Draper Expert HI-TORQ® Metric Socket Set on a Metal Rail, 3/8" Sq. Dr. (15 Piece)

The benchmark for 3/8" drive socket organisation in a professional workshop — the Draper Expert HI-TORQ® 15-Piece Metric Socket Set (D15M/SR) delivers an unbroken run of 15 metric sizes from 8mm to 22mm, mounted on a chrome plated steel rack built for permanent workshop installation. Combining the quality of Draper Expert's HI-TORQ® 6-point socket engineering with a premium metal storage solution, this is a set designed to perform reliably and look the part for years of daily professional use.

HI-TORQ® 6-Point Socket Geometry

Every socket in the D15M/SR is built around Draper Expert's HI-TORQ® 6-point profile — engineered to engage the flat faces of a fastener rather than its corners. By distributing torque evenly across the full face of the bolt head or nut, the HI-TORQ® design significantly reduces the risk of rounding off fasteners, providing a more secure and controlled drive throughout the full 8mm to 22mm size range. This is particularly valuable at the higher torque end of the 3/8" drive range, where the risk of fastener damage is greatest under poorly fitting tooling.

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 and resilience expected from a professional-grade socket set. A micro satin chrome plate finish delivers reliable corrosion protection alongside a refined, low-glare surface that performs well in brightly lit workshop environments — reducing reflective distraction during detailed work and resisting fingerprinting and surface contamination better than standard high-polish alternatives.

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 daily in a busy workshop, this detail meaningfully speeds up socket selection and changes — maintaining confident grip even with oily, damp, or gloved hands throughout the working day.

Chrome Plated Steel Rack — A Permanent Workshop Solution

The D15M/SR is supplied on a chrome plated steel rack that sets this set apart from the plastic hanging rail alternatives common across most socket sets in this category. The chrome plated steel construction offers superior rigidity, durability, and long-term resistance to the flexing, cracking, and clip fatigue that plastic rails can develop under the weight and repeated use of a full 15-socket set. Wall or pegboard mounted, the steel rack presents the complete set in a clean, professional arrangement that becomes a permanent, functional feature of the workshop — keeping every socket visible, organised, and immediately to hand throughout the working day.

Complete and Unbroken — 8mm to 22mm

With 15 sockets covering every size from 8mm through to 22mm in single millimetre increments, the D15M/SR provides the most complete 3/8" drive metric coverage available at this format — extending beyond the 19mm ceiling of most comparable sets to include the 20, 21, and 22mm sizes commonly required for larger automotive and engineering fasteners. No gaps, no missing sizes, no compromises.

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.
