We offer a comprehensive range of screw production equipment—including cold heading, thread rolling, and assembly machines—alongside full-specification drilling tail screws, supported by ODM, OEM, and non-standard customization services.
YWC Self Drilling Screws, also known as Tek screws, integrate a hardened drill tip to drill, tap and fasten in one step without pre-drilling. Our lineup covers hex washer head, wafer head, pan head, countersunk head and truss head, with Phillips or Torx anti-slip drive, #2 / #3 drill points and optional EPDM sealing washers. Available in carbon steel, 410 and 304 stainless steel, finished with zinc plating or color-painted coating. These self drilling screws deliver high torsion, strong pull-out resistance and reliable waterproof performance, widely adopted for metal roofing, steel cladding, light gauge steel framing and sheet metal fabrication. Custom sizes and bulk export packing are supported.
Self Drilling Screws are one-step drilling & tapping fasteners for metal-to-metal and metal-to-wood connections. Multiple head styles, drill-point sizes and anti-rust surface treatments are in stock. Stainless steel and hardened carbon steel options offer excellent durability and corrosion resistance. Roofing-type self drilling screws are assembled with rubber washers for waterproof sealing. Suitable for metal roof sheets, wall cladding, light steel structures and HVAC duct installation. OEM specifications and large-volume export supply available.
