boen BS-389074RB 3/8-Inch Drive Impact Socket Set, 74-Piece Metric and SAE

The 3/8-inch drive format gives this boen impact socket set a practical foundation for automotive, motorcycle and mechanical maintenance. Its 74 pieces bring metric and SAE sockets together with a ratchet and accessories, so you can switch between common fastener sizes without assembling a kit from separate tools.

Yellow embossed size markings are paired with laser markings on the sockets. The clear, dual-size identification helps you find the size you need quickly while moving between tasks.

A six-point socket design grips the flat sides of fasteners for a steady fit during tightening or removal. Deep and shallow sockets, extension bars and a universal joint also give you different ways to reach fasteners around components and in tighter spaces.

Practical tips

Choose a socket that fits the fastener securely, then use the 3/8-inch ratchet for controlled access. The six-point profile bears on the fastener’s flat sides, helping reduce the chance of rounding during use. When the fastener sits farther back, an extension bar can add reach, the universal joint helps approach at an angle. The ratchet’s 5° swing arc is useful when there is limited room to move the handle.

For a repair involving both metric and SAE fasteners, the two size ranges in one case make it easier to move between standards without changing tool sets. The two spark plug socket sizes add a dedicated option for spark plug work, while the screwdriver bits and adapters extend the kit’s usefulness across other maintenance tasks. It’s a more consolidated approach than building a selection of sockets and accessories one piece at a time.

Included in the pack

The set contains 28 metric and 16 SAE deep and shallow sockets, plus two spark plug sockets in 5/8-inch and 13/16-inch sizes. For driving and access, it includes a 72-tooth 3/8-inch ratchet, three 3/8-inch drive extension bars measuring 3, 6 and 10 inches, a 3/8-inch universal joint, and a 1/2-inch female-to-3/8-inch male socket adapter.

The remaining pieces are 20 1/4-inch driver screwdriver bits, a 1/4-inch female-to-3/8-inch male drill adapter and a 3/8-inch female-to-1/4-inch male impact bit holder. The bits cover Phillips, Torx, hex, Pozi and slotted profiles. A reinforced storage case with double-sided locking buckles keeps the set together for storage and carrying.

Should you buy it?

This set is suited to people who handle varied automotive, motorcycle, household or mechanical repairs and want metric and SAE sockets, impact-ready accessories and screwdriver bits in one organized kit. Its marked six-point sockets make size selection and fastener engagement more straightforward, while the extensions and joint offer useful reach options around crowded work areas. If you want a single set for a range of maintenance jobs rather than separate socket and accessory purchases, the boen kit brings those essentials together in a portable case.
