FAQs

What is the purpose of the WIROX coating?

The WIROX coating provides excellent corrosion protection, extending the lifespan of the screws, especially in outdoor applications.

What is the T-STAR Plus drive?

The T-STAR Plus drive is a special recess in the screw head that allows for a more secure fit and better driving performance, preventing bit slips.

Do I need to pre-drill when using these screws?

Pre-drilling is not always necessary and depends on the type of wood. For softer woods, it may not be needed, but it is recommended for hardwoods to prevent splitting.

What size screws should I use?

The screw size depends on the thickness of the wood you are using. Refer to the SPAX recommendations or consult a building professional for guidance.

Can I use a regular screwdriver with these screws?

No, you must use a T-STAR Plus bit for installation.

Where can I use these screws?

These screws are best suited for use in timber construction projects like battens, facades, stairs, and other similar applications.

What does the 4CUT point do?

The 4CUT point cuts through wood fibers, reducing splitting and lowering the screwing-in torque required.

Troubleshooting

Screw head stripping during installation.

Ensure the correct T-STAR Plus bit is used and that it's properly seated in the screw head. Reduce driving speed if necessary.

Wood splitting when driving screws.

Pre-drill pilot holes, especially in hardwoods. Ensure the correct screw size for the wood thickness is being used.

Screw not going in straight.

Ensure the drill is perpendicular to the wood surface when starting the screw. Apply consistent pressure.

Setup, Compatibility & Care

Setup
