fast, reliable installation.
