Hollo Bolt

The Hollo-Bolt eliminates the need for conventional through-bolting or welding of structural hollow section or ant steel structures where access is only available from one side.

Suitable for hollow sections, tubes and where access is available from one side only. The Hollo-Bolt is continuously developed to meet the requirements of Structural Engineers, with recent performance improvements including the patented High Clamping Force (HCF) version. The Hollo-Bolt is protected by multiple international patents and registered designs.
