Wirox 8000000286940 Universal Screw, 3.5 x 50 mm, Pack of 180, Fully Threaded, Phillips Z2, 4CUT

• Exclusive Wirox A9J coating: offers higher corrosion protection, higher surface hardness and is more environmentally friendly (chrome (VI) free) than conventional bare zinc plating. Can be used indoors and protected outdoors
• Phillips Z2 (Pozi): the further development of the cross force attack reduces the cam-out effect, because the four flanks of the screwdriver blade do not taper towards the tip
• Energy-saving work: thanks to the 4CUT tip, pre-drilling is usually unnecessary and the splitting effect is reduced. The wave-shaped thread of the SPAX allows quick and secure screwing and saves battery performance
• Flush countersinking of screws: with its polygonal bottom ("pockets"), the countersunk head mills itself into the wood or is braked when placed on metal to prevent over-tightening or damage to fittings

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.
