SPAX screw M for MDF boards countersunk head TORX

Countersunk wood screws with Torx grip for MDF panels. 
The Torx grip is SPAX’s unique T-STAR plus solution, providing a perfect fit and superior grip thanks to the extra pin solution! To take advantage of T-STAR plus, you will need SPAX T-STAR plus bits, but the screw can of course also be tightened with standard bits.
