Strong wood joints with Spax

Practical benefits

Clean and flush finish: The countersunk head mills smoothly into the timber, giving you a flush surface without splitting or rough edges.
Tight fit with partial thread: You pull wooden components tightly together without gaps thanks to the high clamping force of the partial thread.
Long-lasting corrosion protection: The advanced WIROX coating protects your fasteners from rust, ensuring strong and durable indoor wood assemblies.

In a nutshell

The right choise for

With the Spax s chipboard screw 4,5 x 40 mm, you achieve strong and seamless wood-to-wood joints for furniture making, interior fitting, or fixing wooden battens.

The countersunk multi-head mills cleanly into the timber to provide a flush, splinter-free finish with no protruding screw heads. The PZ2 Pozidriv drive ensures reliable engagement and smooth driving. In addition, the chromium(VI)-free wirox coating delivers significantly higher corrosion resistance than conventional zinc plating, keeping your indoor timber assemblies strong and protected over time.
