The wood construction screw for professionals. HECO-TOPIX-plus is a true highlight in screws, combining concentrated technological expertise with numerous tangible user benefits in one type of wood screw. The secret: For HECO-TOPIX-plus, we have merged the best features from four HECO product lines! With innovative features like HECO-Drive, GripFit, MagicClose, PerfectPitch, a new unified drive size concept, and high-quality system accessories, HECO-TOPIX-plus is the perfect wood screw for practically all applications. You benefit not only from the significant technological advantage but also from easy handling and optimal performance.
Product advantages:
GripFit: HECO-Drive allows for one-handed operation. It securely holds stainless steel screws on the bit (from screw diameter 3.5 mm).
PerfectPitch: Optimal thread pitch for every screw length. Perfect performance for all wood applications.
The HECO-TOPIX tip eliminates the need for pre-drilling, reduces the risk of wood splitting, and allows for tight edge and axis distances.
Countersunk head with milling pockets: Excellent milling properties in wood. No damage to the surface with metal fittings.
Shaft ribs reduce the screwing torque.
European Technical Assessment: ETA-19/0553.
Note: Some alternative wood construction variants with drive size TX-25 (without GripFit effect) are available.
