Draper HI-TORQ® Metric Socket Set, 1/4" Sq. Dr. (47 Piece)

The Draper HI-TORQ® BD47M 47-Piece Metric Socket Set is a precision-focused 1/4" square drive toolkit engineered for the smaller fasteners and finer work that a 3/8" or 1/2" drive set simply can't handle with the same accuracy and control. Ideal for auto electricians, trim and interior technicians, motorcycle mechanics, electronics engineers, and anyone working on modern vehicles packed with small-fastener assemblies, this set delivers exceptional versatility in a compact, well-organised package.

The BD47M is built around 13 six-point HI-TORQ® sockets spanning an unusually wide range of 4–14mm — including the often-overlooked 4mm, 4.5mm, and 5.5mm sizes that are essential for instrument panels, ECU brackets, bodywork clips, and trim fasteners found throughout modern vehicles. Complementing these are 8 deep HI-TORQ® sockets (6–13mm) for recessed fasteners and longer-threaded fixings that standard sockets can't fully engage.

Every socket is precision-manufactured from chrome vanadium steel, hardened, tempered, and finished in a satin chrome matt finish for durability and corrosion resistance. The six-point socket geometry ensures maximum contact across fastener flats, reducing the risk of rounding on the small, easily damaged fasteners that 1/4" drive work frequently involves.

Where the BD47M truly sets itself apart is in its bit selection. A total of 20 screwdriver bits cover the four most common drive profiles encountered in modern automotive and engineering applications:

• 3 plain slot bits: 4, 5.5, 8mm
• 3 cross slot (Phillips) bits: No.1, No.2, No.3
• 6 hex (Allen) bits: 2, 3, 4, 5, 6, 8mm
• 8 Draper TX-STAR® Torx bits: T8, T10, T15, T20, T25, T27, T30, T40

The inclusion of a full TX-STAR® Torx bit range from T8 to T40 is a significant advantage — Torx fasteners are now ubiquitous across modern vehicle interiors, engine management systems, brake assemblies, seat mechanisms, and electronic components. Having these alongside hex and Phillips bits in a single integrated set removes the need for a separate bit set for Torx work.

The 72-tooth reversible ratchet with soft-grip handle and quick-release button delivers a fine 5° swing arc — particularly valuable at 1/4" drive where many fastening applications involve confined spaces with very little room for handle movement. The spinner handle accelerates fastener running once broken free, while the 100mm and 150mm extension bars and universal joint round out the accessory package with the reach and angle flexibility needed for deeper or more awkward access.

A 1/4" square drive to 1/4" hex bit adaptor ties the socket and bit sides of the set together, allowing you to use the full bit selection directly through your ratchet or extension bars — turning the BD47M into a single, unified fastening system.

The complete 47-piece set packs neatly into a moulded plastic storage case with dedicated locations for every piece, keeping the set organised and protecting the sockets and bits between uses.

Manufactured and tested in general accordance with DIN 3124 and ISO 2725-1 specifications, the BD47M HI-TORQ® delivers verified quality and dimensional accuracy across every component in the set.

What is a 1/4" drive socket set used for? A 1/4" square drive socket set is designed for smaller fasteners and precision work where a larger 3/8" or 1/2" drive would be unwieldy or risk over-torquing. Common applications include automotive trim and interior work, instrument clusters, ECU and electrical component brackets, motorcycle maintenance, bicycle servicing, and general electronics assembly. The smaller drive size provides greater control and access in tight spaces.

What sockets are included in the Draper BD47M? The BD47M includes 13 standard HI-TORQ® sockets (4–14mm) and 8 deep HI-TORQ® sockets (6–13mm), all on a 1/4" square drive. Notably, the standard socket range includes 4mm, 4.5mm, and 5.5mm sizes that are frequently omitted from general-purpose sets but are essential for modern vehicle fasteners.

What are TX-STAR® Torx bits and why are they important for automotive work? TX-STAR® is Draper's designation for Torx-compatible driver bits. Torx fasteners — identifiable by their six-pointed star-shaped recess — are now standard across a huge range of modern automotive applications, including brake callipers, seat runners, dashboard panels, engine covers, and electronic control units. The BD47M includes 8 TX-STAR® bits covering T8 through T40, providing comprehensive coverage for the Torx sizes most commonly encountered in automotive and engineering work.

What is the difference between the HI-TORQ® range and standard Draper socket sets? The HI-TORQ® designation indicates sockets engineered to withstand higher torque loads relative to their drive size, using chrome vanadium steel with hardening and tempering processes optimised for strength and durability. This makes them a more robust choice for professional or heavy-duty use compared to standard socket sets in the same drive size.

Why does the BD47M include sub-6mm socket sizes like 4mm and 4.5mm? Modern vehicles — particularly European models — make extensive use of very small metric fasteners on electronic components, interior trim, body panels, and sensor brackets. Sizes such as 4mm, 4.5mm, and 5.5mm are frequently required but absent from many 1/4" drive sets. The BD47M's inclusion of these sizes makes it significantly more useful for contemporary automotive work than sets that start at 6mm.

Can I use the screwdriver bits with the ratchet directly? Yes. The included 1/4" square drive to 1/4" hex bit adaptor connects the ratchet, extension bars, and universal joint directly to any of the 20 screwdriver bits in the set. This turns the BD47M into a fully integrated ratcheting screwdriver system alongside its socket capabilities.

What standards does the Draper BD47M meet? The BD47M is manufactured and tested in general accordance with DIN 3124 and ISO 2725-1 specifications, which govern dimensional accuracy and mechanical performance for 1/4" square drive socket sets and accessories.
