Draper Expert HI-TORQ® Metric Combination Spanner Set, 8 - 22mm 12 Piece

Premium Metric Spanners with Deep Offset Precision — Built for the Professional Workshop

For mechanics and engineers who demand the finest finish alongside uncompromising performance, the Draper Expert HI-TORQ® 12-Piece Metric Combination Spanner Set (8224/12/MM) sets the standard. Covering the most frequently used metric sizes from 8mm to 22mm, and featuring a distinctive deep offset pattern ring end, this set is engineered for professionals who work in tight spaces and won't compromise on quality.

Fully polished throughout and supplied on a wall mountable plastic rack, this is a set designed as much for the immaculate professional workshop as it is for the toughest mechanical tasks.

Forged for Strength — Polished to Perfection

Every spanner in this set is drop-forged from chrome vanadium steel, then hardened and tempered for exceptional toughness under sustained, high-torque use. A chrome plated finish delivers robust corrosion resistance, while the full polish throughout elevates the finish to a level that distinguishes professional-grade tooling from the ordinary. The result is a spanner that not only performs to the highest standard but looks the part in any workshop environment.

Deep Offset HI-TORQ® Ring End — A Step Above

Where many combination spanners offer a standard 15° ring offset, this set features Draper's deep offset pattern ring end — providing an increased crank angle that gives even greater knuckle clearance and access in confined, recessed, or awkward workspaces. Combined with Draper's HI-TORQ® ring end technology, which maximises the contact area between tool and fastener, the result is a spanner capable of transmitting greater torque with reduced risk of rounding off bolt heads and nuts.

The open end is set at 15°, ensuring the same ergonomic advantage at the open jaw — ideal for rapid adjustments and working at difficult angles without straining your wrist or hand.

A More Complete Metric Sequence

With sizes running consecutively from 8mm through to 17mm, then extending to 19mm and 22mm, this set covers a particularly thorough range of the most commonly encountered metric fastener sizes. The near-unbroken sequence from 8–17mm makes this set especially versatile for automotive, industrial, and general mechanical work where a full spread of smaller metric sizes is essential.

Wall Mountable Storage Rack — Organised for Efficiency

This 12-piece set is supplied on a wall mountable plastic storage rack, purpose-built for professional workshop use. Each spanner sits in its own dedicated slot, keeping sizes instantly visible and always to hand. Mount it at your workbench, above your toolbox, or in your van racking — and enjoy the efficiency of a permanently organised imperial toolkit that's always ready when you need it.

Manufactured to Industry Standards

Frequently Asked Questions

What makes the deep offset pattern different from a standard 15° offset? A deep offset ring end provides a greater crank angle than a standard 15° offset, giving additional clearance between your knuckles and the work surface. This makes it particularly valuable when working in recessed areas or on fasteners that are close to panels, engine casings, or other obstructions.

How does this set compare to the 14-piece metric set (8220/14/MM)? The 8224/12/MM features a deep offset pattern ring end and a full polish finish, making it the premium choice for professionals who want enhanced knuckle clearance and a higher-quality finish. It covers 8–22mm across 12 sequential sizes and is supplied on a wall mountable rack. The 8220/14/MM extends to 32mm with 14 pieces and comes in a portable Tetron wallet — a better choice when larger sizes or on-the-go portability are required.

What is chrome vanadium steel? Chrome vanadium (CrV) steel is a premium alloy widely used in professional hand tools, offering outstanding hardness, toughness, and fatigue resistance — essential properties for spanners used under repeated high-torque conditions.

What is the HI-TORQ® ring end? Draper's HI-TORQ® ring end is a registered trademark design that increases the contact surface between spanner and fastener, enabling higher torque to be applied safely while reducing the risk of the tool slipping and damaging bolt or nut heads.

Why is the full polish finish significant? A fully polished finish goes beyond standard chrome plating to produce a smooth, refined surface that is easier to clean, more resistant to dirt and grease build-up, and reflects the higher specification of the Draper Expert range. It is a hallmark of professional-grade tooling.

Is the storage rack easy to mount? Yes — the rack is designed for straightforward wall mounting in garages, workshops, and van racking systems, keeping your metric spanners visible, organised, and immediately accessible.
