Carbon Steel Grade 4.8 8.8 10.9 12.9 Black Oxide Full Thread Eye Bolt DIN444

This DIN444-compliant eye bolt is built for industrial lifting, securing, and hoisting, with a range of carbon steel strength grades to match diverse load needs. Grades 4.8 handles light loads, 8.8 suits medium-heavy tasks, 10.9 works for heavy-duty use, and 12.9 tackles extra-heavy lifting—all with clear tensile and yield strength guarantees. Its full-thread design ensures a secure connection to lifting brackets, while the black oxide finish boosts wear resistance and adds mild corrosion protection for dry or indoor environments. The smooth inner eye edge protects lifting slings from fraying, making it reliable for machinery hoisting, equipment securing, and industrial component lifting across different load scenarios.

1. Light-load indoor industrial lifting (Grade 4.8)
2. Medium-heavy machinery hoisting and securing (Grade 8.8)
3. Heavy-duty industrial equipment fixing (Grade 10.9)
4. Extra-heavy component lifting in industrial settings (Grade 12.9)
5. General indoor lifting and anchoring tasks (all grades, dry environments)

1. Q: What’s the purpose of offering multiple carbon steel grades (4.8/8.8/10.9/12.9) for this eye bolt?

   A: Different grades match different load needs—4.8 for light loads, 8.8 for medium-heavy, 10.9 for heavy, and 12.9 for extra-heavy. This lets users pick the exact strength required for their lifting task, avoiding over-specifying or safety risks.

2. Q: How does the "black oxide finish" protect the eye bolt?

   A: Black oxide boosts wear resistance to prevent surface scratches during installation and use. It also provides mild corrosion protection, making the bolt suitable for dry or indoor industrial environments.

3. Q: Why is the "full thread" design important for lifting applications?

   A: Full thread means the thread runs continuously from the eye base to the shaft end. This ensures a secure, even connection to lifting brackets or nuts—no weak points from partial threading, which enhances lifting safety.

4. Q: What does DIN444 compliance mean for this eye bolt’s performance?

   A: DIN444 sets strict standards for eye geometry, thread precision, and load ratings. Compliance guarantees the bolt’s dimensions and strength are reliable, so users can trust its rated load capacity for safe lifting.

5. Q: Can this eye bolt be used outdoors or in humid environments?

   A: It’s best for dry, indoor settings. The black oxide finish only offers mild corrosion protection—outdoor or humid environments may cause rust over time, so a more corrosion-resistant coating (like zinc plating) would be better there.
