B4 x 6: 1.40 ±0.20 N·m
K2.6 x6: 0.53 ±0.07 N·m
P2 x 6: 0.16 ±0.02 N·m
P2.6 x 5: 0.53 ±0.07 N·m
P4 x 12: 1.40 ±0.20 N·m

PSW3 x 6: 0.80 ±0.12 N·m
PSW3 x 8: 0.80 ±0.12 N·m
PSW3 x 10: 0.80 ±0.12 N·m
PSW3 x 40: 0.80 ±0.12 N·m
PSW4 x 8: 1.40 ±0.20 N·m
Hexagon screw: 0.53 ±0.05 N·m
DIN nut: 0.53 ±0.05 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.
Connector
Unlock it before pulling out a locking connector. If not so, this causes damage.
Screw
A New Truster (P2.6 x 5) screw cannot be reused. Prepare a new screw.
