Which screwdriver bit is required for these Spax screws?

You need a T20 (T-STAR plus) bit for a precise fit and optimal torque transfer without cam-out.

What are the advantages of the Wirox coating?

The Wirox surface finish offers significantly higher corrosion resistance than standard zinc plating.

Do you need to pre-drill before driving these screws?

Pre-drilling is generally not required in soft timber thanks to the 4CUT point, but is recommended in hardwood.

What is the purpose of the multi head?

It countersinks cleanly and flush into wood while stopping on metal hardware to prevent stripping.

What is the benefit of a full thread screw?

The full thread provides maximum resistance against tensile and compressive forces across the joint.
