The Wright Tool 8472 is a heavy-duty 1" drive dial torque wrench designed for high-torque applications from 400 to 2,000 ft-lbs. This precision instrument features a fixed head, non-ratcheting square drive built on a sturdy torsion beam design that delivers long-term accuracy and durability. At 122 inches long and weighing 44 pounds, this wrench handles the biggest bolting jobs in construction, heavy equipment, and industrial maintenance.
The large shock-resistant dial is protected by a metal guard and includes a memory needle that retains the highest torque value applied. Accuracy is +/-4% in both clockwise and counterclockwise directions from 20% to 100% of the scale range. The dual-scale display shows both English and metric readings. Each wrench meets or exceeds ASME B107.300 torque instrument standards and comes with its own serial number, storage box, and Certificate of Calibration traceable to N.I.S.T. Made in USA at Wright Tool's Van Wert, Ohio facility since 1914.
This torque wrench is essential for heavy equipment mechanics, millwrights, and structural ironworkers who need precise torque control on large fasteners. The five extension handles provide flexibility for different reach requirements. Industrial maintenance crews use these wrenches for turbine bolts, structural connections, and heavy machinery assembly where accuracy at high torque values is critical.
