Amount torque and special alloy steel which raises the endurance and wear resistance are adopted.
Wear in the hexagonal part is stopped by high heat-treatment and hard chromium electroplating processing.
Though it was high-strength, the toughness (It was difficult to fracture.) was raised, and certain work and safety were improved.
