Combination Spanner Set 6-32mm 25 Piece

Combination spanner set covering jaw sizes from 6mm to 32mm, built from chrome vanadium steel for reliable use across general workshop and trade tasks. Each spanner combines an open end and a ring end, giving flexibility to access fasteners in different positions without switching tools. Supplied in a roll bag that keeps the full set organised and easy to transport between jobs.

How a combination design saves time over separate open and ring spanners

A single-ended spanner set forces a switch between an open end and a ring end tool depending on how much clearance is available around a fastener, adding extra steps to a job that should be straightforward. That constant swapping slows work down, especially when working through a run of similar fasteners in tight or awkward positions. A combination spanner puts both ends on the same tool, so the right option is always in hand without reaching for a second spanner.

Key Features

  • Chrome vanadium steel construction: Provides strength and durability for repeated use across workshop and trade tasks.

  • Combination open and ring ends: Gives flexibility to access fasteners in tight spaces or with full grip, without needing a second spanner.

  • 25 piece range, 6mm to 32mm: Covers a comprehensive spread of jaw sizes for most general fastening tasks.

  • 125mm to 390mm length range: Longer spanners for larger fasteners give more leverage where it's needed.

  • Roll bag storage: Keeps the full set organised, protected and easy to transport between jobs.

  • General workshop and trade use: Suited to a wide range of fastening tasks across different trades.

Who is this for

This set is used by mechanics and fitters working across a range of fastener sizes on vehicles, plant and machinery. Maintenance engineers and fabricators use it as a comprehensive general spanner set covering most metric fastener sizes without needing to buy individual spanners. It suits any role needing reliable, versatile hand tools for everyday fastening tasks.

Typical applications

  • General maintenance and repair work on vehicles, plant and machinery.

  • Fastening and loosening nuts and bolts across a wide range of metric sizes.

  • Workshop and fabrication tasks requiring reliable hand tools.

  • Site maintenance tasks involving general mechanical fastenings.

  • Stocking a workshop or site van with a comprehensive spanner range.

How to use

Step 1: Select the correct jaw size spanner for the fastener from the roll bag.
Step 2: Use the ring end for maximum grip and torque, or the open end for quick access in tighter spaces.
Step 3: Apply steady, even pressure to turn the fastener, avoiding sudden jerking force.
Step 4: Return the spanner to its correct slot in the roll bag after use.
Step 5: Store the roll bag in a dry area to protect the spanners from corrosion.

Common mistakes

  • Using the wrong jaw size, which can round the fastener rather than gripping it securely.

  • Using a spanner as a hammer or striking tool, which it isn't designed for.

  • Applying excessive force with a cheater bar or extension, risking damage to the spanner or fastener.

  • Leaving spanners out of the roll bag, making it harder to find the right size quickly.

Safety

These spanners are designed for hand torque only and are not rated for use with impact tools or as a striking implement. Always select the correct jaw size to avoid slipping under load. Inspect spanners periodically for wear, cracking or rounding at the jaw.

Maintenance

Wipe spanners down after use to remove dirt, oil and debris. Store in the roll bag in a dry location to prevent corrosion. Inspect the jaws periodically for wear or rounding, and replace any spanner that no longer grips fasteners securely.

Frequently Asked Questions

Q: What is the jaw size range covered by this set?
A: This set covers jaw sizes from 6mm to 32mm across 25 spanners, giving a comprehensive range for most general metric fastening tasks without needing to buy individual sizes separately.

Q: Is there a standard this spanner set is manufactured to?
A: There's no specific EN standard covering combination spanner sets of this type, since it's a general hand tool rather than certified equipment. The key specifications to check are material, jaw size range and length range, which determine how well the set suits a particular task.

Q: What is this set NOT suitable for?
A: These spanners are designed for hand torque and shouldn't be used with impact tools or as a striking implement. They're sized for metric fasteners, not imperial (AF) sizes, so an imperial set is needed for that fastener type.

Q: Why choose a combination spanner over a separate open end and ring spanner?
A: A combination spanner puts both an open end and a ring end on the same tool, so the right option is always available without reaching for a second spanner. This saves time, particularly when working through a run of similar fasteners in different positions.

Q: What does chrome vanadium steel add over standard steel?
A: Chrome vanadium is a tougher, more durable alloy than standard carbon steel, giving the spanners better resistance to wear and deformation under repeated use. It's the standard material for quality hand tools built for regular trade or workshop use.

Q: How do I look after the spanners to extend their working life?
A: Wipe spanners down after use to remove dirt, oil and debris, and store them in the roll bag in a dry location to prevent corrosion. Inspect the jaws periodically for wear or rounding, and replace any spanner that no longer grips securely.

Q: What length are the spanners in this set?
A: Lengths range from 125mm on the smallest jaw sizes up to 390mm on the largest, giving more leverage on bigger fasteners where it's needed most.
