Features:
· High-quality material: Made of premium chromium-molybdenum steel with outstanding toughness, hardness, and impact resistance. Strong torque ensures the socket is not prone to wear, breakage, or deformation, providing high strength and stability.
· Durable precision: Overall high-temperature quenching via advanced heat treatment makes it sturdy and long-lasting. The surface is carbon black phosphated for rust prevention, wear resistance, and corrosion protection.
· Effortless operation: Hexagonal drive with arc inner corners provides a snug fit and stronger locking force. Concave bevel design, chip pier forming, and passivation processes ensure no burrs and prevent slipping during use.
