LOW-CP Series & HTW-UT Series Hollow Hydraulic Torque Wrench Working Head and Reducer Set

Each type of LOW hollow torque wrench power has a set of working heads 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 bolts. The R and A in the following table can help you choose the right head.

LOW-CP Series	HTW-UT Series	Reducer Set

The interchangeable reducer works with the LOW series working head, allowing a single working head to match multiple bolt sizes and greatly improving adaptability to different conditions.
