Fastening, Torque & Joint Assembly worked example

Fastening Labor Cost at 110% chargeable labor capture: a worked example

This scenario runs the fastening labor cost calculation on the strong side: 110% chargeable labor capture, with every other input held at its documented default. Use it when quoting or staffing screwdriving, nut running, bolting, riveting, insert installation, torque audit, or fastening rework.

The inputs for this scenario

  • Direct fastening labor hours: 18 hr (unchanged)
  • Loaded fastening labor rate: 52 $ / hr (unchanged)
  • Chargeable labor capture: 110 % (raised for this scenario; the documented default is 100)
  • Fixed setup or support labor cost: 180 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable fastening labor cost = direct labor hours × loaded labor rate × chargeable labor capture) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,210 $ for total fastening labor cost, the number this scenario is built around.
  • At this operating point the engine returns 67.2 $ / hr for average cost per labor hour.
  • At this operating point the engine returns 1,030 $ for variable fastening labor cost.
  • At this operating point the engine returns 180 $ for fixed setup/support labor.

How this compares with the baseline

  • Against the tool's baseline example, where chargeable labor capture sits at 100% and the headline result is 1,116 $, this scenario comes in 8.39% above the baseline at 1,210 $.
  • Use it when quoting assembly build labor, validating a torque-station cycle standard, or evaluating the labor savings from reducing fastener count. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
