20-Piece Cr-V Steel Metric Socket Set with Extensions, Meeting ANSI Standards

SUPERIOR CR-V STEEL Constructed with heat-treated forged CRV material, our 1/2 inch impact socket set boasts high hardness and durability. It can withstand greater torque from impact tools, ensuring long-term reliability.

DURABLE & STAMPED MARKING Different from traditional black oxide coating, our BOEN allen socket set features black manganese phosphate coating for excellent corrosion and rust resistance. The stamped markings make all model numbers easy to read and identify.

FASTENED 6-POINT HEX DESIGN The recessed hexagonal nut design easily embeds into stubborn fasteners, preventing them from slipping. The 6-point lateral drive design prevents socket rounding under high torque, maintaining integrity without deformation.

METRIC & STANDARD SOCKET SET Includes sockets in sizes: 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 mm. Comes with a 3", 5", and 10" extension bar, 1/2" universal joint, and 3/8"-1/2" adapter. The extension bar helps access deep recessed bolts and nuts, suitable for vehicle maintenance.

STAY ORGANIZED & PORTABLE The heavy-duty blow-molded shell tightly wraps all parts, avoiding damage. A blow-molded enclosure with label slots facilitates easy storage and organization. Perfect for garage or outdoor use, suitable for fixing car tires and other maintenance tasks. The standard socket set meets the needs of the whole family.

QUALITY The deep socket set meets ANSI standards. All hex sockets have been rigorously tested to ensure optimal performance and durability.

NOTE If you receive a new set with a layer of oil on the sockets, it is a specially painted anti-rust oil for protection. Handle with care.
