Which screw bit is required for these screws?

You use a T20 bit (T-STAR plus) for these screws.

What is the benefit of a full thread?

A full thread provides high pull-out resistance and a solid hold along the entire 50 mm length.

What is the function of the countersunk multi head?

It mills cleanly flush into wood and stops on metal without damaging the fitting.

What are the advantages of the WIROX coating?

The WIROX coating offers significantly higher corrosion protection compared to standard zinc plating.

Spax chipboard screws for secure timber joints

Practical benefits

Maximum torque without slipping: The T20 drive ensures a tight bit fit so you can drive screws smoothly without cam-out or wasted effort.

Reliable protection against corrosion: Featuring a durable Wirox coating, this steel screw protects your builds from rust during indoor and sheltered outdoor woodworking tasks.

In a nutshell

The right choise for

With Spax chipboard screws, you create strong and dependable timber joints with ease. The t-star plus T20 drive provides optimal torque transfer, keeping your bit firmly engaged and preventing cam-out during demanding driving tasks. Thanks to full threading across the entire 50 mm length, you achieve maximum pull-out resistance when joining wood panels or mounting metal hardware. The countersunk multi-head sinks neatly flush into the wood surface, eliminating the need for separate pre-countersinking. Additionally, the durable Wirox coating delivers superior corrosion protection to the steel, keeping your interior and sheltered outdoor constructions solid over time.
