Draper Expert Metric Coloured Deep Socket Set, 3/8" Sq. Dr. (12 Piece)

Speed up your workflow and eliminate size confusion with the Draper Expert 12-Piece Metric Coloured Deep Socket Set (D9MD/6PT/C/E) — a comprehensive 3/8" drive deep socket set spanning 8mm to 19mm, with every size finished in a unique identifying colour and fitted with a knurled grip ring for fast, confident handling in any working environment.

Colour Coded for Instant Size Identification

Time spent searching for the right socket is time wasted. The D9MD/6PT/C/E addresses this directly with a unique colour assigned to every socket size across the full 12-piece range, allowing instant visual identification without needing to read stamped size markings — particularly valuable in low-light working conditions, when hands are dirty, or when working at pace through a complex repair where multiple socket sizes are needed in quick succession.

The colour coding system works equally well whether sockets are stored on the hanging rail, laid out in a toolbox drawer, or arranged on a workbench — the right size is always immediately obvious at a glance.

Knurled Ring for Positive, Confident Grip

Every socket features a knurled grip ring, providing a positive tactile surface for secure finger-and-thumb handling during socket changes. On 3/8" drive sockets used across a wide range of detailed repair work, this is a practical detail that reduces fumbling and speeds up socket selection — especially useful when working with gloves or in awkward positions where dexterity is limited.

6-Point Socket Geometry

Each socket uses a 6-point drive profile to maximise contact with the flat faces of the fastener rather than its corners, distributing torque evenly and significantly reducing the risk of rounding off bolt heads and nuts. This is a particularly important advantage across the lower end of this size range — where smaller fasteners are more vulnerable to damage under poorly fitting or corner-loading tooling.

Deep Socket Format — Extended Reach Across All 12 Sizes

The deep socket format throughout this set provides the additional internal clearance needed to fully engage fasteners on extended bolts, threaded studs, and recessed nuts that standard-depth sockets cannot reach. Common across suspension components, engine ancillaries, exhaust fixings, and structural assemblies, the deep format makes the D9MD/6PT/C/E a more practically capable choice than a shallow equivalent across the full spectrum of automotive and engineering maintenance applications.

Chrome Vanadium Steel — Hardened, Tempered and Chrome Plated

All twelve sockets are manufactured from chrome vanadium steel, hardened and tempered for lasting durability and strength across the full range of 3/8" drive applications. A chrome plate finish provides reliable corrosion resistance and a clean, professional appearance, ensuring the set retains its quality and performance through years of regular workshop use.

Complete Coverage from 8mm to 19mm

Spanning 8mm through to 19mm in unbroken single millimetre increments, this set covers the complete core metric range for passenger vehicle servicing, light commercial maintenance, and general engineering — with every size present and accounted for so there are no gaps to send you searching for a missing socket mid-job.

Plastic Hanging Rail — Workshop and Toolbox Ready

The full set is supplied on a plastic hanging rail that showcases the colour coding system to best effect, keeping every socket organised, clearly visible by both size and colour, and immediately to hand. The rail can be wall or pegboard mounted for open workshop display, or laid flat inside a toolbox drawer — providing flexible, space-efficient storage in any environment.

Manufactured to DIN3122 and ISO3315 Standards

The set is manufactured and tested generally in accordance with DIN3122 and ISO3315 specifications, providing professional users with confidence in the quality, consistency, and performance of every socket.
