You can assemble high-quality steeltimber joints using the HECO®-WS system. The dowels are inserted in the timber and through the steel plates in a single, time-saving operation without pilot drilling. 3 steel plates up to 5 mm thick or 1 steel plate with up to 10 mm thick can be penetrated (steel grade: S235). Producing joints for framework structures has been a complicated process to date. The new HECO®-WS system reduces the procedure to a few operating steps: 1. fitting the steel plate 2. aligning and fixing it in position 3. inserting the dowel FEATURES - Self-drilling dowel, cylindric countersunk head T-Drive Thread beneath the head Carbon steel Bright zinc plated THE ADVANTAGES AT A GLANCE PRODUCT ADVANTAGES Self drilling due to special drilling tip Numerous applications Simple, reliable calculation according to EN 1995-1-1 High yield moment My,k=31,93 Nm High fire resistance PROCESSING Easy to use with no pre-drilling of steel or timbers (max. 10mm; max.
