SPAX Universal Screw, M4 x 0.7, 4.0 mm, 90 pcs, Fully Threaded, Countersunk Head, Phillips Z2, 4CUT, Wirox A9J Coating

• Long-term protection: with the high-quality Wirox A9J coating, the screws remain permanently corrosion-proof and resistant – ideal for stable wood connections indoors and protected outdoor areas
• Time-saving: the 4cut tip and the corrugated thread allow easy screwing in without pre-drilling, reduce the splitting effect and accelerate assembly with lower energy requirements
• Secure drive: the Phillips Z2 reduces the cam-out effect thanks to optimised flank shape - ensures a firm hold of the bit and clean work without damaged screw heads
• Durable connections: the full thread distributes forces evenly from tip to head - the multi-countersunk head ensures flush countersinking in the wood and prevents damage to fittings
• German brand quality: the SPAX screws from German production stand for precise workmanship, reliable performance and long-lasting connections indoors and protected outdoor areas

SPAX provides a comprehensive range for a wide range of applications. Professional users and experienced DIY enthusiasts trust the quality and know-how of SPAX for their DIY projects. The exclusive Wirox A9J coating from SPAX offers higher corrosion protection than conventional bare zinc plating and is more resistant to mechanical stress thanks to its significantly higher surface hardness. This makes it ideal for indoor and outdoor use in buildings where it is not exposed to direct weathering. The full thread extends the entire or almost entire length from tip to head. The more threads a screw has, the greater the tensile and compressive forces that can be absorbed by these screws. Useful especially in structural timber construction, where fully threaded screws are used for heavy-duty wood connections without additional fittings. Our countersunk screws are pronounced with a 90° multi-head. With its polygon underside ("pockets"), the countersunk head milles its appropriate recess in the wood itself and then closes flush with the surface - without pre-drilling or countersinking the screw hole. When placed on metal, the screw is braked and prevents over-tightening. The Phillips Z2 (Pozi) is a further development of the cross force attack and reduces the cam-out effect because the four flanks of the screwdriver blade do not taper towards the tip.
