Hex Socket Eccentric Screws - Grade 12.9 Steel - ±1.5-3.0mm Offset - Machinery Alignment - Dacromet Coated

Correct structural misalignments with hex drive eccentric screws. ±1.5-3.0mm offset. Grade 12.9 alloy steel, Dacromet coated. For mining/conveyor equipment. Hex sizes: H8-H14. Custom offsets.

Engineered for **heavy industrial frame realignment**, these **Hex Socket Eccentric Screws** feature a **precision-machined off-axis shank (±1.5-3.0mm offset)** to compensate for drilling errors up to 6mm. Constructed from **quenched-tempered 42CrMo alloy steel (Grade 12.9)**, they deliver 1,200MPa tensile strength with **Dacromet coating** resisting corrosion in abrasive environments. The **internal hex drive (H8-H14)** enables high-torque installation without stripping.

Primary Uses & Applications:

- Mining conveyor frame alignment
- Press machine weldment repair
- Crane boom connection joints
- Agricultural equipment assembly
- Shipbuilding structural compensation

How to Use:

1. **Rotate** screw shank to align offset vector with hole deviation.
2. **Insert** through misaligned plates.
3. **Torque** with **hex key** (e.g., H10 for M12) at **150-220 Nm** (M12).
4. **Clamp** without welding or re-drilling.
