Structural Steel Expansion Anchors
Request a QuoteBoxBolt is an independently tested and approved structural steel blind bolt which performs like an expansion anchor for steel. This allows for connections to steel sections where access is to one side only. The BoxBolt expansion anchor is suitable for use with rectangular, square or even circular hollow sections. The BoxBolt features a hexagon head design for installation with standard wrenches. When installation time is critical, the BoxSok installation tool is available.
The BoxBolt is available in three finishes: zinc plated, hot-dip galvanized and stainless steel. Three lengths of the BoxBolt are available to make it flexible for use with a wide grip range.
