Which screw bit is required for these screws?

You need a T20 bit (T-STAR plus or standard Torx) for a secure fit and optimal torque transfer.

What is the advantage of the partial thread?

The partial thread pulls the top component tightly against the underlying structure without leaving gaps.

Do you need to pre-drill before driving these screws?

In most softwoods, pre-drilling is not required thanks to the specialized screw point.

What level of protection does the WIROX coating provide?

The WIROX coating delivers significantly higher corrosion protection than standard zinc plating in indoor and covered outdoor areas.

How does the screw head sit in the wood?

The countersunk multi-head countersinks cleanly and sits flush with the timber surface.

Solid timber fastening with Spax

Practical benefits

Secure grip without slipping: The T-STAR plus T20 drive eliminates bit cam-out, letting you sink screws quickly and securely.
Clean flush surface finish: The multi-head countersinks itself neatly into the timber without tearing wood fibers.
Tight clamping performance: The partial thread draws the outer wood component tightly against the base for rigid joints.

In a nutshell

The right choise for

With Spax 4 x 70 mm chipboard screws, you assemble timber frames, floor panels, and bespoke furniture with ease and precision. The t-star plus T20 drive ensures a secure bit fit and eliminates slipping or cam-out during high-torque driving. Featuring a 37 mm partial thread, each screw pulls the top wooden component tightly against the base structure for a gap-free, solid joint. The countersunk multi-head sinks smoothly flush into the timber surface without tearing fibers or damaging the wood. In addition, the galvanized wirox coating delivers enhanced corrosion resistance for interior joinery and protected outdoor applications.
