Product Information
Full details
The Facom A.444 Micro-Tech Production Torque Screwdriver is a precision-engineered instrument designed for professional assembly and industrial environments requiring consistent, repeatable torque application. It is ideal for technicians who prioritize accuracy and calibration standards in production lines. The primary benefit of this tool is its reliable torque consistency when set via a control bench; however, users should note that it is a non-graduated, single-torque-setting device that requires an external calibration tool to adjust, making it less suitable for tasks requiring frequent torque changes.

FAQs
Does the A.444 come with a calibration certificate?
Yes, each A.444 is supplied with its own unique calibration certificate and identification number.
Can I adjust the torque without a test bench?
No, because this is a non-graduated tool, you must use a control bench to verify the torque setting after adjustment.
Is this tool suitable for left-hand threads?
No, the Facom A.444 is specifically designed for right-hand torquing applications.
What bit size does the output accept?
The screwdriver accepts standard 1/4-inch hex bits.
Can I use a ratchet handle with this tool?
Yes, the handle is designed with a 1/4-inch drive to accommodate a ratchet handle such as the Facom A.300PA.
How often should I recalibrate the device?
Recalibration intervals depend on your specific quality management system, but it should be done after heavy use, accidental drops, or annually.
Troubleshooting
Torque feels inconsistent during use
Verify the tool on a calibration bench to ensure the internal spring has not shifted or worn out.
Bit slips frequently
Check the 1/4-inch hex output for debris and ensure the bit is properly seated and not worn.
Adjustment key does not move the setting
Ensure you are using the provided 4mm key and that it is fully inserted into the adjustment port.
Pros and Cons
Pros
- High-precision output for repeatable industrial tasks
- Durable construction suitable for intensive production use
- Individual calibration certificate included
- Ergonomic design with versatile drive options
Cons
- Requires a separate control bench for torque adjustment
- Non-graduated scale makes field adjustments difficult
- Optimized only for right-hand torquing
Setup, Compatibility & Care
To set up the A.444, insert the 4mm adjustment key into the setting mechanism and use a torque control bench to verify the breakaway point. Ensure that all 1/4-inch hex bits used are high-quality industrial grade to prevent cam-out and damage to the screwdriver's output. For care and maintenance, store the tool in a dry environment to protect the internal spring mechanism. If the tool is dropped or shows signs of wear, it must be re-calibrated on a control bench to ensure it still meets the specifications listed on its original certificate. Do not attempt to disassemble the tool, as this will void the calibration integrity.
