Lindapter Fire Rated Hollo-Bolts

Lindapter Hollo-Bolts are now independently Fire Rated for up to 120 minutes. As part of our continued commitment and investment in product development and testing Lindapter 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 (SHS). They 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. We are now pleased to announce that our carbon steel, hexagonal head Hollo-Bolts in all sizes have been fire tested in accordance with ISO 834 and are now fire rated up to 120 minutes. This provides further reassurance to construction professionals working with Lindapter and demonstrates our commitment to quality and transparency of product performance by increasing the volume of independent data that we have.
