The Square Nut is a wide square-base nut component used in Alupan panel formwork systems to secure the end connections of tie-rod bars. Thanks to its large surface area, it distributes the load over a wider area and provides a secure grip under concrete pressure. Its steel body offers high strength and is manufactured for repeated use. In panel installations, it helps maintain stable tie-rod connections in shear wall and wall formwork, preventing the system from opening, shifting, or loosening. Installation is fast, application is practical, and it is fully compatible with other Alupan connection elements. The Square Nut is an ideal solution for safe and strong connections in panel formwork systems.
