Draper Expert MM/AF Combined Socket Set, 3/8" Sq. Dr., Green (41 Piece)

The Draper Expert D41AMN/B/GREEN 41-Piece Combined MM/AF Socket Set is the definitive dual-standard toolkit for professionals who work across both metric and imperial fastening systems. Whether you're servicing modern European vehicles, maintaining American or classic cars, or working on imported machinery with mixed fastener standards, this set puts the right socket in your hand every time — without the need to reach for a second kit.

At its core, the D41AMN/B/GREEN delivers 17 standard metric sockets (6–22mm), 4 metric deep sockets, 9 imperial AF sockets (1/4"–3/4"), and 3 spark plug sockets (10, 12, 14mm) — all on a single 3/8" square drive platform. This breadth of coverage makes it one of the most versatile socket sets available at this drive size.

Every socket is precision-manufactured from chrome vanadium steel, hardened, tempered, and finished to a high-polished chrome that combines premium aesthetics with excellent corrosion resistance. The distinctive 12-point socket geometry — as opposed to the more common six-point design — allows engagement with fasteners from more rotational positions, making it easier to get on and off fixings in restricted spaces. The cross-knurl and three-groove grip design on each socket provides a positive, tactile grip for confident one-handed placement, even in oily or greasy conditions.

The D41AMN/B/GREEN's drive accessory collection is arguably its most compelling feature. Five separate drive tools give you unparalleled control over torque application and reach:

• 72-tooth reversible ratchet with soft-grip handle and quick-release button — a fine 5° arc for tight-space work
• Three wobble extension bars at 75mm, 150mm, and 250mm — for reach at any depth with off-axis flexibility
• Sliding T-bar — for high-leverage breakaway force or rapid free-spinning
• Flexible handle — for maximum angular reach into awkward positions
• Spinner handle — for fast, efficient running down of fasteners once broken free
• Universal joint — for indirect-angle fastener access

This level of drive accessory coverage goes well beyond what most combination socket sets offer, making the D41AMN/B/GREEN a genuine single-purchase solution for professional mechanics, classic vehicle restorers, plant and equipment engineers, and anyone who regularly crosses between metric and imperial fastener standards.

The entire set is presented in a sturdy colour-coded green storage case — the distinctive green colourway making it instantly identifiable on a busy tool trolley or shared workshop bench, and reducing the risk of mixing it with other drive-size sets.

Manufactured and tested in general accordance with DIN3122 and ISO3315 specifications, this set carries the quality assurance of Draper's Expert range — engineered for the rigours of daily professional use.

What does MM/AF mean on a socket set? MM stands for millimetre (metric), and AF stands for Across Flats (imperial/inch). A combined MM/AF socket set like the D41AMN/B/GREEN includes sockets sized in both metric millimetres and imperial inch fractions, making it suitable for working on vehicles and machinery that use either or both fastener standards.

What sockets are included in the Draper Expert D41AMN/B/GREEN? The set includes 17 metric sockets (6–22mm), 4 metric deep sockets (8, 10, 12, 13mm), 9 imperial AF sockets (1/4"–3/4"), and 3 spark plug sockets (10, 12, 14mm) — 33 sockets in total, plus 8 drive accessories, all on a 3/8" square drive.

What is the difference between 12-point and 6-point sockets? A 12-point socket has twice the number of internal engagement points as a six-point socket, allowing it to seat on a fastener from more rotational positions. This can be an advantage in confined spaces where you have limited ability to align your tool. Six-point sockets, however, distribute load across fewer, larger contact faces and are generally preferred for high-torque applications or working on worn fasteners, as they carry a lower risk of rounding.

Why is the D41AMN/B/GREEN storage case green? The green colour coding is a deliberate design choice to allow quick visual identification of this 3/8" combined MM/AF set among other drive-size sets on a tool trolley or workshop bench. It reduces the risk of mixing drive sizes and helps keep a shared or multi-set toolkit organised.

What is a flexible handle on a socket set? A flexible handle — sometimes called a flex handle or breaker bar with flex head — allows the drive end to pivot, giving you the ability to apply torque at a wide range of angles. It is particularly useful for accessing fasteners in very tight or awkward spaces where a standard ratchet or T-bar can't be positioned effectively.

Is the Draper Expert D41AMN/B/GREEN suitable for classic car restoration? Yes — this is one of the key use cases for a combined MM/AF socket set. Classic vehicles, especially those of American or British origin, predominantly use imperial AF fasteners, while more modern parts and replacement components are often metric. Having both standards in a single set is invaluable for restoration work.

What is the wobble extension bar range in this set? The D41AMN/B/GREEN includes wobble extension bars in three lengths: 75mm, 150mm, and 250mm. The wobble feature allows up to approximately 15° of off-axis movement at the socket end, enabling fastener access where a straight approach isn't possible.
