The present invention relates to torque application tools, such as a torque screwdriver and ratchet tools, with one or more light indicators disposed in a ring shape around the tool. The light indicators are adapted to indicate amounts of torque values and/or angle values as the tool is used to tighten or install a work piece. For example, the light indicators may flash at a first flashing rate, when about 40% of a target torque or angle value is applied; flash at a second flashing rate (greater or faster than the first flashing rate) when about 60% of the target torque or angle value is applied; and illuminate at a solid state when about 80% of the target torque or angle value is applied.

System and method for indicating torque

A holding tool for use in holding a first portion of an item, such as a hydraulic coupling, in a static position, while a torque application tool applies torque and rotates a second portion of the item. The holding tool helps reduce twisting of the first portion relative to the second portion when torque is applied. The holding tool also communicates with a controller when the tool is in use. For example, the tool communicates with the controller in response to a user applying a force to the tool in a direction of the first portion the tool is engaged with. That force releases pressure on a switch that activates a communication signal for communication to the controller. This allows the controller to monitor whether the holding tool was used in conjunction with a torque wrench to tighten the coupling; thereby providing an error reducing function.
