Type HB Hollo Bolt
The Lindapter Type HB Hollo- Bolt is the original expansion Bolt for structural steel and is used for hollow section tube or conventional steel where access is restricted to one side. The Hollo-Bolt is a cost-effective, secure solution that allows for rapid installation with standard tools without the need to weld, drill or tap steelwork, reducing construction and labour costs.
For corrosion protection the Hollo-Bolt® comes as bright zinc plated plus JS500 protection as standard, or hot dip galvanised. Hollo-Bolts are also available in grade 316 stainless steel.
Sizes M16 and M20 have a patented High Clamping Force (HCF) mechanism for optimised clamping force. Awarded the Design Council’s Millennium Product status for innovation in the year 2000.
