Countersunk Hollo-Bolt®

Economize construction time and labor costs with Hollo-Bolt expansion bolts, specifically designed for Structural Hollow Sections (SHS). Simply insert into pre-drilled steelwork and tighten with a torque wrench to create a sturdy and efficient connection. The 'Countersunk Head' version minimizes protrusion from the steelwork and is ideal for blind connections where access is limited to one side. The larger M16 Hollo-Bolts are expertly engineered for heavy-duty structural connections, utilizing a High Clamping Force (HCF) mechanism for maximum strength.
