FAQs

What is the primary application for these screws?

These screws are primarily used to join timber to steel frame buildings.

What type of driver is required?

A TORX(r) compatible driver bit is required.

What is the advantage of the breakaway wings?

The breakaway wings create a clearance hole in the timber to protect the screw thread from damage and ensure proper engagement with the steel.

Are these screws corrosion-resistant?

Yes, they are salt spray tested to 1000 hours for enhanced corrosion resistance.

What is the clamping thickness for the 5.5 x 50mm screw?

The clamping thickness is 21mm.

What is the effective thread length of the 5.5 x 50mm screw?

The effective thread length is 22mm.

What is the drill tip type?

No.5 drill tip for self-drilling heavy gauge steel up to 12.5mm.

Are these screws suitable for outdoor use?

Yes, the corrosion resistance makes them suitable for many outdoor applications.

Troubleshooting

Screw is difficult to drive in.

Ensure you are using the correct TORX(r) driver bit. Apply steady pressure while driving the screw. If the steel is particularly thick, consider pre-drilling a pilot hole.

Screw head is not flush.

Ensure the countersunk head is properly seated. If necessary, adjust the driving depth to achieve a flush finish.

Screw is not holding securely.

Verify that the correct screw size and length are used for the application. Make sure the screw has fully engaged with the steel frame.
