Draper Expert Multi-Drive® Deep Socket Set, 3/8" Sq. Dr. (12 Piece)

Reduce your toolbox footprint without sacrificing capability with the Draper Expert 12-Piece Multi-Drive® Metric Deep Socket Set (D9MD/MDS/E) — a 3/8" drive deep socket set built around Draper Expert's innovative Multi-Drive® profile that replaces the need for separate hex, bi-hex, spline, and TX-STAR® socket sets with a single unified collection spanning 8mm to 19mm.

What Makes Multi-Drive® Different?

The Draper Expert Multi-Drive® internal profile is engineered to engage and drive multiple fastener types from a single socket — including metric and imperial hexagon, bi-hexagon, spline, and Draper TX-STAR® fixings. Where a conventional 6-point or 12-point socket is locked to a single fastener format, a Multi-Drive® socket handles the full spectrum of drive systems encountered across modern and classic vehicles, industrial equipment, and precision engineering applications.

For workshops and technicians who regularly encounter mixed fastener systems across different vehicle platforms or equipment types, the D9MD/MDS/E delivers a genuinely more efficient solution — fewer sets to maintain, fewer gaps in capability, and a single tool selection process regardless of what fastener type is in front of you.

Deep Socket Format for Maximum Application Range

Every socket in this set is a deep format, providing the extended internal clearance needed to fully engage fasteners on extended bolts, threaded studs, and recessed nuts that standard-depth sockets cannot adequately seat on. Across the 8mm to 19mm range — covering the core metric sizes for automotive, engineering, and general maintenance work — this additional depth transforms the practical versatility of the set, enabling full engagement across suspension assemblies, engine components, exhaust fixings, and structural fasteners that regularly involve protruding threads and recessed access points.

Knurled Ring for Positive Handling

Every socket features a knurled grip ring, providing a positive, tactile surface for confident one-handed socket changes when fitting and removing by hand. Across the varied 3/8" drive applications this set is designed for, the knurled ring makes a meaningful practical difference — reducing fumbling during fast-paced repair work and ensuring secure handling even with oily or gloved hands.

Chrome Vanadium Steel — Hardened, Tempered and Micro Satin Finished

All twelve sockets are manufactured from chrome vanadium steel, hardened and tempered for lasting strength, toughness, and durability across the full range of 3/8" drive applications. A micro satin finish provides reliable corrosion resistance alongside a refined, low-glare surface appearance that performs better in bright workshop lighting than standard high-polish alternatives, and resists fingerprinting and light surface contamination during regular use.

Complete Coverage from 8mm to 19mm

Spanning 8mm through to 19mm in unbroken single millimetre increments, this set covers every key metric size across the core range for passenger vehicle servicing, light commercial maintenance, and general engineering work — with the added Multi-Drive® capability meaning each socket in the range works equally across hex, bi-hex, spline, and TX-STAR® fasteners without any need for additional specialist sets.

Plastic Hanging Rail — Workshop and Toolbox Ready

The complete 12-piece set is supplied on a plastic hanging rail, keeping every socket organised, clearly laid out by size, and immediately accessible. The rail can be wall or pegboard mounted for open workshop display, or laid flat inside a toolbox drawer — providing practical, flexible storage that keeps the set organised and ready for use 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 across demanding professional and domestic applications.
