Abstract
A hand-held power tool, in particular a screwdriver, includes a housing, in which at least one drive unit for driving a tool holder is arranged, the tool holder being designed to hold an insertion tool. The hand-held power tool further includes a torque setting device for setting a specified torque at least within specified limits. The torque setting device has a screw thread region and a spring-loaded setting unit for setting the specified torque. The setting unit is operatively connected to the screw thread region. The torque setting device is assigned a compression spring which is coaxial to the screw thread region. The compression spring is arranged such that the screw thread region surrounds the compression spring at least partly with respect to the axial direction of the drive unit.
