SPAX T-STAR plus drive increases the contact surface of our T-STAR plus and ensures optimal positioning for the T-STAR plus bits in the screw head. By enabling maximum force transmission from the screwdriver to the screw, T-STAR plus guarantees simple and ultra-fast work. For firmer and faster driving with less effort, choose these SPAX T-STAR Plus wood screws. The head is designed to offer maximum, precise force transmission from the screwdriver to the screw - insertion is simple, fast and efficient, with no annoying bit slips. Screws can be countersunk into the wood cleanly and flush, with almost no need to pre-drill thanks to the sharp 4CUT point - even in the edge areas of your workpiece that are normally prone to splitting. With a WIROX coating too, the screws benefit from extra protection and durability. T-STAR Plus drive - optimum bit position in screw head. Firmer and faster driving - no more bit slips. Countersunk head for a flush fit in the wood. No pre-drilling required (wood-dependent). 4CUT point reduces wood splitting and tearing. WIROX coating for excellent corrosion protection.
