Leading UK Manufacturer of Hexagon Closed Body Turnbuckles (DIN 1479)
We specialise in the precision manufacture and supply of high-integrity Hexagon Closed Body Turnbuckles (Rigging Screws) manufactured to DIN 1479, engineered as a robust and streamlined tensioning component for architectural steelwork, tie rod assemblies, and structural bracing.
Designed with a protective closed hexagonal body profile, these turnbuckles provide high torsional rigidity, structural neatness, and secure length adjustment.
Utilising advanced in-house machining, thread tapping, and bar-turning cells, we ensure consistent structural performance, smooth adjustment, and precise thread tolerances across every production run.
