power wrench
tool
Also known as: impact wrench
Quick Summary
A power wrench, also known as an impact wrench, is a tool designed for quickly tightening or loosening nuts. It is typically operated by electricity or compressed air. These wrenches deliver a rapid series of strong torques, allowing for efficient operation.12
Unlike hand-operated wrenches, which use a lever to grip and turn bolts or nuts, power wrenches are essentially small, handheld motors that rotate socket wrenches at high speeds. They are commonly found in automotive service settings due to their speed and efficiency.32
