Description

Stainless Steel Bi-Metal Self Drilling screws (Tek screws) can drill through stainless steel sheet due to their innovative design which incorporates a special point similar to a drill bit made from hardened carbon steel. The rest of the screws is manufactured from stainless steel 304 (A2) then the whole screw is protected with a silver slide coat.

This coating not only adds additional corrosion protection it also reduces the screw in resistance. 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 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.

Screws can be supplied with and without washers both 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 referred 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 quantities.

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

Lengths – Starting at 12mm up to 50mm

All our Bi-Metallic 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)
