Q 1. What sizes are included in the Draper 27778 HI-TORQ® spanner set?

A. The seven-piece set contains: 8 mm (237 mm overall length), 10 mm (295 mm), 12 mm (331 mm), 13 mm (351 mm), 14 mm (371 mm), 17 mm (412 mm), and 19 mm (423 mm).

Q 2. What does the 90-tooth ratchet mechanism mean in practice?

A. The 90-tooth ratchet mechanism provides 4° of movement per stroke. This allows the spanner to be used effectively in tight spaces where a full swing arc is not possible.

Q 3. What is the HI-TORQ® ring profile and why does it matter?

A. Both ring ends on every spanner in this set are 12-point HI-TORQ® profile. This design transfers torque to the flat faces of the fastener rather than the corners, which maximises leverage and reduces the risk of rounding or damaging the fastener under load. HI-TORQ® is a registered trademark of Draper Tools Ltd.

Q 4. What material are these spanners made from and how are they finished?

A. Each spanner is forged from chrome vanadium steel that has been hardened, tempered, fully polished, and mirror chrome plated. The chrome plating provides corrosion protection.

Q 5. Why are extra-long spanners useful in a professional workshop?

A. The extra-long shanks provide better access to fasteners in hard-to-reach locations and allow greater leverage than a standard-length spanner, making them particularly suited to demanding workshop and vehicle maintenance tasks.

Q 6. How is the Draper 27778 spanner set supplied and stored?

A. The complete seven-piece set is supplied in a Tetron wallet for organised storage and protection of the spanners.

Q 7. What warranty does this product come with?

A. Every product comes with a different guarantee and warranty. Warranty details are shown in the product's tech specs or datasheet where available.
