Lindapter M20 Type HB Hollo-Bolt Hexagonal Head
- Brand: Lindapter
Hollo-Bolt Hexagonal Head is an expansion bolt that only requires access from one side of the Structural Hollow Section (SHS)
Hollo-Bolt expansion bolts require access to only one side of the Structural Hollow Section (SHS), and 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.
Sizes M16 and M20 feature a High Clamping Force (HCF) mechanism to produce three times more clamping force than the same sized product without the mechanism.
