HECO ITALIA EFG SFS WT-T - Стальной винт

SFS WT-T is a double-threaded screw with European ETA certification developed for joints and reinforcements in timber construction.‎ The two threads have a different geometry in order to create a coupling effect.‎ Stresses are transferred axially through the thread which, compared to conventional partially threaded screws, provides significantly higher tensile strengths.‎ SFS WT-T can also be used for compression loads.‎ Thanks to the SMARTBITE bit, the screw is easily inserted without pre-drilling, ensuring fast, simple and effective processing.‎ The two threads with different geometries ensure the coupling between the two woods; The certified high strength values create a secure and long-lasting fastening, as well as fast and effective installation; SMARTBITE drill bit: for a perfect mix of perforating capacity, with no risk of cracking, and speed of engagement; Small cylindrical head, perfect for crack-free insertion into wood.‎ It is also less visible; Free technical consulting service and SFS Designer calculation software; ETA certified and guaranteed product; Suitable for both wood-to-wood joints and reinforcement of beams or wood panels.‎
