Product description

The HECO-TOPIX-plus CombiConnect is an ETA-certified double-threaded screw, specially developed for the transmission of high compressive and tensile loads in wood construction applications. It features two threads with different thread-pitches, and enables a contraction of the construction components. The transmission of loads is done axially via the thread. This allows significantly higher tensile loads compared to conventional part-threaded screws. The HECO-TOPIX-plus CombiConnect can be processed quickly and without splitting, and ensures an easy and user friendly handling.
