Which screwdriver bit is required for this screw?

You need a T-STAR plus T20 or a standard Torx T20 bit for optimal engagement.

Is this screw suitable for outdoor applications?

Yes, the A2 stainless steel (INOX) construction provides reliable corrosion resistance for outdoor use.

What is the advantage of a full thread?

Full threading provides high pull-out resistance and absorbs tension and compression forces along the entire screw.

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

Pre-drilling is generally not required in softwoods, but it is always recommended for hardwoods.

What does the countersunk multi head do?

The ribs on the underside cut cleanly into the wood, allowing the screw head to countersink flush.
