Draper Expert Metric Socket Set, 3/8" Sq. Dr. (36 Piece)

The Draper Expert D36MN/SG 36-Piece Metric Socket Set delivers a well-balanced combination of standard and deep sockets, a wide range of drive accessories, and professional-grade build quality — making it an outstanding choice for vehicle technicians, engineers, and trade users who need dependable tools across a broad range of applications.

The set brings together 15 standard metric sockets, 12 deep sockets, and 3 spark plug sockets on a 3/8" square drive, giving you coverage from 6mm right through to 22mm in both standard and deep profiles. Whether you're removing wheel bolts, working on suspension components, or tackling recessed engine fasteners, the D36MN/SG has the socket for the job.

All sockets are precision-engineered from chrome vanadium steel, hardened, tempered, and finished with Draper's distinctive micro satin chrome plating for long-lasting corrosion resistance and a professional appearance. The six-point socket geometry maximises contact across the full flats of each fastener, significantly reducing the risk of rounding — particularly valuable on older, corroded, or over-torqued fixings. The knurled grip ring on every socket ensures confident one-handed positioning, even when working in awkward overhead or confined spaces.

Where the D36MN/SG really distinguishes itself is in its drive accessory range. Three wobble extension bars — 75mm, 150mm, and a generous 250mm — provide unmatched reach flexibility, letting you access deeply recessed fasteners that shorter extensions simply can't touch. The wobble feature adds off-axis flexibility of up to approximately 15°, removing the need to fight for a straight-line approach to every bolt. Add in the sliding T-bar and universal joint, and you have a complete system for applying controlled torque at virtually any angle or depth.

The 72-tooth reversible ratchet rounds off the set with its soft-grip handle, quick-release button, and fine 5° swing arc — ideal for rapid fastener removal and installation in tight spaces where a full handle sweep isn't possible.

All 36 pieces store securely in a tough blow-moulded plastic storage case fitted with a soft-grip handle, keeping your toolkit organised, protected, and easy to carry between jobs.

Manufactured and tested in general accordance with DIN3122 and ISO3315 specifications, the D36MN/SG is part of Draper's Expert range — built to the higher standards demanded by professional and trade environments.

What sockets are included in the Draper Expert D36MN/SG set? The D36MN/SG includes 15 standard metric sockets (6–19mm and 22mm), 12 deep metric sockets (8–19mm and 22mm), and 3 spark plug sockets (10, 12, and 14mm), all on a 3/8" square drive.

What is the difference between the D36MN/SG and the D42MN/SG? The D42MN/SG offers a wider socket range extending up to 24mm with more sockets in both standard and deep profiles, plus a 1/2" to 3/8" drive adaptor. The D36MN/SG trades some socket count for a more comprehensive accessory selection, notably adding a longer 250mm wobble extension bar and a sliding T-bar — making it the stronger choice where reach, leverage, and drive flexibility are the priority.

What is a sliding T-bar and when would you use it? A sliding T-bar is a drive accessory that fits into your extension bar or directly onto the socket drive. The handle slides left and right along the bar, allowing you to centre the drive over the fastener for straight-line torque, or offset it for a longer lever arm when greater turning force is needed. It's particularly useful for loosening tight fasteners without a ratchet, or for rapidly spinning out bolts once broken free.

Why does the D36MN/SG include three extension bar lengths? Different tasks call for different levels of reach. The 75mm bar handles most standard under-bonnet jobs, the 150mm bar reaches deeper into engine bays and chassis, and the 250mm bar provides extended access to fasteners buried deep within bodywork, transmission tunnels, or suspension assemblies. Having all three lengths in one set eliminates the need to purchase extensions separately.

What are wobble extension bars? Wobble extension bars feature a flexible drive connection that allows the socket end to pivot up to approximately 15° off-axis. This means you can engage a fastener even when a perfectly straight approach isn't possible — invaluable in crowded engine bays, tight chassis areas, and anywhere with restricted access.

Is the Draper Expert D36MN/SG suitable for professional mechanics? Yes. The D36MN/SG is part of Draper's Expert range, built to DIN3122 and ISO3315 standards using chrome vanadium steel with hardened and tempered construction. Its combination of deep sockets, multi-length wobble extensions, and sliding T-bar makes it particularly well-suited to professional automotive and engineering applications.
