Eye to Jaw - Turnbuckle System

Leading UK Supplier of Eye-to-Jaw Turnbuckles.

We specialise in the supply of high-integrity Eye-to-Jaw Turnbuckles (Rigging Screws), engineered as a versatile tensioning and articulation component for architectural steelwork, rigging assemblies, and structural bracing.

Designed with a closed eye on one extremity and a clevis/jaw with a removable pin on the other, our turnbuckles allow for secure hybrid attachment while providing precise length and tension adjustment within structural tie rod systems.

Utilising advanced in-house hot forging, thread rolling, machining, and assembly cells, for production of bespoke solutions, we ensure consistent structural performance, optimal material grain flow, and precise thread tolerances across every production run.
