Products

For a number of years Buildex has been the leading Australian manufacturer of Stainless Steel Taptites and Type 17 screws. Recently, it has released a new range of Stainless Steel Teks® self-drilling screws for roofing and cladding applications.

This new range leads the way again, with the innovation of robotically welding a martensitic drill tips to its 300 Teks. This hardened tip provides the drill performance benefits of a carbon steel tip, while providing higher corrosion protection. It allows the grade 305 body of the screw to secure materials being fastened with a more ductile grade of stainless steel.

How to Use

Measure the total thickness of the materials to be fastened.
Choose a Stainless Tek® screw long enough to fasten the material being secured to.
Choose the correct driver for the screw being used. Fit the driver to a 550 Watt power screw driver and set tool to no higher than 2500rpm.
Push sharply to create a starting point.
Drive screw home and maintain firm end load pressure until screw has drilled and fastened.
