Description

Stainless Steel Self Drilling screws can drill their own pilot hole due to their design which incorporates a special point similar to a drill bit. Our stainless steel self-drilling screws are ideal for a range of sheet metal material including Aluminium, Aluzinc and Galvanised steel.

Our range of material includes 304 (A2) and also a lower cost option of 410 (1.4006) stainless or most impressively our innovative 304(A2) Bi-Metal option with hardened drilling point. This screws can be used for up to two sheets of 1.00mm stainless steel (2.00mm total thickness). The hardened point cuts through the steel then the 304 screws are designed to last a long time without corrosion and can also be used with 316 sheet or cladding. This is a much better option than either a carbon steel screw or a 410 stainless screw that will be at risk of corrosion. The screws are coated with a silver coat that improves the performance by acting as a lubricant during application.

The Bi-metal screw drills (1), shapes the thread (2) and tightened (3) all in one process saving time and delivering a long lasting solution that has revolutionised metal fabrication across Europe.

Some screws can be supplied with and without our silver slide coating, on their own or with washers polyamide or EPDM bonded. The head types are Hexagon, Hexagon slotted, pan head Philips or pan head square slot (bit included). Self-drilling screws may also be refered to as tek screws, roofing screws or stitching screws.

These screws can also be supplied coloured either powder coated or liquid (paint) coated for colour matching purposes subject to minimum quantaties.

Size range - Diameters start at 3.9mm up to 6.3mm

Lengths - Starting at 12mm up to 50mm

All our screws re subject to extensive quality control procedures and testing to include the following

  • Dimensional check
  • Drill and screw in test
  • Tensile strength and shearing resistance
  • Extraction resistance and pull through
  • Torsional strength
  • Hardness and coating thickness
  • Torque test
  • Kesternich test SO2 to ISO 3231 (accelerated corrosion test)
  • Cross cut test (ISO 2409)
