Abstract
The improved indicating device is constructed from a single piece of resilient material such as Delrin or Teflon and includes a bifurcated friction portion that is disposed in a groove in the wrench. The friction portion is constructed so that the tines can be deformed to pass through a narrow slot and frictionally engage sides of the groove. The indicator member also includes an upstanding portion that is engageable with the pointer of the torque wrench to move the indicator as the pointer moves relative to the torque scale. Since the indicator member is in frictional engagement with the torque wrench, the indicator remains at the maximum torque after releasing the torque from the wrench and permitting the pointer to return to zero, thereby facilitating reading the maximum torque exerted.
