As part of Lindapter’s continued commitment and investment in product development and testing, the company has commissioned the Building Research Establishment (BRE) to independently fire test Lindapter Hollo-Bolts.
Lindapter’s Hollo-Bolt Hexagonal Head is an expansion bolt that only requires access from one side of the structural hollow section. These bolts 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. Lindapter states the bolts are also suitable for blind connections where access is only availbile from one side.
The 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, providing quality reassurance to construction professionals.
