Dimensional Specifications — DIN 580 Lifting Eye Bolts

All dimensions in millimeters (mm). Working load limits (WLL) are for axial (vertical) loading only. For angular loading, apply the appropriate reduction factor per DIN 580.

Loading Angle Reduction Factors (DIN 580)

DIN 580 specifies that the working load limit must be reduced when the lifting angle deviates from vertical (0°). The following factors apply:

Sling Angle (from vertical)	WLL Reduction Factor	Example: M20 WLL
0° (axial / vertical)	1.00 (100%)	1,800 kg
Up to 45°	0.50 (50%)	900 kg
45° – 90°	0.50 (50%)	900 kg

⚠️ For angular loading exceeding 45°, always consult a qualified rigging engineer. Never exceed the rated WLL.

Frequently Asked Questions

Q: What is the difference between DIN 580 and DIN 582?
A: DIN 580 covers lifting eye bolts (with a threaded shank for screwing into a tapped hole), while DIN 582 covers lifting eye nuts (with an internal thread for use on a bolt or stud). Both are used in rigging but serve different attachment configurations.

Q: Are these eye bolts suitable for side loading?
A: DIN 580 eye bolts are designed primarily for axial (vertical) loading. For angular or side loading, the WLL must be reduced per the DIN 580 reduction factors. For frequent multi-directional loading, consider swivel hoist rings instead.

Q: What surface treatment is applied?
A: FULLERKREG DIN 580 A2 eye bolts are whitened (acid-washed) and passivated, which removes surface contamination and enhances the natural chromium oxide passive layer for maximum corrosion resistance.

Q: Can I get material test reports (MTR)?
A: Yes. FULLERKREG provides material test reports and inspection certificates upon request for wholesale and OEM orders.

Q: What is the thread standard?
A: All threads are metric coarse (ISO/DIN 13), compatible with standard metric tapped holes.
