Lifting eye bolts are widely used fasteners in industrial, construction, and logistics fields. Their core function is to enable the lifting, transportation, or fixation of heavy objects through an eye structure. Typically manufactured from high-strength alloy steels such as 45# steel or 40Cr steel, these products undergo surface anti-corrosion treatments like galvanization or Dacromet coating to suit various environmental conditions. Their structural design features a rotatable eye and a bolt body. The eye is usually circular or D-shaped for easy connection with rigging equipment, chains, and other accessories, while the bolt part is tightly secured to fixed objects such as steel structures or equipment bases via its threaded portion.

| Aluminum | Excellent thermal/electrical conductivity but naturally soft. May produce gelatinous buildup during processing. |
| Titanium | EDM machining recommended. Requires deionized water to control heat during processing. |
| Steel | Very strong metal. Wire cutting machines often preferred for complex features. Requires heat management. |
| Brass | High tensile strength, easy to machine but requires slow cutting speed due to softness. |
- Reusable medium carbon steel construction
- Easy installation and disassembly
- Time-Saving: Eliminates the need for additional washers, streamlining assembly
- Improved Joint Integrity: Maintains consistent preload, reducing joint failure risks.
- Durable wholeness
