Which bit size do you need for this screw?

You need a T20 bit, preferably a T-STAR plus bit for optimal fit and grip without cam-out.

What is the benefit of a partial thread?

A partial thread pulls the upper timber piece tightly against the underlying material without gaps.

What does the WIROX coating offer?

WIROX is a chromium-VI-free coating that provides significantly higher corrosion resistance than standard zinc plating.

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

Pre-drilling is generally not required in most softwoods. It remains recommended when working with hardwoods.

What is the thread length of this 80 mm screw?

The threaded section measures 37 mm.
