Torque-Tight™ ROI

Torque-Tight Lug Nut Indicator ROI breakdown

 

While mandated by the US DOT, a physical walkaround of a truck prior to operation is quite vague on the specifics. This has led many fleets implementing their own procedures and  requirements.

A number of fleets have had lug nut failures in the past and have since implemented a procedure that requires physically touching each lug nut to verify that it is at “minimum hand tight”. This can be a costly endeavor for a fleet that employs hourly drivers; for this example, we will examine a mid sized fleet with 500 power units and 1500 trailers.

 

Assumptions:

80% of the power units are active 5 days a week.

Drivers follow the procedure of touching each nut.

PU’s (power units)= 60 nuts, Trailers = 40 nuts

Each Driver cost the company $35/hr

 

Cost of Torque-Tight acquisition:

PU’s, 500 x 60 = 30,000 nuts

Trailers, 1500 x 40 = 60,000 nuts

90,000 total nuts/indicators @ $0.34/ea, Total Investment $30,600.00

 

Time investment:

During the Walkaround, on average each driver will spend 2 additional minutes physically touching each lug nut on a PU, and 1.5 min on a trailer.

400 x 3.5 = 23.33 hrs (1400 min) per day

23.33 x $35 = $816.55 / day

 

Payback:

$30,600 / $816.55 = 37.47 days

 

The initial investment of the Torque-Tight lug nut indicators is recouped in a short 38 days.
