Which driver bit is required for these screws?

You need a T-STAR plus T20 bit. This bit fits snugly into the screw recess and prevents slipping.

What is the benefit of a partial thread?

The partial thread pulls the top wooden piece tightly against the underlying structure without leaving a gap.

What are the dimensions of the screw and thread?

The screw has a diameter of 4.5 mm, an overall length of 35 mm, and a thread length of 25 mm.

Is pre-drilling required before installation?

Pre-drilling is not necessary in softwoods or board materials due to the specialized tip. It is advised for hardwoods.

What does the WIROX coating offer?

The WIROX coating delivers significantly higher corrosion protection than standard zinc plating for indoor applications.

Dependable wood fastenings with Spax

Practical benefits

Superior bit engagement control: The T20 drive ensures your driver bit stays firmly seated, eliminating slippage while transferring driving torque cleanly.
Minimal risk of splitting: The sharp tip geometry easily displaces wood fibres, allowing you to drive screws close to edges without pre-drilling.
High corrosion resistance performance: A durable zinc coating safeguards the hardened steel core, ensuring your interior installations remain solid and secure.

In a nutshell

The right choise for

Build tight, gap-free indoor timber assemblies with the Spax 4.5 x 35 mm chipboard screw. Designed with a partial thread, it firmly clamps the top timber component against the substructure, making it ideal for batten framing, furniture construction, and sheet materials. The t-star plus T20 drive ensures clean bit engagement to prevent cam-out and slipping, giving you full driving control. Wood fibers are displaced smoothly by the sharp tip, minimizing the risk of splitting softwoods without requiring pre-drilling. The countersunk multi head finishes flush with the material surface, while the Wirox coating delivers superior corrosion resistance compared to standard zinc plating for dependable indoor fixings.
