When working on heavy-duty projects like semi-truck wheels, tractors and farm machinery, oil rigs and equipment, or other large scale construction projects, having the right tools can mean the difference between finishing with confidence and worrying if something will come loose. The STEELMAN 60294 1-Inch Drive Heavy Duty 200-1000 ft-lb Adjustable Torque Wrench can help take the doubt out of whether or not your repairs will hold. Useable with any 1-inch drive socket and adjustable in increments of 5 ft-lb in a range of 200 to 1000 ft-lb this chrome plated tool will make a click that you can both hear and feel when you've reached the desired torque on the fastener. When extra leverage is needed the wrench includes a 41-inch extender to make quick work of the toughest jobs. The chrome plated shaft and head are rust and corrosion resistant and easy to wipe clean when soiled or oily. Torque measurements are laser-etched into the steel surface to make them easily readable when making adjustments and won't wear off or fade with time or use. To prevent accidental damage to the wrench when not in use, the included plastic storage case will ensure that it is safe from the knocks and bumps of storage and transportation that could cause a loss of calibration. To prove our confidence that your torque wrench is ready to go, right out of the box, each STEELMAN torque wrench comes with a certificate of calibration.
