Which screw bit is required for this Spax screw?

You need a T20 bit (T-STAR plus T20 or standard Torx T20).

What is the benefit of a partial thread?

The partial thread pulls the upper board tightly against the lower structure, ensuring a gap-free joint.

What is the thread length of this screw?

The overall screw length is 30 mm, with a thread length of 17 mm.

What protection does the Wirox coating provide?

The Wirox coating offers significantly higher corrosion protection than standard zinc plating for indoor and sheltered outdoor use.

How does the countersunk multi-head work?

The head mills cleanly into the wood for a flush finish without requiring separate countersinking.

Strong wood joints with Spax

Practical benefits

Superior bit grip security: The T-STAR plus T20 drive eliminates cam-out and ensures optimal torque transfer while you drive screws.
Clean flush surface finish: The multi countersunk head sinks cleanly into the timber without splitting the workpiece surface.
High resistance against corrosion: The durable WIROX coating delivers enhanced protection against rust for all your indoor construction projects.

In a nutshell

The right choise for

Create solid wood joints without gap formation using this Spax chipboard screw. Thanks to the partial thread, you pull timber boards or battens tightly against your substructure, making it ideal for indoor furniture assembly and interior fittings. The t-star plus T20 drive eliminates bit slippage and guarantees direct torque transfer. With its countersunk multi-head, the screw sinks cleanly and flush into the timber surface without splitting the wood or requiring pre-drilling. In addition, the Wirox coating provides significantly higher corrosion protection than standard galvanized steel for dry indoor and sheltered applications. Supplied in a box of 1000 pieces in 4.5 x 30 mm, you have everything needed to work efficiently.
