Torque Tool Utilization at 92% target torque-tool utilization: a worked example

Push target torque-tool utilization up to 92% and the picture changes. This example computes every intermediate figure at that operating point. Use it when deciding whether electric screwdrivers, nutrunners, torque wrenches, or DC tools are overloaded, underused, or available for another program.

The inputs for this scenario

  • Productive torque-tool time or cycles used: 6.4 hr or cycles (unchanged)
  • Available torque-tool time or cycle capacity: 8 hr or cycles (unchanged)
  • Target torque-tool utilization: 92 % (raised for this scenario; the documented default is 80)

Working through the calculation

  • Applying the documented formula (Torque tool utilization = productive torque-tool time or cycles used รท available torque-tool capacity) to the inputs above produces each figure below.
  • At this operating point the engine returns 80 % for torque tool utilization, the number this scenario is built around.
  • At this operating point the engine returns 12 points for gap to utilization target.
  • At this operating point the engine returns 6.4 hr or cycles for used tool capacity.
  • At this operating point the engine returns 8 hr or cycles for available tool capacity.

How this compares with the baseline

  • Against the tool's baseline example, where target torque-tool utilization sits at 80% and the headline result is 80 %, this scenario lands almost exactly on the baseline at 80 %.
  • It computes utilization as productive torque-tool time or cycles divided by available capacity, then reports the gap in points between that utilization and your target. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
