Self Drilling Screws
Self Drilling Screws or Tek Screws enable the assembler to quickly attach materials such as steel, aluminium, composites or timber to steel section, or similar, up to 35mm thickness without the need for any pre-drilling or thread tapping. Each screw features a special cutting tip and tapping thread the design of which varies depending on the material that is being screwed into.
Increasingly relied upon in modern construction projects where their speed and efficiency of use considerably reduce labour costs.
We offer the full range of high performance self drilling screws with different material types.
Where a higher level of corrosion resistance is required the Stainless Steel 304 or 316 bi-metal variant provides a stainless fastener with a high performance non-stainless cutting tip. Though costly, this option offers the best of both worlds: a stainless tek screw capable of drilling through depths of steel up to 20mm.
A lower cost zinc plated option is available where corrosion resistance is not a priority, such as for internal ducting and metal framing applications.
The standard DIN 7504 in different head types and materials, including stainless steel, are available for light duty applications where the high performance of the Evolution range is not required.
