Draper Expert Metric Socket Set, 1/4" Sq. Dr., Green (25 Piece)

The Draper Expert B25MN/SG/GREEN 25-Piece Metric Socket Set is a compact, access-focused 1/4" square drive toolkit that delivers an impressive combination of standard and deep socket coverage alongside a well-considered drive accessory package — all presented in a distinctive green colour-coded storage case that makes it instantly identifiable on any tool trolley or workshop bench. For professionals who organise their toolkit by drive size or set type, the green colourway provides a reliable visual reference that eliminates time wasted searching through cases at the start of every job.

Despite its 25-piece count, the B25MN/SG/GREEN punches well above its weight in terms of capability. 12 standard six-point sockets span 4–13mm — including the frequently omitted 4.5mm and 5.5mm intermediate sizes essential for the small fasteners found on modern vehicle electronics, sensor brackets, ECU housings, instrument panels, and bodywork trim. Alongside these, 7 deep sockets covering 5, 6, 7, 8, 10, 11, and 13mm provide recessed-fastener reach across the most commonly encountered deep-access sizes in automotive and engineering work. The combination of standard and deep profiles in a set of this size makes the B25MN/SG/GREEN a genuinely capable compact kit rather than a basic starter set.

Every socket carries the hallmarks of the Draper Expert range: chrome vanadium steel construction, hardened, tempered, and finished to the distinctive micro satin chrome surface treatment. The low-glare micro satin finish reduces reflective eye fatigue under workshop lighting, fingerprints less readily than high-polish alternatives, and provides excellent long-term corrosion resistance — all practical advantages for a tool used in daily professional environments. The knurled ring on each socket ensures confident one-handed positioning in oily, greasy, or gloved conditions, and the six-point geometry maximises contact across fastener flats to minimise rounding risk on the small, easily damaged fixings that 1/4" drive work regularly involves.

The drive accessory package delivers strong reach and torque flexibility for a set of this size. Five accessories cover the full range of standard access requirements:

• 72-tooth reversible ratchet with soft-grip handle and quick-release button — a fine 5° swing arc for productive fastener engagement in the tightest spaces
• Spinner handle for rapid, low-fatigue fastener running once broken free
• Two wobble extension bars at 50mm and 150mm — covering shallow and deep access with built-in off-axis flexibility, the 150mm bar providing greater reach than the 100mm bar found in many comparable compact sets
• Sliding T-bar — for high-leverage breakaway force on stubborn fixings or rapid free-spinning without a ratchet
• Universal joint — for indirect-angle fastener access in confined or obstructed spaces

The decision to include a 150mm wobble extension bar rather than a more common 100mm bar is a thoughtful specification choice for a set of this compact size. The extra 50mm of reach makes a meaningful practical difference when accessing deeply recessed fasteners inside door cavities, behind bulkheads, and within instrument panels — applications where the difference between 100mm and 150mm often determines whether a fastener can be reached without panel removal. The wobble feature at both extension lengths adds off-axis flexibility, reducing the need to substitute a universal joint for moderate angular deviations and maintaining a more rigid, controlled connection to the fastener.

The complete 25-piece set is housed in a tough blow-moulded plastic storage case in the B25MN/SG/GREEN's signature green colourway, with dedicated recesses for every socket and accessory. The green case is designed to complement Draper's colour-coded Expert range — where green is associated with the 3/8" combined MM/AF sets — but equally serves as a clear visual differentiator for any workshop using its own drive-size or set-type colour-coding system. As part of Draper's Expert range, the B25MN/SG/GREEN is manufactured and tested in general accordance with DIN3122 and ISO3315 specifications — quality verified to the standards of daily professional use.

What sockets are included in the Draper Expert B25MN/SG/GREEN? The B25MN/SG/GREEN includes 12 standard six-point metric sockets (4–13mm, including 4.5mm and 5.5mm) and 7 deep metric sockets (5, 6, 7, 8, 10, 11, 13mm) — 19 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 B25MN/SG/GREEN include a 150mm extension bar rather than 100mm? The 150mm wobble extension bar provides significantly greater reach than the 100mm bars found in many comparable compact sets — accessing deeply recessed fasteners inside door cavities, behind bulkheads, and within instrument panels that a 100mm bar cannot comfortably reach. In practice, the difference between 100mm and 150mm of reach often determines whether a fastener can be accessed without partial panel removal. For a compact 25-piece set, the 150mm bar represents a meaningful capability upgrade over shorter alternatives.

What is the difference between the Draper Expert B25MN/SG/GREEN and the B30MN/SG? The B30MN/SG offers a more comprehensive socket selection — 13 standard sockets (including 14mm) and 10 deep sockets (vs 7 in the B25MN/SG/GREEN) — plus three wobble extension bars (50mm, 100mm, and 150mm) instead of two. The B25MN/SG/GREEN is the more compact option, suited to professionals who need a capable but portable secondary set, or those whose work doesn't regularly require the 14mm size or the full three-bar extension range. The green colour-coded case also makes the B25MN/SG/GREEN a practical choice for workshops using colour identification systems.

Why does the B25MN/SG/GREEN come in a green storage case? The green colourway is part of Draper's colour-coding system for the Expert range, allowing quick visual identification of the set on a tool trolley or workshop bench. In any environment where multiple socket sets of different drive sizes or standards are stored together, colour-coded cases significantly reduce the time spent locating the right kit at the start of a job. Green also aligns with other green-cased sets in the Draper Expert range, supporting a consistent colour-coding approach across a full toolkit build-out.

What does the spinner handle in the B25MN/SG/GREEN do? The spinner handle attaches to the 1/4" square drive and allows fasteners to be rapidly spun in or out using finger rotation rather than ratcheting. Once a fastener has been broken free or started, the spinner runs it the remaining distance far more quickly than a ratchet, with significantly less hand fatigue — particularly useful for repetitive tasks involving multiple similar fixings. Its inclusion in a compact 25-piece set reflects the Expert range's professional orientation.

What is a micro satin chrome finish? Micro satin chrome is a fine, low-lustre surface treatment applied to chrome vanadium steel tools after hardening and tempering. Unlike high-polish chrome, it produces minimal glare under workshop and inspection lighting — reducing reflective eye strain during extended use. It also fingerprints less readily and maintains a cleaner, more professional appearance through daily use. The micro satin finish is the signature surface treatment of Draper's Expert range, visually and practically distinguishing it from the standard product line.

Is the Draper Expert B25MN/SG/GREEN suitable for professional automotive use? Yes. Despite its compact 25-piece size, the B25MN/SG/GREEN is built to Expert-range standards — chrome vanadium steel with micro satin chrome finish, DIN3122 and ISO3315 compliance, knurled socket rings, and a drive accessory package that includes a sliding T-bar, 150mm wobble extension bar, spinner handle, and universal joint. It is well suited as a primary compact 1/4" drive set for trim and interior work, or as a secondary set for technicians who carry a larger primary toolkit and need a portable, capable backup for on-vehicle and remote work.
