Leading UK Manufacturer of Tunnel Bolts & Curved Bolts.
We specialise in the precision manufacture and supply of high-integrity Tunnel Bolts and Curved Bolts, engineered as specialised structural fasteners for civil engineering, underground tunnelling, and curved segment fastening applications.
Designed with a custom radius or bend to match curved concrete or metallic infrastructure linings, our tunnel bolts deliver robust clamping force and secure alignment under high-load environments.
Utilising advanced in-house hot and cold bending, precision forging, and thread-rolling cells, we ensure consistent mechanical performance, accurate radius profiling, and strict adherence to dimensional standards across every production run.
