Clean and split-free fastening by Spax

Practical benefits

Screw directly without predrilling: The specialized cut point bores through fibreboards cleanly so you prevent material bulging and splitting near edges.
Flush and smooth finish: The compact milling head sinks neatly into the surface, giving you a completely flush aesthetic in furniture assembly.
Superior bit engagement: The T-STAR plus T15 drive eliminates cam-out and ensures maximum torque transfer while you drive each screw.

In a nutshell

The right choise for

With the Spax Spax-M wood screw, you assemble mdf, hdf, and chipboard without splitting or bulging the material. The specialized cut point lets you drive screws directly without pre-drilling, even near edges. Its partial thread pulls panels tightly together for rigid, gap-free joints in furniture assembly and interior fitting. The compact countersunk milling head sinks neatly into the board, leaving a completely flush surface. Thanks to the t-star plus T15 drive, you get a secure bit fit with maximum torque transfer and zero cam-out. Finished with a Wirox coating, this screw provides reliable corrosion protection for interior woodworking.
