The longitudinal connection of sleepers or purlins and of narrow components is - in terms of carpentry, executed as overleafing - enormously complex and time-consuming. It is much easier and faster with our SPAX flat connectors. The combi-perforation makes it possible to make not only wood/wood but also wood/concrete connections with 6 or 10 mm dowels or concrete screws. We provide two versions, whereby our SPAX flat connector heavy SXFLH has more to offer, especially in the usable width. For nailing out, our SPAX wood connector screws and SPAX grooved nails are the first choice.This means for you: Quick and easy connection of wood to wood and wood to concrete possible.
