D-Series High-Temperature Bolts specifically engineered for Liebherr PR736 and PR746 Bulldozers. These turbocharger connecting bolts feature exceptional high-heat resistance and oxidation resistance properties.

Constructed from nickel-based superalloy material, these bolts maintain stable mechanical properties in environments exceeding 700℃. They offer excellent oxidation resistance and resist embrittlement during prolonged use. With 5g grade thread precision, they ensure a perfect fit with turbocharger flange surfaces for optimal sealing performance and exhaust gas leakage prevention.

The high-temperature surface coating effectively isolates heat transfer and minimizes stress deformation caused by temperature fluctuations. Rigorous high-temperature fatigue testing confirms these bolts retain high strength through repeated thermal cycles, making them essential for turbocharger safety in high-power bulldozer operations.
