Product Description
M24 x 80mm Track Chain Assembly Bolts & Nuts Kit made from Grade 10.9 High Tensile Steel with corrosion resistant coating, compatible with common crawler tractor undercarriage systems.
Key Innovations
- Locking Technology: Integral spiral locking threads (Deutschhold® patent)
- Premium Material: Grade 12.9 super alloy (1,200 MPa yield)
- Protective Finish: Phosphating + wax impregnation
- Optimized Design: Reduced-shank diameter for enhanced elasticity
Performance Characteristics
Tested under SAE J2531 vibration profile (10-2,000Hz), these bolts maintain clamp load at >85% after 5M cycles. The spiral lock threads create radial interference, resisting loosening better than nylon inserts. Phosphated surface holds lubricant film, reducing fretting wear by 60%.
Compatibility
- Mine sites with blast vibrations
- Piling rigs/compactors
- Rail-mounted excavators
Technical Specifications
- Fatigue limit: 425 MPa (R = -1)
- Operating temperature range: -50°C to +150°C
- Magnetism:
Maintenance Guidelines
Inspect every 500 service hours. Discard if thread damage exceeds 10% or corrosion penetrates >5µm.
