Leading UK Manufacturer of BS 529 Imperial Collared Eyebolts.
We specialise in the precision manufacture and supply of high-integrity imperial collared eyebolts produced in strict accordance with BS 529 specifications, engineered for safety-critical lifting, rigging, and structural anchoring.
Utilising advanced closed-die drop forging and upset forging processes, we compress and align the material's grain flow along the contours of the component, delivering elite tensile strength, ductility, and fatigue resistance compared to machined or cast alternatives. Whether for heritage equipment maintenance, legacy machinery support, or bespoke engineering projects, we provide a complete, certified manufacturing solution.
