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