BoxBolt is designed with a sleeve that expands on the inside of the connection creating a strong geometrical interlock. It works everywhere, can be used with rectangular, square and even circular hollow sections and features a hexagon head design to aid installation with a standard spanner. When installation time needs to be kept at an absolute minimum, BoxBolt can be installed using the BoxSok installation tool. BoxBolt is available in three finishes: Zinc Plated, Hot Dip Galvanised and Stainless Steel. These finishes combined with three available lengths and multiple head styles make BoxBolt the most flexible solution suiting almost any environment and application. BoxBolt is ETA assessed, is approved for use by Lloyds Register (LR) and ICC-ES rated. Thanks to all these approvals BoxBolt complies with the latest steel constructions codes worldwide providing the designer and the user with total confidence and peace of mind. BoxBolt is also listed as a solution for connecting Hollow Steel Sections as referenced in the AISC manual.
