25/06/2013 16:01:55 Lindapter has launched its High Clamping Force (HCF) Hollo-Bolt, an enhanced version of its original expansion bolt for Hollow Structural Sections (HSS), which is optimised for structural connections.

The Hollo-Bolt is a faster alternative to conventional HSS connection methods such as welding or through-bolting, enabling contractors to reduce construction time and labor costs.

The Hollo-Bolt HCF is available as standard in sizes M16 (5/8”) & M20 (3/4”) and features Lindapter’s patented HCF mechanism that produces a typical clamping force three times higher than the same sized product without the mechanism. The increased clamping force results in a more secure connection.

Working closely with structural engineers and steel fabricators, Lindapter identified the need for the larger M16 (5/8”) & M20 (3/4”) products to provide an increased clamping force that would be suitable for structural connections. Research and development led to the invention of the patented 5-part design, with an innovative washer that compresses during installation to significantly increase clamping force between the fixture and the hollow section. The superior performance minimizes displacement (movement in the connection) at Safe Working Load for a more secure connection. The Hollo-Bolt HCF is designed to save steel contractors time and money and is exclusive to Lindapter.

The Hollo-Bolt is recognized by the AISC as a HSS connection method and by the BCSA/SCI as a primary structural connection ideal for other safety critical applications such as securing steel canopies, roofs and cladding. Furthermore, the Hollo-Bolt has recently gained the full seismic approval from ICC-ES, click here for more information.
