Do you need to pre drill Tek screws?
Each Tek screw features a carving piece on its tip, which is what makes self-drilling possible. This means you don’t need to create a pilot hole before the fastener, and it also means your work moves forward efficiently.
Do Tek screws rust?
Tek screws are made from high-grade, anti-corrosive material that can withstand rust and corrosion.
Do you need to predrill Tek screws?

How thick steel can Tek screws be used for?
These tek screws are commonly used in the roofing industry for fixings roofing sheets and cladding to metal substrates. They can also be used for light duty metal to metal fixing. The drill point on these will drill through 3.5mm steel, and it is important that you do not use these for anything thicker than 3.5mm.
What screws are best for outdoor use?
Some of the best screw materials include:
- Zinc Wood Screws. – More prone to rust unless coated or galvanized. – Different grades are available.
- Stainless Steel Wood Screws. – Ideal for standard outdoor use for a variety of applications.
- Silicon Bronze Screws. – Very resistant to water corrosion.
- Decking Screws.
What are Tek 5 screws used for?
This is why TEK 5 screws are used for fastening into structural steel. As a general rule of thumb, the higher the TEK number (the longer the drill point), the thicker the metal. It is fundamental that the point is high enough on the TEK scale to pierce the metal being drilled into.
What size TEK screw do I need?
Typically, stitching screws are 6.3mm diameter (equivalent to 14g), whereas standard tek screws are 5.5mm (equivalent to 12g). A 16mm EPDM washer is supplied with each screw, and it provides a water tight fixture for use in roofing applications.
Do you need an impact driver for TEK screws?
