FAQs
What is the correct screw size for my project?
Choose the screw length based on the combined thickness of the timber and steel you are joining. Ensure the screw is long enough to provide a secure grip in the steel.

Are these screws suitable for outdoor use?
Yes, the screws are zinc plated and have an Elementech coating for superior anti-corrosion, making them suitable for outdoor applications.
How do the breakaway wings work?
The breakaway wings create a clearance hole in the timber, then break off when they come into contact with the metal surface being drilled, engaging the thread with the metal.
What is the salt spray test rating?
The screws have been salt spray tested to 1,000 hours, indicating a high level of corrosion resistance.
Troubleshooting
Screw is not drilling into the steel.
Ensure you are applying sufficient pressure and using a drill with adequate power. Check that the steel thickness is within the screw's specifications (1.5mm to 4mm).
Screw head is stripping.
Use the correct size Torx bit and ensure it is firmly seated in the screw head. Avoid over-tightening.
Corrosion observed.
If the screws are exposed to harsh conditions, consider replacing them if significant corrosion is present. Ensure the surface is free from debris.
