Each type of LOW hollow torque wrench power has a set of working head corresponding to it, they cover this type of power head that can provide all sizes of bolts within the torque range.
When selecting the appropriate working head for the bolt,note that the distance between the bolt and the wall is greater than the distance between the hexagonal edge of the working head and the outer edge of the working head.
Pay special attention to whether there is enough space between bolt and bolt. The R and A in the following table can help you choose the right head.
Interchangeable reducer
Interchangeable reducer cooperates with LOW series working head,so that a single working head can match multiple bolt size, which can greatly improve the adaptability of different conditions.
