Grade 14.9 Ultra-High Strength Fine Thread Bolts
Specially designed for high-load conditions such as engines, these bolts optimize the metallographic structure through cold heading, offering strength far exceeding that of ordinary bolts. The fine thread design improves pre-tightening precision and anti-loosening performance, enabling them to withstand engine explosive impacts and alternating loads. This ensures the long-term stable connection of critical components like connecting rods, guaranteeing the reliability and safety of the powertrain system.
