Carbon steel eye bolt

Carbon steel eye bolt is a fastening and lifting component designed with a circular eye at one end and threaded shank at the other, widely used for lifting, rigging, anchoring, and load securing applications. It enables connection with hooks, shackles, ropes, or chains, providing a reliable attachment point for vertical lifting or directional load handling when properly installed. Carbon steel eye bolts are commonly used in machinery installation, structural engineering, and industrial equipment where controlled load transfer and secure anchoring are required.

ZSD Screw specialize in high-strength carbon steel eye bolts designed for structural lifting and industrial fastening applications. By integrating in-house forging, machining, precision thread rolling, heat treatment, and non-destructive inspection processes with strict quality control systems, ZSD Screw delivers reliable, international-standard lifting fasteners directly to global customers. Each production batch undergoes mechanical performance verification to ensure dimensional accuracy, tensile strength consistency, and dependable load-bearing capacity under regulated working conditions.

Standard eye bolt dimensions are manufactured according to DIN, ISO and ASTM standards. Custom drawings and samples are accepted.
