FAQs
Can the Facom A.402 be used for loosening screws?
No, this tool is specifically designed for clockwise (tightening) operation only.
Does this tool come with bits?
The set includes an XFECR adaptor for 1/4 inch square drives and an adjustment key, but standard screwdriver bits must be sourced separately.
What is the weight of this tool?
The Facom A.402 weighs approximately 0.3kg.
Is this tool suitable for high-torque automotive work?
No, the range of 0.5 to 2.5 Nm is designed for low-torque, high-precision tasks, not heavy automotive assembly.
How do I maintain traceability?
The tool features an individual identification number laser-marked on the body, which matches the provided calibration certificate.
Troubleshooting
Torque setting moves during use
Ensure the adjustment mechanism is fully seated and locked according to the user manual; avoid touching the Vernier scale during operation.
Tool not engaging with fastener
Check that the correct bit or adaptor is fully inserted into the 1/4 inch hexagonal drive; ensure the bit head matches the fastener recess.
Uncertainty regarding calibration accuracy
Consult the individual calibration certificate provided with your serial number and consider professional recalibration if the tool has been used intensively for over a year.
Pros and Cons
Pros
- Extremely precise 0.1 Nm adjustment increments
- Compact and lightweight for easy handling in tight spaces
- Meets and exceeds ISO 6789 standards for professional reliability
- Includes essential accessories like the adaptor and adjustment key
Cons
- One-way operation only (clockwise tightening)
- Small torque range may not suit heavy-duty mechanical repairs

Setup, Compatibility & Care
To begin using the tool, ensure your screwdriver bit or square drive socket is securely seated in the hexagonal drive. To set the torque, use the provided adjustment key to turn the Vernier mechanism to the desired setting based on the 0.1 Nm markings. Store the tool in its provided case to maintain the integrity of the calibration. Periodically inspect the drive head for wear. As this is a calibrated precision instrument, avoid dropping the tool or using it as a prying implement, as this may affect its accuracy and void the reliability of the calibration certificate.
