Draper Expert Metric Deep Socket on a Metal Rail, 1/2" Sq. Dr. (15 Piece)

The definitive 1/2" drive deep socket set for the professional workshop — the Draper Expert 15-Piece Metric Deep Socket Set (H15MD/SR) delivers an unbroken run of deep sockets from 10mm to 24mm, mounted on a durable metal socket rail designed for secure, permanent workshop storage. Combining the extended reach capability of deep socket engineering with professional-grade chrome vanadium construction and a premium micro satin finish, this is a set built to perform reliably and stay organised through years of demanding daily use.

Deep Sockets Across the Full 1/2" Drive Range

The 1/2" square drive is the workhorse of the professional automotive and engineering workshop, handling the higher torque demands of wheel nuts, suspension components, drivetrain fixings, and larger structural fasteners. The D15MD/SR pairs this high-torque capability with a deep socket format throughout — providing the additional internal clearance needed to fully engage fasteners on extended bolts, threaded studs, and recessed nuts that standard-depth sockets cannot adequately reach.

Across the 10mm to 24mm range in 1/2" drive, the deep format is particularly valuable for suspension overhauls, exhaust system work, engine component removal, and chassis maintenance — where protruding threads, long bolt assemblies, and deeply recessed fixings are routinely encountered and standard-depth sockets frequently fall short.

Chrome Vanadium Steel — Hardened, Tempered and Micro Satin Finished

All 15 sockets are manufactured from chrome vanadium steel, hardened and tempered for the long-term strength, toughness, and fatigue resistance demanded by professional 1/2" drive applications. A micro satin chrome plate finish delivers reliable corrosion protection alongside a refined, low-glare surface that outperforms standard polished chrome in bright workshop lighting — reducing reflective distraction during detailed work and offering better resistance to fingerprinting and light surface contamination through regular use.

Knurled Ring for Fast, Confident Socket Changes

Each socket features a knurled grip ring, providing a positive tactile surface for secure, one-handed socket handling when fitting and removing by hand. Across a 15-piece set used intensively in a professional environment, the knurled ring meaningfully speeds up socket selection and changes throughout the working day — maintaining confident grip even with oily, damp, or gloved hands when working at pace through a complex repair.

Metal Socket Rail — Secure, Permanent Workshop Storage

The H15MD/SR is supplied on a metal socket rail, providing the rigidity, durability, and permanence that a professional 1/2" drive deep socket set of this quality demands. The metal construction handles the additional weight of larger 1/2" drive deep sockets without the flexing, cracking, or clip fatigue that plastic hanging rails develop over time under sustained load. Wall or pegboard mounted, the metal rail keeps all 15 sockets permanently organised by size, immediately accessible, and securely held throughout the working day — making it a functional fixture in any well-equipped professional workshop.

Complete and Unbroken — 10mm to 24mm

With 15 deep sockets covering every millimetre from 10mm to 24mm, this set provides thorough 1/2" drive metric deep socket coverage across the core range for passenger vehicle servicing, light and heavy commercial maintenance, and general engineering applications. The inclusion of 23mm and 24mm — sizes frequently omitted from comparable sets — ensures complete coverage for the larger fastener dimensions commonly encountered on suspension assemblies, axle components, and structural fixings.

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 workshop applications.
