Tightening Torque
Torque driver and screw tightening torque
General screws are used in this unit. Be sure to use a torque driver and tighten screws to the specified tightening torque.
Tightening Torque
M1.7 screw: 0.15 ±0.01 N·m
M2 screw: 0.20 ±0.02 N·m
M2.6 screw: 0.53 ±0.07 N·m
M3 screw: 0.80 ±0.12 N·m
Tip
• When using the torque driver with the notation of cN· m, interpret it as follows.
Example: 0.8 N· m = 80 cN· m
• Since small screws are used in the unit, they may fall into the unit when they are removed and installed. To prevent
screws from falling, it is recommended that the bit of each torque driver be magnetized to a degree that prevents
screws from falling.
