Why Metric Eye Bolts?
International Equipment Compatibility
Machinery manufactured for global markets is commonly designed with metric fasteners. DIN 580 metric eye bolts install directly without adapter plates, re-tapping, or modifications.
Regulatory & Documentation Support
ISO 3266 certification provides verified load ratings and material properties, supporting applications that require documented compliance, traceability, and inspection readiness.
Precision Thread Pitch
Metric designations such as M20 × 2.5 clearly define both diameter and pitch, eliminating confusion associated with mixed or unified thread systems.
Structural Consistency
DIN 580 specifications control shoulder height, eye diameter, and base width tolerances, ensuring consistent load transfer and reducing the risk of deformation or premature wear.
Angular Loading & Safety
Shoulder-type metric eye bolts are designed for angular loading up to 45° from vertical. At 45°, the allowable working load is reduced by approximately 75%. Always consult load charts and use spreader bars to maintain proper lifting geometry. Never exceed the maximum recommended angle.
Why Choose G-Fast?
G-Fast supplies DIN 580 and ISO 3266 certified metric eye bolts in carbon steel, A2 stainless steel, and B8 stainless steel. Comprehensive documentation, consistent quality, and technical support make G-Fast a reliable partner for global lifting and rigging requirements.
- Drop-forged construction for high tensile strength
- Integral shoulder design for angular loading up to 45°
- DIN 580 & ISO 3266 certified
