Wrench Head Style: The size of the socket available on the wrench, for connecting nuts and other components (such as adapters and extensions) that have a socket of corresponding size.
Torque: Torque refers to the force we can apply to the object we want to tighten, the greater the torque (Nm), the more suitable the tool is for larger objects.
Measurement Accuracy (±): Shows the maximum percentage deviation of the actual tightening torque from the selected value on the torque wrench. The lower the percentage (e.g. ±1% instead of ±4%), the greater the accuracy and reliability when tightening bolts and nuts.
