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

Professional-Grade Imperial Spanners Built for Serious Work

Whether you're working on classic vehicles, agricultural machinery, or industrial equipment with imperial fixings, the Draper Expert HI-TORQ® 14-Piece Imperial Combination Spanner Set (8220/14/AF) delivers the strength, precision, and coverage professionals demand.

Spanning a comprehensive range from 3/8" to 1-1/4" AF, this 14-piece set covers the full spectrum of common imperial fastener sizes, making it an indispensable addition to any toolbox, workshop, or service vehicle.

Forged for Strength — Finished for Longevity

Every spanner in this set is drop-forged from chrome vanadium steel, then hardened and tempered to deliver outstanding toughness and resistance to wear under heavy-duty use. A bright chrome plating provides a durable barrier against rust and corrosion, keeping your tools looking and performing like new even in demanding workshop environments.

The HI-TORQ® Advantage

Draper's HI-TORQ® ring end technology is engineered to transmit greater torque to fasteners while reducing the risk of rounding off bolt heads and nuts. The ring end is offset at 15°, allowing the spanner to sit comfortably in confined spaces where a flat tool simply won't reach. The open jaw is also set at 15°, giving you the same ergonomic advantage at the open end — ideal for quick adjustments and working in tight, awkward angles.

Organised and Ready to Work

The full set arrives neatly stored in a Tetron divided wallet with tie cord, keeping every spanner in its own dedicated slot. The wallet protects your tools during storage and transport, and means you can grab the exact size you need at a glance — no more hunting through a drawer or toolbox.

Compliant with Industry Standards

This spanner set is manufactured generally in accordance with DIN3113 specifications, ensuring dimensional accuracy and performance that meets the expectations of trade professionals and serious DIYers alike.

Frequently Asked Questions

What does AF mean on spanners? AF stands for Across Flats — the standard measurement system used for imperial (inch-based) fasteners, widely used in American-manufactured equipment and older British vehicles.

What is chrome vanadium steel? Chrome vanadium (CrV) steel is a high-strength alloy widely used in professional hand tools. It offers excellent toughness, hardness, and resistance to fatigue, making it ideal for spanners and wrenches subject to high torque loads.

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, enabling higher torque application with less risk of slippage or damage to bolt heads.
