About this product

A 12-piece extra shallow magnetic socket set for 3/8in drive tools, covering metric sizes from 8mm to 21mm. Built for tighter access where a standard socket may be too deep, it gives a practical option for everyday fastening work in the garage, workshop or on general repair jobs.

Used for vehicle maintenance, servicing, fitting work and DIY repairs, this set is handy when working around restricted areas with limited clearance. The magnetic design helps hold fasteners in place during removal or refitting, which can be useful when working in awkward positions, around engine bays, or where dropped nuts and bolts slow the job down.

The set includes 12 commonly used metric sizes: 8, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 and 21mm. Its extra shallow profile is the key feature here, helping reach fixings where space above the fastener is limited. Internal magnets are built into each socket, and the supplied storage rail keeps the set together between jobs and makes it easier to see the size you need at a glance. The size spread covers a useful range for regular maintenance and repair work without taking up much room in the tool box.
