11-Piece 3/8-Inch Drive Metric Deep Socket Set

This 11-piece set provides 3/8-inch drive deep metric sockets for automotive and general mechanical work. It suits technicians and DIYers who need extended reach on fasteners in tight spaces. The range covers 8 through 18mm for common metric hardware.

Heat-treated chrome vanadium steel

Sockets are forged from heat-treated chrome vanadium steel for strength under sustained torque. The high polish chrome finish resists rust and corrosion during repeated exposure to shop fluids and humidity. Six-point geometry grips fastener flats to reduce rounding when loads are held over time.

Laser etched markings

Each socket carries permanent laser etched size markings that remain legible after heavy use. The 6-point profile engages fastener sides cleanly, lowering the risk of slippage or rounding compared with 12-point alternatives. The set meets or exceeds ANSI and ASME performance standards for professional reliability.

Questions about this item

Do the 78224 sockets heat up or make noise during extended use?

Hand sockets produce no noise or heat during normal use; the chrome vanadium steel handles torque without generating warmth.

What drive ratchet or wrench is required to turn these 3/8-inch drive sockets?

Any 3/8-inch drive ratchet, breaker bar, extension, or torque wrench will engage the square drive on every socket in the set.

Will the 6-point 10-to-18mm deep sockets clear fasteners on older metric hardware?

The 6-point deep profile grips the flats of metric fasteners from 10 mm through 18 mm, reducing rounding on aged bolts.
