Leading UK Manufacturer of Hexagon Open Body Turnbuckles.
We specialise in the precision manufacture and supply of high-integrity Hexagon Open Body Turnbuckles (Rigging Screws) similar to BS 4429, engineered as a reliable and visible tensioning component for structural steelwork, rigging assemblies, and architectural tie rod networks.
Designed with an open-frame hexagonal barrel, these turnbuckles offer clear visual inspection of thread engagement alongside smooth length adjustment.
Utilising advanced in-house hot forging, machining, thread rolling, and assembly cells, we ensure consistent structural performance, optimal material integrity, and precise thread tolerances across every production run.
