As part of the company’s 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.

The business is now pleased to announce that its 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.

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.
