BoxBolt® Blind Bolts for HSS Connections – No Welding or Drilling

BoxBolt blind bolts provide a certified solution for connecting to hollow structural steel (HSS) safely and quickly, without the need for through-bolting, welding, or tapping. Each bolt expands inside the steel section to create a secure, load-rated connection from one side only.

Available in zinc-plated, hot-dip galvanized, and stainless-steel finishes, BoxBolt delivers consistent performance and full ICC approval for total structural confidence. The BoxSok™ installation tool speeds up installation while maintaining reliable, code-approved strength.

Applications include: curtain walling, façade support, secondary steelwork, architectural metalwork, and any hollow section connection where access is limited.
