When you use the torque wrench screwdriver to approach the preset torque, you can see the red and green lights of the LED flashing and hear the buzzer sound reminder to prevent loosening due to not tightening or damage due to excessive tightening.
The adjustable torque screwdriver head is made of hardened chrome vanadium steel, the handle material is comfortable to hold, and the screen is not easy to break. The handle has a hole design, which can be hung on the wall and taken at any time or stored in the enclosed sturdy box for airtight storage.
Do not use a torque wrench beyond 120% of its maximum range.
