Draper Combined MM/AF Deep Socket and Ratchet Set, 1/2" Sq. Dr. (20 Piece)

Cover both metric and imperial fasteners in a single organised set with the Draper 20-Piece Combined MM/AF Deep Socket and Ratchet Set (HD20AMD/PR) — a versatile 1/2" drive deep socket set that pairs nine metric and nine imperial sockets with a premium 72-tooth quick release ratchet and 125mm extension bar, making it the ideal choice for workshops and technicians who regularly work across both measurement systems.

Metric and Imperial — One Set Does Both

Many automotive, agricultural, and industrial environments demand the ability to work across both metric and AF (across flats / imperial) fastener systems — particularly when servicing older British and American vehicles, classic cars, agricultural machinery, and imported equipment where mixed fastener standards are the norm rather than the exception.

The HD20AMD/PR eliminates the need to maintain two separate socket sets, bringing together nine metric sizes from 10mm to 22mm and nine imperial sizes from 3/8" to 7/8" in a single unified set. The result is comprehensive dual-standard coverage without duplicating tools, cost, or storage space.

Deep Socket Format for Extended Reach

Every socket in this set is a deep format, 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. Deep sockets are an essential capability for suspension work, exhaust systems, engine components, and chassis fixings where fasteners commonly project well beyond the face of the nut — making the HD20AMD/PR a more practically capable choice than an equivalent shallow socket set for demanding workshop use.

Chrome Vanadium Steel — Hardened, Tempered and Satin Finished

All 18 sockets are manufactured from chrome vanadium steel, hardened and tempered for long-term strength and durability across the full range of 1/2" drive applications. A satin chrome plate finish delivers reliable corrosion resistance and reduces surface glare during use — a practical advantage in well-lit workshops and under vehicle inspection lighting during extended repair sessions.

72-Tooth Reversible Ratchet with Quick Release

The included 72-tooth reversible ratchet provides a fine 5° engagement arc, enabling smooth, controlled operation and productive use even in the most confined working spaces where a full swing simply isn't achievable. At 72 teeth, this ratchet delivers a noticeably more refined and responsive feel than the lower tooth-count mechanisms typically found in entry and mid-level sets.

A quick release button allows fast, confident one-handed socket changes throughout the job, while the soft grip handle provides comfort during extended use and a secure hold in oily or damp conditions.

125mm Extension Bar

The included 125mm extension bar adds the reach needed to access fasteners set within engine bays, beneath trim panels, and inside structural assemblies — extending the practical capability of the set from the outset without requiring additional accessory purchases.

Plastic Hanging Rack — Organised for Workshop and Toolbox

The complete 20-piece set is supplied on a plastic hanging rack, keeping every socket clearly laid out and immediately identifiable by size. The rack can be wall or pegboard mounted for open workshop storage, or laid flat inside a toolbox drawer — providing practical, flexible storage without the bulk and weight of a traditional moulded carry case.

Manufactured to DIN3122 and ISO3315 Standards

The ratchet is manufactured and tested generally in accordance with DIN3122 and ISO3315 specifications — internationally recognised standards for ratchet handle construction and performance, providing professional users with confidence in the tool's quality, consistency, and suitability for demanding applications.
