HECO 8.5 x 300 Cylindrical Head Double Thread Silver Zinc Steel T-40
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.
BENEFITS
Sinking into the wood made easy
Transfer of high tensile and compressive loads via the double thread
For universal use in new constructions and restorations
ADVANTAGES
HECO-TOPIX tip does away with the need for pre-drilling, reduces the risk of the wood splitting and enables narrow edge and centre distances.
