Product Information

Full details

The Facom Slim Metric Combination Spanner (28mm) is an essential tool for professional mechanics and serious DIY enthusiasts who require precision in tight, confined spaces. Its primary benefit is the 12-point OGV® profile, which maximizes torque transmission while protecting fasteners from wear. While it is engineered for high-performance use, the slim profile necessitates careful handling to avoid over-torquing during high-leverage operations on seized bolts.

Extended Product Information

FAQs

What does the 12-point OGV® profile mean?

It refers to the unique shape of the ring end that engages the flat sides of the bolt rather than the points, which increases torque capacity and protects the fastener.

Is this wrench suitable for heavy-duty industrial work?

Yes, the 40B series is engineered by Facom specifically for professional-grade mechanical and industrial applications.

Can I use the open end for breaking loose tight bolts?

The open end is designed for fast movement, but it is always recommended to use the 12-point ring end to break loose tight or seized bolts to prevent slippage.

Does the 15-degree offset help with clearance?

Yes, it creates a gap between your hand and the working surface, which is essential for safety and comfort in tight spaces.

How do I ensure the tool lasts?

Regularly wipe clean, store in a dry place, and avoid using the tool as a hammer or pry bar.

Troubleshooting

Wrench slips on the fastener

Ensure the ring head is seated fully onto the nut. If the nut is rounded, clean the area and verify you are using the correct metric size.

Corrosion marks appear on the surface

Gently polish the affected area with a fine-grade metal polish and ensure the tool is stored in a dry, low-humidity environment.

Pros and Cons

Pros

  • High torque transmission without nut rounding
  • Excellent accessibility in confined spaces
  • Professional-grade corrosion resistance
  • Reduced finger fatigue and injury risk due to offset design

Cons

  • Not suitable for extremely high-leverage extraction tasks
  • Slim profile may feel less substantial than thicker, heavy-duty patterns
  • Higher initial investment compared to standard hardware store wrenches

Setup, Compatibility & Care

This spanner is a standalone tool that does not require setup. It is compatible with all standard 28mm metric fasteners. To maintain the life and finish of the tool:

  1. Cleaning: Wipe down with a clean, dry cloth after use to remove grease and debris.
  2. Storage: Store in a dry tool chest or shadow board to prevent moisture accumulation on the chrome finish.
  3. Inspection: Periodically inspect the ring head for signs of debris buildup in the 12-point teeth, which can be removed with a soft wire brush.
  4. Chemicals: While the matt chrome is corrosion-resistant, avoid using harsh acidic cleaners that can compromise the surface plating.
