YATO YT-1055 1/2 inch Drive Impact Socket Set, 15-Piece Metric, 10-32 mm, CrMo Steel, Black Phosphate, DIN 3121

Professional mechanics and serious DIYers working on suspension, engine, or wheel fasteners need sockets that can withstand the punishment of high-torque impact wrenches. The YATO YT-1055 impact socket set delivers exactly that, with 15 metric 6-point sockets covering sizes from 10 mm to 32 mm. Each socket is forged from chrome molybdenum steel (CrMo) and finished with a black phosphate coating for superior corrosion resistance and a secure grip. The 1/2-inch square drive fits standard impact tools, and the sockets meet DIN 3121 standards for reliable performance. Packed in a blow-moulded plastic case, this set keeps your tools organized and protected, whether in a busy workshop or a mobile service van.

Why choose it

Impact sockets must absorb extreme shock without cracking or deforming. The CrMo construction and black phosphate finish give these sockets high impact resistance and long service life. The 6-point profile grips fasteners securely, reducing the risk of rounding off nuts and bolts, even under high torque. The set covers the most common metric sizes used in automotive and industrial applications, making it a versatile addition to any tool collection.

Ideal use cases

• Automotive repair: lug nuts, suspension bolts, engine mounts, and more
• Industrial maintenance: heavy machinery and equipment fastening
• Professional workshops and mobile mechanics requiring a portable, organized set
• DIY enthusiasts working on cars, trucks, or farm equipment with impact wrenches

Good to know

The sockets are designed for use with impact wrenches and drivers, not for hand ratchets. The black phosphate coating provides corrosion resistance and a non-reflective surface. The blow-moulded case has clearly marked size slots for quick identification and secure storage. Always use appropriate personal protective equipment when operating impact tools.
