Draper Expert Multi-Drive® Metric Socket Set, 3/8" Sq. Dr. (42 Piece)

The Draper Expert Multi-Drive® 42-Piece Metric Socket Set is a comprehensive, professional-grade toolkit built for tradespeople and serious DIYers who demand versatility without compromise.

At the heart of this set is Draper's proprietary Multi-Drive® socket technology. Each socket is engineered to work with hexagon, bi-hexagon (both metric and AF), and Draper TX-STAR® fixings — meaning one socket can do the work of several. Whether you're working on stripped fasteners, awkward recesses, or mixed fixing types, this set has you covered without the need to switch tools.

All 26 sockets and 11 deep sockets are precision-manufactured from chrome vanadium steel, hardened and tempered for long-lasting durability, and finished with a micro satin chrome plating that resists corrosion even in demanding workshop environments. A knurled ring on each socket provides enhanced grip and confident handling.

The included 72-tooth reversible ratchet delivers a fine 5° swing arc — ideal for use in confined spaces — and features a quick-release button and a comfortable soft-grip handle for extended use. Three wobble extension bars (75mm, 150mm, and 250mm) and a universal joint further expand your reach and access in tight spots.

For added versatility, the set includes a hexagon bit adaptor, four TX-STAR® insert bits (T20, T25, T30, T40), and four hex insert bits (4, 5, 6, and 8mm), as well as two specialist HI-TORQ® spark plug sockets (10mm and 14mm).

Manufactured and tested in accordance with DIN3122 and ISO3315 specifications, this set meets the exacting standards required for professional use. Everything is stored in a rugged plastic storage case with a soft-grip handle, keeping your kit organised, protected, and portable on-site or in the workshop.

What's in the Box

What does Multi-Drive® mean on Draper sockets? Multi-Drive® refers to Draper's unique socket profile that allows a single socket to engage hexagon, bi-hexagon (metric and AF), and TX-STAR® fasteners. This is especially useful when working with worn or rounded fastener heads, as the socket can grip at more contact points.

What drive size is this socket set? This set uses a 3/8" square drive, which strikes the balance between the compact size of 1/4" drive and the higher torque capacity of 1/2" drive — making it ideal for general automotive, mechanical, and workshop tasks.

Is this socket set suitable for professional use? Yes. The D42MDSN/B is part of the Draper Expert range, which is manufactured and tested in accordance with DIN3122 and ISO3315 specifications. It is built from hardened and tempered chrome vanadium steel, making it suitable for both professional tradespeople and advanced home mechanics.

What is the tooth count on the included ratchet? The included ratchet has 72 teeth, giving a 5° swing arc. This allows it to be used effectively in confined or restricted spaces where a full ratcheting stroke isn't possible.

Does this set include spark plug sockets? Yes — the set includes two Draper Expert HI-TORQ® spark plug sockets in 10mm and 14mm sizes.
