Hollo-Bolt expansion bolts require access to only one side of the Structural Hollow Section (SHS), and offer a faster alternative to welding or through-bolting, enabling contractors to reduce construction time and labour costs. Installation is quickly carried out by inserting into pre-drilled steelwork and tightening with a torque wrench. Also suitable for blind connections where access is available from one side only.
The larger M16 and M20 Hollo-Bolts are optimised for high strength structural connections and feature a unique High Clamping Force (HCF) mechanism for superior performance.
