Large Scaled Hinged Bolt Fastener High Strength Link Swing Bolt Cast Iron / Steel

Product Profile: High-Strength Articulated Fastener

A critical fastener for articulated structures in engineering machinery, vehicle chassis, and aerospace applications. Designed to balance robust connection strength, fatigue resistance, and articulation flexibility while transmitting heavy loads efficiently.

Key Features:
✔ Ultra-High Strength – Tensile strength ≥900 MPa | Shear strength ≥600 MPa
✔ Precision Threads – 6g grade accuracy with fine-pitch design (e.g., M20×1.5) for anti-loosening
✔ Optimized Geometry – Transition fillet R≥2mm to minimize stress concentration
✔ Versatile Head Options – Hexagon or countersunk heads for diverse installation needs

Technical Specifications:

• Materials: 40Cr, 35CrMo high-strength alloy steel

• Heat Treatment: Quenched & tempered to HRC32-36

• Thread Standard: 6g grade fine-pitch

• Strength: Tensile ≥900 MPa | Shear ≥600 MPa

Applications:

• Engineering machinery articulations

• Vehicle chassis connections

• Aerospace structural linkages

• Heavy-duty rotating or pivoting systems

Why Choose This Fastener:

• Engineered for extreme dynamic loads and vibrations

• Fine-pitch threads enhance self-locking and safety

• Fatigue-resistant design extends service life

• Critical for applications where articulation cannot compromise strength
