Glossary of Key Terms

  • Torque: Torque refers to the rotational force generated by the impact wrench. It is a measure of the wrench’s power and is typically measured in foot-pounds (ft-lb)
  • Anvil: The anvil is the square drive socket located at the end of the impact wrench. It is where the socket or attachment is inserted and allows for the transfer of torque to the fastener
  • Air Pressure: Impact wrenches can be powered by compressed air, and air pressure is the force exerted by the compressed air. It is typically measured in pounds per square inch (psi) and affects the performance of the impact wrench
  • Trigger: The trigger is the control mechanism on the impact wrench that is used to activate and control the operation. Pressing the trigger will start the rotation and impact action of the wrench
  • RPM: RPM stands for revolutions per minute and refers to the speed at which the impact wrench rotates. Higher RPM values generally indicate faster rotation and can affect the efficiency and performance of the tool
  • Impact Mechanism: The impact mechanism is the internal mechanism within the impact wrench that delivers repeated blows to generate torque. It typically consists of a hammer and anvil system that rapidly impacts to generate high torque output
  • Forward/Reverse Switch: The forward/reverse switch is a control feature found on impact wrenches that allows the user to change the direction of rotation. This is useful for both tightening and loosening fasteners
  • Socket Size: Socket size refers to the size of the square drive socket on the impact wrench. It determines the size of the socket or attachment that can be used with the wrench and must match the size of the fastener being worked on
