Draper HI-TORQ® Metric Combination Spanner Set (14 Piece)

Reliable Metric Spanner Coverage for Everyday Professional and DIY Use

When you need a dependable, well-specified metric spanner set that covers all the bases without compromise, the Draper HI-TORQ® 14-Piece Metric Combination Spanner Set (8233/14/MM) delivers exactly that. Spanning a broad range from 8mm to 24mm across 14 carefully selected sizes, this set provides comprehensive coverage for automotive, mechanical, and general maintenance tasks — at home, on site, or in the workshop.

Featuring Draper's trusted HI-TORQ® ring end technology, chrome vanadium steel construction, and a practical vinyl divided wallet, this is a set built to perform day in, day out across a wide range of metric applications.

Tough Materials, Lasting Performance

Every spanner in this set is forged from chrome vanadium steel, then hardened and tempered to deliver the strength and wear resistance demanded by regular, heavy use. A chrome plated finish provides reliable protection against rust and corrosion, ensuring your tools remain in excellent working condition even in wet or challenging environments. Chrome vanadium steel is the trusted material of choice for professional-grade hand tools worldwide, and it underpins the durability of every spanner in this set.

The HI-TORQ® Advantage

Draper's HI-TORQ® ring end is offset at 15°, allowing the spanner to clear obstructions and reach fasteners in confined or recessed spaces with ease. The HI-TORQ® design maximises contact between the tool and the fastener, enabling greater torque to be applied safely while reducing the risk of rounding off bolt heads and nuts — a key benefit when working with tight or corroded fixings.

The open jaw is equally set at 15°, providing the same ergonomic advantage for open-end work, giving your knuckles clearance from the work surface and making it far more comfortable to work at awkward angles.

A Broad and Practical Size Range

With 14 sizes running from 8mm through to 24mm — including a notably consecutive sequence from 8mm to 17mm, plus 19, 21, 22, and 24mm — this set covers an exceptionally practical spread of metric fastener sizes. Whether you're working on passenger cars, light commercial vehicles, motorcycles, garden machinery, or general fabrication, you'll find the size you need quickly and reliably.

Stored and Ready in a Vinyl Divided Wallet

The full 14-piece set is supplied in a vinyl divided wallet with tie cord, keeping every spanner individually slotted, protected, and easy to identify at a glance. The wallet is ideal for keeping your tools organised in a toolbox drawer, on a shelf, or in a site bag — and the tie cord keeps everything securely closed during transport.

Manufactured to Industry Standards

This set is produced generally in accordance with DIN3113 specifications, ensuring the dimensional accuracy and performance consistency expected from a reliable, everyday professional tool set.

Frequently Asked Questions

How does this set differ from the Draper Expert HI-TORQ® 14-piece metric set (8220/14/MM)? The 8233/14/MM is part of the Draper HI-TORQ® range and comes supplied in a vinyl divided wallet, covering 8–24mm across 14 sizes. The Expert 8220/14/MM extends to 32mm, is supplied in a Tetron divided wallet, and carries the additional quality assurance of the Draper Expert designation — making it the preferred choice for heavy trade use. The 8233/14/MM is an excellent, well-specified option for professionals and serious enthusiasts who work predominantly in the 8–24mm range.

What does DIN3113 mean? DIN3113 is a German industrial standard that specifies the dimensions, tolerances, and performance requirements for combination spanners. Tools manufactured in accordance with this standard offer assured dimensional accuracy and reliable performance across professional applications.

What is chrome vanadium steel? Chrome vanadium (CrV) steel is a high-strength alloy widely used in the manufacture of professional hand tools. It offers excellent hardness, toughness, and resistance to fatigue — properties that are essential for spanners subjected to regular high-torque use.

What is the HI-TORQ® ring end? Draper's HI-TORQ® ring end is a registered trademark design that increases the contact area between the spanner and the fastener. This enables higher torque to be applied safely while reducing the risk of slippage and damage to bolt or nut heads — particularly valuable when dealing with tight or corroded metric fixings.

Why does the size sequence skip certain sizes? The set has been curated to include the most frequently encountered metric fastener sizes across automotive and general mechanical use. The inclusion of 21mm alongside the more common 19mm and 22mm makes this set particularly useful for a wide range of nuts and bolt heads found on European and Japanese vehicles.

Is the vinyl wallet durable enough for workshop use? Yes — the vinyl divided wallet is designed to protect and organise your spanners during everyday storage and transport, making it well suited to toolbox use, site bags, and workshop shelving.
