MaxxFast Universal Woodscrew with a countersunk head and ttap® technology, manufactured from zinc-plated steel for basic corrosion protection and reliable performance in indoor timber applications. This versatile screw is suitable for a wide range of timber uses, providing dependable grip and strong withdrawal resistance in both softwood and hardwood. The countersunk head ensures a flush, neat finish where a smooth surface is required. The ttap® feature enhances driving performance, reducing cam-out and allowing consistent seating without excessive torque. The zinc-plated steel construction offers adequate protection for interior joinery and general carpentry tasks while maintaining good strength for everyday fastening. Please note that certain small-diameter variants (3 and 3.5 mm) are not suitable for structural timber joints and are not CE marked; the specified 9 mm drive minimum applies only when selecting longer lengths (F = 9 mm if L ≥ 40 mm).
