Zinc Steel Eye Bolt

The zinc steel eyelet screw is a fastener designed for hanging, fixing, and traction. It is made of high-quality carbon steel and treated with black zinc on the surface. It has high load-bearing capacity and corrosion resistance. Its unique eyelet (ring head) design facilitates the connection of ropes, chains, or hooks, and is widely used in construction, stage equipment, warehousing and logistics, and other fields.

1. High-strength carbon steel material, reliable load-bearing
Q235 carbon steel (tensile strength ≥ 400 MPa) is used, cold-headed and tempered to ensure that the screw does not deform under heavy loads. Compared with ordinary iron screws, carbon steel has higher strength and toughness, and is suitable for load-bearing scenes such as hoisting and suspension. After heat treatment, the fatigue life of the screw is increased by 30%, making it suitable for long-term, repeated use.

2. Black zinc surface treatment, rust-proof and wear-resistant
The average thickness of the galvanized layer is 8-12μm, and the salt spray test is ≥48 hours without red rust. A dense oxide film is formed on the surface of the zinc layer to enhance corrosion resistance while providing a matte black appearance. More resistant to environmental corrosion (such as rain and humid air) than ordinary galvanizing. The black appearance is more beautiful and low-key, suitable for a variety of indoor and outdoor scenes.

3. Sheep eye design for easy hanging and fixing
The inner diameter of the ring head is standard (such as the inner diameter of the M8 sheep eye ring ≈ 10mm), suitable for common ropes and hooks. The ring body is smooth and burr-free to avoid abrasion of ropes or cables. Compared with ordinary eye screws, the ring structure of the sheep eye is easier to thread the rope, and the force is evenly distributed and not easy to deform.

Typical application scenarios of carbon steel black zinc sheep eye screws
Construction and decoration: ceiling keel fixing, cable tray suspension.
Stage and exhibition: hoisting of lighting and audio equipment, excellent anti-vibration performance.
Warehousing and logistics: shelf reinforcement, hoisting connection, suitable for high-frequency use.
Outdoor facilities: awnings, fixed billboards, black zinc layer to resist sun and rain.
