Grade 14.9 Ultra-high Strength Fine-pitch Bolts

Specially designed for high-load working conditions such as engines. The metallographic structure is optimized through cold heading forming, and the strength far exceeds that of ordinary bolts. Fine-pitch threads improve preload accuracy and anti-loosening ability, withstand engine explosion impact and alternating loads, ensure long-term stable connection of key components such as connecting rods, and guarantee the reliability and safety of the power system.
