Which screwdriver bit is required for this timber construction screw?

You need a T-STAR plus T40 or standard Torx T40 bit.

What is the benefit of the washer / disc head?

The wide disc head provides high head pull-through resistance and clamps timber components securely.

Do you need to pre-drill before driving the screw?

Pre-drilling is generally not required in softwoods, though it is recommended in hardwoods.

What level of protection does the WIROX coating provide?

The WIROX surface coating delivers significantly higher corrosion protection than standard zinc plating.

When should you use a full-thread timber screw?

Full-thread screws are designed to absorb high tensile and compressive forces in structural timber connections.
