Draper Expert Metric Socket Set, 1/4" Sq. Dr. (30 Piece)

The Draper Expert B30MN/SG 30-Piece Metric Socket Set is a drive-accessory-focused 1/4" square drive toolkit that places equal emphasis on socket depth coverage and reaching versatility — making it the strongest pure-socket option in the Draper Expert 1/4" range for technicians and engineers who prioritise access capability over screwdriver bit variety. With 13 standard sockets, 10 deep sockets, and a six-piece drive accessory package that includes three wobble extension bars, a sliding T-bar, spinner handle, and universal joint, the B30MN/SG is built for professionals who demand complete fastening reach from a compact drive size.

The standard socket complement spans 13 six-point metric sockets from 4–14mm — a wider top-end reach than many comparable 1/4" drive sets, with the 14mm size bridging the gap towards 3/8" drive territory for interior bolts, wheel arch fixings, and suspension-adjacent fasteners on smaller vehicles. The range also includes the frequently omitted 4.5mm and 5.5mm intermediate sizes, ensuring complete coverage of the sub-6mm fasteners found on modern vehicle electronics, instrument panels, ECU brackets, sensor housings, and bodywork trim fixings.

The 10 deep sockets — spanning 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14mm — are the standout feature of the B30MN/SG's socket selection. Ten deep socket sizes across a 5–14mm range represents one of the most complete deep socket complements available at 1/4" drive. Where most compact sets include four to six deep sockets covering only the most common sizes, the B30MN/SG ensures deep-reach capability is available across virtually the entire working range — from the 5mm deep socket needed for recessed instrument fasteners and panel fixings right through to 14mm for longer-threaded bolts on mechanical assemblies. For technicians whose work regularly involves recessed fasteners, long studs, or captive nuts, this depth of deep socket coverage eliminates the most common access limitation of compact 1/4" drive kits.

All 23 sockets are precision-manufactured from chrome vanadium steel, hardened, tempered, and finished to Draper's Expert-grade micro satin chrome — a refined, low-glare surface treatment that reduces reflective eye fatigue in brightly lit workshops, fingerprints less readily than high-polish alternatives, and delivers excellent long-term corrosion resistance. The knurled ring on each socket provides a positive, tactile grip for confident one-handed positioning in oily, greasy, or gloved conditions, and the six-point geometry ensures maximum contact across fastener flats — minimising rounding risk across the full size range.

The drive accessory package is among the most complete available in a focused socket-only 1/4" drive set. Six accessories deliver thorough control over reach, angle, and torque application:

• 72-tooth reversible ratchet with soft-grip handle and quick-release button — a fine 5° swing arc for productive fastener engagement even in the most restricted spaces
• Spinner handle for rapid, low-fatigue fastener running once broken free
• Three wobble extension bars at 50mm, 100mm, and 150mm — the complete three-bar complement covering shallow, mid-depth, and deep access with off-axis flexibility built in at every length
• Sliding T-bar — for high-leverage breakaway force on stubborn or corroded fixings, or rapid free-spinning without a ratchet
• Universal joint — for indirect-angle fastener access in confined or obstructed spaces

The presence of all three wobble extension bar lengths is a practical advantage that sets the B30MN/SG apart from sets that offer only two. Having 50mm, 100mm, and 150mm bars to hand means the right extension is always available without resorting to stacking — which reduces rigidity and torque feel — and the wobble feature at each length removes the need to substitute a universal joint for moderate off-axis deviations. Combined with the sliding T-bar, the B30MN/SG offers more torque application options than the majority of 1/4" drive sets at this size.

The complete 30-piece set is housed in a tough blow-moulded plastic storage case with dedicated recesses for every socket and accessory, keeping the set complete, organised, and ready for workshop use or transport between jobs. As part of Draper's Expert range, the B30MN/SG is manufactured and tested in general accordance with DIN3122 and ISO3315 specifications — quality verified to the standards demanded by daily professional use.

What sockets are included in the Draper Expert B30MN/SG? The B30MN/SG includes 13 standard six-point metric sockets (4–14mm, including 4.5mm and 5.5mm) and 10 deep metric sockets (5–14mm) — 23 sockets in total, all on a 1/4" square drive with chrome vanadium steel construction, micro satin chrome finish, and knurled grip rings.

Why does the B30MN/SG include 10 deep sockets when many comparable sets include only four to six? The B30MN/SG is specifically designed for technicians and engineers whose work frequently involves recessed fasteners, long studs, and captive nuts that standard sockets cannot fully engage. By providing deep socket coverage across 5–14mm — essentially the full working range of the standard socket selection — the set eliminates the most common access limitation of compact 1/4" drive kits without requiring the user to supplement with a separate deep socket set. It is the natural choice for professionals who find deep socket gaps in standard sets a regular frustration.

What is the difference between the Draper Expert B30MN/SG and the B44MN/SG? The B44MN/SG includes fewer deep sockets (6 vs 10) but adds 21 direct-fit socket bits across plain slot, Phillips, Pozidriv, hex, and TX-STAR® Torx profiles — making it the stronger choice for technicians who need integrated screwdriving capability alongside their sockets. The B30MN/SG trades the bit selection for a far more comprehensive deep socket range and all three wobble extension bar lengths, making it the better choice for work where recessed fastener access and drive versatility are the priority over screwdriver bit coverage.

What is the practical difference between the 50mm, 100mm, and 150mm wobble extension bars? The 50mm bar is suited to standard shallow applications where a small amount of additional reach is needed beyond the ratchet alone. The 100mm bar extends reach into engine bays, instrument panels, and moderately deep assemblies. The 150mm bar provides the maximum reach in the set, accessing deeply buried fasteners inside door cavities, transmission tunnels, bulkheads, and heavily assembled components. Having all three lengths eliminates the need to stack bars — which reduces stability and torque feel — and ensures the optimal extension length is always available for each specific job.

What does the sliding T-bar add to a 1/4" drive socket set? The sliding T-bar provides a crossbar handle that connects directly to the 1/4" square drive. Positioned centrally it applies straight-line torque; offset to one side it creates a lever arm for breaking out stubborn or corroded fasteners without a ratchet. It also allows rapid free-spinning of fasteners using both hands — significantly faster than ratcheting for the running portion of a bolt. For technicians removing multiple similar fasteners in sequence, the T-bar dramatically reduces the time spent on the free-running portion of each fastener.

Why does the B30MN/SG extend to 14mm when most 1/4" drive sets stop at 13mm? The 14mm socket — in both standard and deep profiles — extends the B30MN/SG's coverage into fastener sizes more commonly associated with 3/8" drive, including interior bolts, wheel arch liner fixings, and certain suspension-adjacent fasteners on smaller vehicles. Having 14mm available at 1/4" drive provides a more compact and manoeuvrable option for these fasteners in tight spaces where a 3/8" ratchet would be difficult to swing.

Is the Draper Expert B30MN/SG suitable for professional use? Yes — the B30MN/SG is part of Draper's Expert range, built to DIN3122 and ISO3315 specifications using chrome vanadium steel with micro satin chrome finish and knurled socket rings. Its combination of 10 deep sockets, three wobble extension bars, sliding T-bar, and spinner handle makes it a particularly strong choice for professional vehicle technicians, engineers, and workshop users who regularly work with recessed fasteners and need maximum access flexibility from a compact drive size.
