How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Plain carbon steel nut without galvanizing | The hot-dipped galvanized version resists rust and corrosion in wet or marine environments, extending service life |
| Cast iron eye nut | Drop-forged steel has higher tensile strength and impact resistance, making it safer under dynamic loads |
| Threaded nut with lower safety factor | The 5:1 safety factor ensures greater margin of safety in lifting and rigging applications |
| Threaded nut with no stamping | Stamped working load limit enables quick field verification and compliance with safety standards |
Use Guide
How To Use And Inspect G-400 Threaded Eye Nut
- Verify the stamped working load limit matches the calculated load before use
- Ensure the nut is fully engaged on the eye bolt with no thread misalignment
- Inspect the galvanized coating for damage before installation; replace if compromised
- Do not exceed the stamped working load limit under any condition
- Check for thread wear or deformation after repeated use or exposure to vibration
- Retire the nut if the body shows deformation, the coating is severely damaged, or the marking is illegible
