M24 x 80mm Track Chain Assembly Bolts & Nuts Kit - Grade 10.9 High Tensile Steel - Corrosion Resistant Coating - Compatible with Common Crawler Tractor Undercarriage Systems

Innovations:

  • Locking Tech: Integral spiral locking threads (Deutschhold® patent)

  • Material: Grade 12.9 super alloy (1,200 MPa yield)

  • Finish: Phosphating + wax impregnation

  • Design: Reduced-shank diameter for elasticity

Dynamic Load Performance:
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 Specs:

  • Fatigue limit: 425 MPa (R = -1)

  • Operating temp: -50°C to +150°C

  • Magnetism: <1.05 permeability (non-interfering with sensors)

Maintenance:
Inspect every 500 service hours. Discard if thread damage exceeds 10% or corrosion penetrates >5µm.
