Draper Expert Imperial Deep Socket Set on a Metal Rail, 3/8" Sq. Dr. (11 Piece)

Complete your AF socket coverage with the Draper Expert 11-Piece Imperial Deep Socket Set (D11AD/SR) — a professional-grade 3/8" drive deep socket set spanning 5/16" to 15/16" across all 11 standard imperial sizes, mounted on a durable metal storage rail for permanent, organised workshop installation.

Whether you're servicing classic British and American vehicles, working on agricultural machinery, maintaining older industrial equipment, or simply ensuring your workshop is equipped to handle both measurement systems without compromise, the D11AD/SR delivers the imperial deep socket coverage that metric-only sets cannot provide.

Imperial Coverage Where It Matters Most

AF fasteners remain a daily reality in workshops servicing older domestic vehicles, American imports, classic cars, vintage motorcycles, and agricultural or construction equipment manufactured to imperial standards. The D11AD/SR covers all 11 key AF sizes from 5/16" through to 15/16" in a single organised set — providing complete imperial deep socket coverage without gaps, and making it the natural complement to a metric deep socket set for workshops that need to work confidently across both systems.

Deep Socket Format for Full Fastener Engagement

Every socket in this set is a deep format, providing the extended internal clearance needed to fully engage imperial fasteners on extended bolts, threaded studs, and recessed nuts that standard-depth sockets cannot adequately seat on. On older vehicles and machinery — where corrosion, thread damage, and non-standard assembly are more common — the ability to achieve full, deep socket engagement is particularly important for safe, controlled fastener removal without risk of slippage or damage.

6-Point Socket Geometry

Each socket uses a 6-point drive profile, maximising contact with the flat faces of the fastener rather than its corners. This even distribution of torque significantly reduces the risk of rounding off AF fasteners — a critical advantage when working on older or corroded imperial fixings where the consequences of a slipped socket are both time-consuming and potentially costly to remedy.

Chrome Vanadium Steel — Hardened, Tempered and Micro Satin Finished

All 11 sockets are manufactured from chrome vanadium steel, hardened and tempered for lasting strength and durability across the full range of 3/8" drive applications. A micro satin chrome plate finish provides reliable corrosion resistance alongside a refined, low-glare surface appearance — practical in brightly lit workshop environments and more resistant to fingerprinting and light surface contamination than standard high-polish alternatives.

Knurled Ring for Confident Handling

Every socket features a knurled grip ring, providing a positive tactile surface for secure, one-handed socket handling during fitting and removal by hand. When working through a full sequence of imperial sizes on a repair job, the knurled ring makes socket selection and changes faster and more confident — even with oily, damp, or gloved hands.

Metal Storage Rail — Durable, Permanent Workshop Organisation

The D11AD/SR is supplied on a metal storage rail, offering the rigidity and long-term durability that a professional-grade imperial deep socket set warrants. The metal construction resists the flexing, cracking, and clip fatigue that plastic hanging rails develop over time under the weight and repeated use of a full deep socket set. Wall or pegboard mounted alongside a metric equivalent, the metal rail creates a permanent, professional, and immediately accessible imperial socket station within the workshop.

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.
