Loading Angle Reduction Factors (DIN 580)

DIN 580 mandates WLL reduction when the lifting angle deviates from vertical (0°):

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 CR3 zinc plating and why is it preferred over CR6?
A: CR3 refers to trivalent chromium (Cr³⁺) passivation applied over electroplated zinc. It replaces the older CR6 (hexavalent chromium, Cr⁶⁺) process, which is classified as a carcinogen and restricted under RoHS and REACH regulations. CR3 provides comparable corrosion protection while being fully compliant with EU and international environmental directives.

Q: What is C15E steel and why is it used for DIN 580 eye bolts?
A: C15E is a low carbon case-hardening steel per DIN EN 10083 (material number 1.1141). It offers excellent forgeability, good toughness, and sufficient strength for DIN 580 lifting applications. Its low carbon content ensures good weldability and resistance to brittle fracture.

Q: Are these eye bolts suitable for outdoor use?
A: Zinc CR3 plated eye bolts are suitable for sheltered outdoor and indoor environments. For prolonged outdoor exposure, coastal, or marine environments, FULLERKREG recommends A4 stainless steel (SUS316) eye bolts for superior corrosion resistance.

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

Q: Are these eye bolts suitable for angular or side loading?
A: DIN 580 eye bolts are designed primarily for axial (vertical) loading. For angular loading, the WLL must be reduced per DIN 580 reduction factors (50% at 45°–90°). For frequent multi-directional loading, swivel hoist rings are recommended.

Q: Can I get RoHS compliance documentation?
A: Yes. FULLERKREG provides RoHS compliance certificates and material test reports upon request for wholesale and OEM orders.

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