1/ What type of tool is the CN15LTDK-H?

The CN15LTDK-H is a preset torque screwdriver with a clutch-release mechanism, manufactured by Nakamura Mfg. Co., Ltd. (KANON). It ensures you never exceed your preset torque value.

2/ What is the adjustable torque range?

You can set torque anywhere from 1 to 15 cN·m, making it ideal for precision assembly tasks in electronics, automotive, or light-duty manufacturing.

3/ What is the smallest increment I can dial in?

The torque scale increments in 0.1 cN·m steps, so you can fine-tune your setting to match exact requirements.

4/ How accurate is the tool?

It delivers ± 3 % accuracy within the full clockwise tightening range, ensuring consistent results across multiple fastenings.

5/ How do I set and lock my desired torque?

Rotate the handle to align your target value on the external scale, then tighten the black lock ring to secure the setting and prevent unintentional changes.
