SOFT / HARD Fastening Settings
Two types of fastening mode available subject to the workpiece.
 Coordinate the actual workpieces, screws and operating conditions and determine the fastening mode.

SOFT fastening setting
Suitable for workpieces with high fastening load such as tapping screws or fastening soft objects such as rubber.

HARD fastening setting
Suitable for workpieces with small fastening load such as threaded holes or rigid bodies such as metal.

Start of fastening
After starting the screwdriver, it rotates at the set speed.
During fastening
As it screws in, the load gradually increases and
the current value (torque) also rises.
End of fastening
When the screw is fastened completely and reaches the
set current value (tor6que), the current will be cut off.

HARD fastening setting

Start of fastening
After starting the screwdriver, it rotates at the set speed during FSTN-T (fastening timer) time.
During fastening
Fastens without load, and switches to the seating speed according to the torque set value just before seating the screw.
End of fastening
When the screw is fastened completely with the seating speed and reaches the set current value, the current will be cut off.

FSTN-T (Fastening Timer)
Can be set when “HARD” fastening setting is selected.
By increasing the rotation speed during no-load fastening time prior to seating,
the overall fastening time is reduced.
