Detailed Description
High Strength, High Toughness, and Excellent Fatigue Resistance:
Hexagon Head: Adopts a standard hexagonal head, compatible with special wrenches, enabling high-precision torque control to ensure consistent bolt preload.
Drilled Hole for Locking: Equipped with a drilled hole in the head or shank, allowing insertion of cotter pins or locking wires to effectively prevent loosening under vibration and impact conditions (e.g., aerospace equipment operating environments).
MJ Thread: Aerospace-specific anti-fatigue thread (complying with ISO 5855 and GB/T 43924 standards). The large arc design at the thread root significantly reduces stress concentration, with fatigue life 2-3 times higher than ordinary metric threads.
Main Applications: Key connection parts in aerospace (e.g., aircraft structural components, engine parts), and can also be extended to high-end equipment fields such as petroleum and locomotives.
