• WIROX A9J coating offering high corrosion protection and greater resistance than conventional galvanizing. • Special 4CUT point that allows screwing without the need for pre-drilling, reducing effort and extending battery life. • T-STAR plus T20 drive with guide pin for a secure bit fit and optimal force transmission. • MULTI countersunk head with polygonal base that mills into the wood to sit perfectly flush with the surface. • Full thread providing maximum stability by directing tensile and pressure forces along the entire screw. • Made in Germany following high quality standards for wood connections in protected indoor and outdoor areas.
