Type HB Hollo-Bolt™ Hexagonal Head
Hollo-Bolt Hexagonal Head is an ICC-ES approved expansion bolt that only requires installation access from one side of the Hollow Structural Section (HSS).
Overview
Hollo-Bolt (Hot Dip Galvanized) expansion bolts are ICC-ES and LARR approved for use in all Seismic Design Categories A through F, in compliance with the International and Los Angeles Building Codes. They require installation access to only one side of the Hollow Structural Section (HSS), and offer a faster alternative to welding or through-bolting, enabling contractors to reduce construction time and labor costs. Installation is quickly carried out by inserting into pre-drilled steel and tightening with a torque wrench. Also suitable for blind connections where access is available from one side only.
The larger 5⁄8" and 3⁄4" Hollo-Bolts are optimized for high strength structural connections and feature a unique High Clamping Force (HCF) mechanism for superior performance.
NEW Carbon steel, hexagonal head Hollo-Bolts have been independently fire tested under tensile and shear loading with simultaneous exposure to standard fire conditions in accordance with ISO 834/ASTM E-119 for 120 minutes. For further details and load data please contact Lindapter.

• Hollo-Bolts can be used on a wide variety of steel hollow shape sections. Safe working loads shown are based on use in S275 structural hollow section and are applicable to the Hollo-Bolt only in both tension and shear. Failure of the section, particularly on those with thin walls and a wide chord face, could occur at a lower figure and its strength should be checked by a qualified Structural Engineer.
* Carbon steel, hexagonal head Hollo-Bolts in all sizes. For further details and load data please contact Lindapter.
