Forged from high-quality iron, it has high strength and hardness, high elasticity and fatigue limit, strong clamping and high torque
C-shaped structure design, the torque is 10%-20% higher than ordinary wrenches. The wrench is hardened by high temperature quenching, which has high hardness and durability
Thicker head, firm fixation, thicker head firmly clamps objects, not easy to slip, black surface, not easy to rust
