Which screw bit is required for this screw?

You need a T-STAR plus T20 bit for an optimal grip and efficient torque transfer.

Is pre-drilling required before driving the screw?

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

What is the benefit of the partial thread?

The partial thread pulls the top wooden piece tightly against the base material without leaving a gap.

What does the WIROX coating provide?

The WIROX coating provides high corrosion protection suited for indoor applications and sheltered outdoor areas.

How does the countersunk multi-head work?

It countersinks flush into wood and stops cleanly on metal fittings to prevent surface damage.

Tight timber joins with Spax chipboard screws

Practical benefits

Maximum grip without slippage: The T-STAR plus T20 drive ensures precise bit guidance, allowing you to insert fasteners effortlessly without cam-out.
Powerful clamping with partial thread: The partial thread draws the top wooden layer tightly against the base material for a gap-free, secure connection.
Durable protection against corrosion: A specialised WIROX coating shields the hardened steel against rust, ensuring dependable fastening performance in interior projects.

In a nutshell

The right choise for

With the Spax chipboard screw, you achieve strong and seamless wood-to-wood joins across all your interior carpentry and furniture projects. The partial thread pulls wooden panels, battens, or frames tightly against the timber substructure without leaving gaps. Its countersunk multi-head sinks flush into the surface without tearing the material, while the 4CUT point reduces wood splitting and makes pre-drilling unnecessary in softwoods. The t-star plus T20 drive guarantees precise bit guidance to prevent cam-out and slipping during fastening. Finished with a protective Wirox coating, this box of 500 screws provides dependable performance for every fix.
