Torque Screwdriver

A Torque Wrench is a precision hand tool used to tighten bolts, nuts, and other fasteners to a specified torque value. Unlike a standard wrench, a torque wrench allows the applied tightening force to be controlled accurately. Once the required torque value is set, the tool indicates when the target value has been reached, typically by a click, mechanical release, digital alert, or visual signal. Torque wrenches are commonly used in machine assembly, cutting tool clamping, toolholding systems, automotive applications, mold making, and precision mechanical work. Their purpose is to prevent both over-tightening and under-tightening of fasteners. The main advantages of torque wrenches are accurate tightening force, high repeatability, protection of fasteners and components, reduced risk of loosening or over-tightening, and improved assembly reliability. For this reason, they are essential in applications where manufacturer-specified torque values must be applied precisely.
