Industrial Eccentric Rivets/ Vibration Proof Fasteners/ Misalignment Tolerance/ Carbon Steel/ Batch Orders Guanbiao Hardware
Solve misalignment issues with our heavy-duty eccentric rivets. Compensate for hole offset in machinery, frames & structures. Carbon steel with zinc plating or Dacromet. High clamp force & vibration resistance.
Eliminate costly assembly headaches caused by misaligned holes with our robust **Eccentric Rivets**. Engineered with an offset (eccentric) shank design, these specialized fasteners allow for significant positional adjustment (±0.5mm to ±2.0mm+) during installation, compensating for manufacturing tolerances or frame distortions. Once set, they provide a permanent, high-clamp-force, vibration-resistant connection ideal for heavy machinery, structural frameworks, and transportation equipment.
TECHNICAL SPECIFICATIONS |

Primary Uses & Applications:
* Heavy machinery assembly (compensating for frame weld distortion).
* Truck & trailer chassis and subframe connections.
* Railway rolling stock assembly.
* Agricultural & construction equipment frames.
* Steel structure assembly (e.g., conveyors, cranes).
* Connecting components with pre-drilled holes prone to misalignment.
* Applications requiring vibration resistance & permanent joints.
Surface Treatment/Finishes:
* Heavy machinery assembly (compensating for frame weld distortion).
* Truck & trailer chassis and subframe connections.
* Railway rolling stock assembly.
* Agricultural & construction equipment frames.
* Steel structure assembly (e.g., conveyors, cranes).
* Connecting components with pre-drilled holes prone to misalignment.
* Applications requiring vibration resistance & permanent joints.
How to Use:
1. **Prepare Holes:** Drill holes in **both** materials to be joined to the nominal shank diameter (`d1`). Hole alignment tolerance is relaxed due to eccentricity.
2. **Insert Rivet:** Place the eccentric rivet through the holes. **Rotate the rivet shank** manually to align the eccentric portion optimally, compensating for the measured hole offset.
3. **Set Rivet:** Use a **heavy-duty hydraulic or pneumatic rivet setting tool** with the correct nosepiece/die for the rivet head style and size. The tool pulls the mandrel (if applicable) or directly forms the bucktail (blind end), permanently deforming the shank and clamping the materials with high force. The eccentric shank locks into position.
4. **Inspection:** Ensure the formed head is symmetrical and fills the die cavity, indicating a proper set.
