Product Description

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.
