boen BN33257X 3/8-Inch Drive Impact Socket Set, 57-Piece SAE and Metric

For automotive work that calls for common SAE and metric fastener sizes, the boen BN33257X brings both systems together in one 3/8-inch drive set. Deep and shallow sockets cover a useful range for different fastener positions. A ratchet, extensions and adapters help you configure the set for the task at hand.

Getting the most from it

Use the marked sockets to select the size that matches the fastener, then choose a deep or shallow profile to suit the available clearance. The set covers SAE sizes from 5/16 to 3/4 inch and metric sizes from 8 to 22 mm, with five extra shallow 10 mm sockets for a frequently used size. Laser and stamped markings make size identification easier, while the six-point profile provides contact around the fastener for your work.

For automotive jobs where a straight approach is difficult, the universal joint helps angle the socket towards the fastener. The 3-, 6- and 10-inch extension bars add reach, and the included ratchet gives you a hand-operated option. A 3/8-inch hex-shank socket impact adapter is also part of the set for use with a power drill. Match the drive connection to your tool using the included 1/2-inch female-to-3/8-inch male and 1/4-inch female-to-3/8-inch male reducers.

Why it’s worth it

Rather than assembling SAE sockets, metric sockets and drive accessories separately, this set brings them together in a single organized kit. Its chrome vanadium steel sockets have a heat-treated construction and a black manganese phosphate coating. The blow-moulded case gives each piece a designated storage position, with size markings inside to help return the tools to their places between jobs. Two carabiners secure the case.

Buyer feedback highlights the readable size markings, useful selection and solid feel of the set. That feedback reflects customer impressions, while the practical benefit is easy to see in the layout: a broad mix of sizes and accessories is kept together for maintenance and repair tasks.
