The Britool Hallmark CELM Combination Spanner Range is designed for professional mechanics, automotive technicians and engineers requiring reliable, high-quality hand tools for everyday workshop use.
Each combination spanner features a standard open-ended jaw at one end and a 12-point bi-hexagon ring at the other, providing two useful fastening options within a single professional hand tool.
Available individually in an extensive range of metric sizes from 6mm to 32mm, the CELM series provides excellent coverage for automotive servicing, mechanical repairs, engineering, machinery maintenance and general workshop applications.
Each spanner has a high-polish mirror chrome finish, providing a professional appearance while helping protect the tool against corrosion and everyday workshop wear.
Every wrench is clearly stamped with the modern Britool "The Marque of Skill" branding, together with the distinctive Hallmark stamp, individual size and identification markings.

Combination Open Jaw & Bi-Hexagon Ring Design
Each CELM spanner combines two useful profiles.
The open-ended jaw provides convenient side access to compatible nuts and bolts, making it particularly useful where there is insufficient clearance to position a ring over the fastener.
At the opposite end, the 12-point bi-hexagon ring provides enclosed fastener engagement with multiple positioning points.
The 12-point design can make repositioning easier in confined areas where the available movement around a fastener is restricted.
This combination provides a versatile professional spanner suitable for a wide variety of everyday mechanical and maintenance applications.
Professional Automotive & Engineering Applications
With sizes ranging from a compact 6mm through to 32mm, the Britool Hallmark CELM series provides extensive metric fastener coverage.
Typical applications include:
- Automotive servicing and repair
- Vehicle maintenance
- Engine and drivetrain work
- Suspension repairs
- Professional garages
- Automotive workshops
- Mechanical engineering
- Machinery servicing
- Plant maintenance
- Fleet vehicle maintenance
- General engineering
- Industrial maintenance
- Home garages and automotive enthusiasts
The broad size range makes the CELM series suitable for both smaller automotive fasteners and larger mechanical applications.
High-Polish Mirror Chrome Finish
Each Britool Hallmark CELM spanner features a high-polish mirror chrome finish.
The finish provides the professional appearance associated with quality workshop hand tools while helping protect the surface against corrosion and regular workshop conditions.
The smooth polished surface also makes the spanners easier to wipe clean following automotive and mechanical work.
Britool "The Marque of Skill" Branding
Each wrench is stamped with the modern Britool "The Marque of Skill" branding together with the famous Hallmark stamp.
Clear size and identification markings make individual spanners easier to locate within a professional toolbox and help distinguish the CELM range from other workshop tooling.
