The HECO-UNIX-top Floorboard screw pulls timber components together as it is driven in, leaving no gaps, whilst simultaneously fixing the components via the thread. That allows not only a quick and cost-saving working, but also reliably prevents annoying creaking of the floorboards at the screw shank. As the loads are transferred via the thread, the head is used solely for driving and can be designed very small. It can be used in narrow tongue-and-groove mounting areas and does not overlap in subsequent components. That ensures a precise connection of profiled timber components. In addition the patented "TOPIX" drilling tip reduces the splitting of timber, enabling the usage in thinnest profiles with lowest edge distances.

Product strengths

  • Fast, economic and efficient assemblance: mounting and fixing of boards with just one type of screw
  • No creaking of floorboards due to fixation with HECO-UNIX full thread
  • Easy countersinking of the head into the tongue with reduced spreading effect
  • Time saving due to the use of only one type of screw
  • CE-marking
  • Reduced splitting effect during insertion due to the HECO-TOPIX┬« tip with milling ribs
  • Gapless joining of floorboards due to fixation with HECO-UNIX full thread
