US PRO 3479 14 Piece 1/4 Inch Drive 6 Point Deep Impact Socket Set

When precision and power meet compact design, you get a set built for impact performance without bulk. The US PRO 3479 14 Piece 1/4" Drive 6 Point Deep Impact Socket Set delivers a comprehensive range of commonly used metric impact sockets for engine work, interior fasteners, light-duty mechanical jobs, mobile service calls, and professional workshops.

Each socket in this set is manufactured from chromium molybdenum (CR-MO) steel, heat treated to a robust HRC45–47 to withstand impact forces while minimising wear. The 6 point profile enhances grip on fasteners to reduce rounding, and the short 50mm depth ensures easy access where space is limited. A protective black phosphate finish improves resistance to corrosion and everyday workshop wear.

The full set covers metric socket sizes from 4mm up to 15mm, all supplied on a handy storage rail for organisation and fast selection.
