Product Information
Full details
The Facom 55A series 12 x 13mm offset ring spanner is designed for professional mechanics and automotive technicians who require precision tools for high-torque applications. Its primary benefit is the 12-sided OGV profile, which maximizes contact surface area to protect nuts and bolts from rounding, though its specialized offset design may be less effective in extremely tight spaces where a flat profile is strictly required.

FAQs
What does the OGV profile mean?
The OGV profile is a specific design that applies force to the flat sides of the nut rather than the fragile corners, significantly reducing the risk of rounding the bolt.
Is this wrench suitable for high-torque applications?
Yes, it is designed for professional use and can handle high torque, provided the tool is fully seated on the fastener.
What is the total length of the spanner?
The total length is 218 mm.
Can I use this tool with an extension bar?
It is not recommended to use 'cheater pipes' or extensions on this spanner, as it may exceed the tool's intended safety tolerances.
Is the finish chrome plated?
It features a durable satin chrome finish which provides excellent corrosion resistance.
Troubleshooting
Tool slipping on the fastener
Ensure the ring is seated fully on the fastener head and that the bolt size matches 12mm or 13mm exactly.
Surface rust appearing on the handle
Clean the surface with a fine-grade abrasive pad and apply a light coat of machine oil for protection.
Pros and Cons
Pros
- Protects fastener edges with OGV profile
- High-quality satin chrome finish for corrosion resistance
- Effective torque transmission for stubborn bolts
- Dual-size utility saves space in tool bags
Cons
- Offset design may struggle in zero-clearance environments
- Fixed dimensions limit application to 12mm and 13mm fasteners only
- Requires more lateral space than open-ended wrenches
Setup, Compatibility & Care
This spanner is ready to use out of the box and requires no calibration. It is compatible with all standard 12mm and 13mm metric fasteners. To maintain the tool's integrity, store it in a dry tool chest or hanging rack to prevent surface oxidation. After working with heavy grease or oil, wipe the tool down with a clean shop rag to ensure a secure grip for your next use. Periodically check for any deformation in the ring eyes, although the high-grade steel used in the 55A series makes this rare under normal professional conditions.
