Which driver bit do you need for these screws?

You need a T20 bit. The T-STAR plus drive provides a secure fit and prevents bit slippage during driving.

What is the benefit of the partial thread?

The partial thread pulls the upper timber piece tightly against the base material, creating a gap-free joint.

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

Pre-drilling is generally not required in softwoods thanks to the 4CUT point. Pre-drilling is recommended for hardwoods.

What is the thread length of this 80 mm screw?

On this 80 mm screw, the thread length is 46 mm. The unthreaded shank section measures 34 mm.

What are the benefits of the WIROX coating?
