Designed as part of ABUS’s renowned 300 Series, this bolt delivers exceptional strength, durability, and ease of use across a wide range of industrial, automotive, and security applications.

Key Design Features

• Threaded Length: 120 mm – provides ample engagement for robust fastening while maintaining a compact profile suitable for tight spaces.
• Diameter: 46 mm – strikes an optimal balance between load capacity and material efficiency, ensuring the bolt can withstand high shear forces without excessive bulk.
• Material Composition: High‑strength alloy steel treated with a protective coating to resist corrosion, rust, and wear in harsh conditions.
• Locking Mechanism: Integrated mechanical lock that prevents loosening under vibration or dynamic loads, eliminating the need for additional locking devices.
• Thread Standard: Metric M46 x 10 – compatible with a wide range of standard nuts and fittings, facilitating quick installation and interchangeability.
• Surface Finish: Powder‑coated or anodized options available to match aesthetic requirements while enhancing durability.

Applications Across Industries

The versatility of the ABUS 300/120 Locking Bolt makes it a preferred choice in numerous sectors:

• Aviation & Aerospace: Securing structural components where vibration resistance and weight efficiency are critical.
• Automotive: Mounting engine parts, chassis brackets, and suspension elements that demand high load tolerance.
• Construction & Civil Engineering: Fastening steel beams, columns, and safety railings in both temporary scaffolding and permanent structures.
• Marine & Offshore: Withstanding saltwater exposure and dynamic forces on hulls, decks, and offshore platforms.
• Security & Access Control: Anchoring locks, padlocks, and access panels where tamper resistance is essential.

Installation Guidelines

Proper installation maximizes the bolt’s performance. Follow these steps for optimal results:

1. Preparation: Clean the mating surfaces to remove oil, dust, and debris. Verify that the hole diameter matches the M46 specification.
2. Threading: Insert the bolt into the pre‑drilled hole, ensuring it aligns straight to avoid cross‑threading.
3. Tightening Sequence: Use a calibrated torque wrench. Apply torque in a progressive pattern (e.g., 0 → 25 % → 50 % → 75 % → 100 %) to evenly distribute clamping force.
4. Locking Verification: After full torque, confirm the mechanical lock engages by gently attempting to rotate the bolt. It should remain stationary.
5. Final Inspection: Check for any visible deformation or misalignment. Re‑torque if necessary after a brief settling period.

Maintenance & Longevity

The ABUS 300/120 Locking Bolt is engineered for low maintenance:

• Corrosion Protection: The powder‑coated finish resists oxidation. Periodic cleaning with mild detergent and drying prevents moisture buildup.
• Inspection Schedule: For critical applications, inspect the bolt every 12–24 months for signs of wear or loosening.
• Reusability: The bolt can be safely removed and reused if it remains free from cracks or excessive deformation. Re‑torque to original specifications upon reinstallation.

Performance Metrics

Engineered to meet stringent industry standards, the ABUS 300/120 Locking Bolt offers:

• Tensile Strength: Up to 1.2 MPa (depending on material grade), ensuring it can handle substantial axial loads.
• Shear Capacity: Designed for high shear environments, maintaining integrity under lateral forces.
• Vibration Resistance: The integrated lock prevents loosening even in high‑frequency vibration settings.
