Draper HI-TORQ® Metric Combination Spanner Set, 6-32mm (25 Piece)

The Most Complete Metric Spanner Set You'll Ever Need

For professionals who refuse to be caught without the right size, the Draper HI-TORQ® 25-Piece Metric Combination Spanner Set (8239/25/MM) is the definitive answer. Spanning an exceptional range from 6mm all the way to 32mm across 25 sizes — including a near-unbroken consecutive sequence from 6mm to 28mm — this is one of the most comprehensive metric combination spanner sets available, giving you total coverage for automotive, industrial, agricultural, and heavy mechanical work from a single purchase.

Built from chrome vanadium steel with a fully polished chrome plated finish, equipped with Draper's proven HI-TORQ® ring end technology, and supplied in a Tetron storage pouch, this set is ready to handle every metric fastener you're likely to encounter — from the finest small fixings to the largest heavy-duty bolts.

Unrivalled Size Coverage — From 6mm to 32mm

Most professional spanner sets top out at 19mm, 22mm, or 24mm, leaving mechanics and engineers short when larger fasteners are encountered. This 25-piece set eliminates that frustration entirely. The inclusion of larger sizes — 25, 26, 27, 28, 30, and 32mm — makes this set indispensable for work on:

• Heavy vehicle and commercial transport components
• Agricultural and construction machinery
• Industrial plant and equipment
• Suspension, steering, and drivetrain assemblies on larger vehicles
• Plumbing and pipework with larger metric fittings

At the other end of the scale, starting at 6mm ensures you're equally equipped for precision fasteners on motorcycles, small engines, and modern European vehicles. This is total metric coverage in a single set.

Chrome Vanadium Steel — Hardened, Tempered, and Built to Last

Every one of the 25 spanners is forged from chrome vanadium steel, then hardened and tempered for exceptional strength and long-term resistance to wear and fatigue under sustained high-torque use. Chrome vanadium is the benchmark material for professional-grade hand tools, and it ensures that every spanner in this set — from the 6mm to the 32mm — can handle the demands placed on it day after day in a busy workshop environment.

Fully Polished and Chrome Plated Throughout

This set goes a step beyond standard chrome plating with a fully polished finish throughout, producing a refined, mirror-quality surface that is easier to clean, more resistant to grease and contaminant build-up, and visually indicative of the higher specification of this set. The chrome plating adds a durable layer of corrosion protection, keeping your tools in excellent condition even in damp or challenging workshop environments. This is the finish you expect from tools that are meant to last a professional working lifetime.

The HI-TORQ® Advantage

Draper's HI-TORQ® ring end is offset at 15°, allowing the spanner to sit at a comfortable working angle and clear obstructions in confined or recessed spaces. The HI-TORQ® design maximises contact between the ring and the fastener, enabling greater torque to be applied safely while significantly reducing the risk of rounding off bolt heads and nut faces — a critical advantage when working on larger, heavier fasteners at the top of this set's range where torque demands are at their highest.

The open jaw is equally set at 15°, providing the same ergonomic benefit for open-end work — ensuring comfortable knuckle clearance and effective use at awkward angles across the full size range.

Supplied in a Tetron Storage Pouch

All 25 spanners are supplied in a Tetron storage pouch, with each spanner in its own dedicated slot for instant size identification and organised storage. The Tetron pouch is robust enough for daily workshop use and practical enough to roll up and take on site, to a job, or on the road — keeping your complete metric toolkit protected, organised, and always ready to deploy.

Frequently Asked Questions

Why choose a 25-piece set over a standard 14-piece metric set? A standard 14-piece metric set typically covers sizes up to 24mm or 32mm but with significant gaps in the sequence. This 25-piece set provides a near-consecutive range from 6mm to 28mm, plus 30mm and 32mm — meaning you have every size available for every application. For professionals working across a wide variety of vehicles, machinery, and equipment, the additional sizes eliminate the frustration and delay of being without the right spanner at a critical moment.

What makes a fully polished finish different from standard chrome plating? Standard chrome plating provides a protective layer over the steel. A fully polished finish means the tool has been polished to a smooth, refined surface before and after plating, producing a mirror-quality result that is easier to keep clean, more resistant to contamination build-up, and indicative of a higher manufacturing standard. It is the finish associated with premium, professional-grade hand tools.

What is the HI-TORQ® ring end? Draper's HI-TORQ® ring end is a registered trademark design that maximises the contact area between the spanner and the fastener. This allows greater torque to be applied safely while reducing the risk of the tool slipping and rounding off bolt or nut heads — particularly important when using the larger sizes in this set where high torque loads are common.

What is chrome vanadium steel? Chrome vanadium (CrV) steel is a high-strength alloy that is the industry standard material for professional hand tools. It offers excellent hardness, toughness, and fatigue resistance — properties essential for spanners used across the full 6–32mm size range under regular, high-torque conditions.

Is the Tetron pouch suitable for site and mobile use? Yes — the Tetron pouch is designed for both workshop storage and on-the-go use. Its divided slots keep each spanner organised and protected during transit, and the pouch format is compact enough to carry in a site bag, van, or toolbox with ease.

How does this set compare to the Draper Expert HI-TORQ® 14-piece metric set (8220/14/MM)? The 8220/14/MM covers 8–32mm across 14 selected sizes and carries the Draper Expert designation for heavy trade use, supplied in a Tetron divided wallet. The 8239/25/MM provides a far broader and more consecutive size range from 6–32mm across 25 pieces with a fully polished finish — making it the better choice for professionals who need total metric coverage and want to eliminate any gaps in their spanner collection.
