3/4 Inch Drive Torque Wrench

The Teng Tools 3492UAG-E is a 3/4 inch drive wrench with an adjustable torque setting from 50 to 300 ft-lb. Teng Tools specifies it for controlled tightening of fasteners to a specified torque, so large nuts and bolts are taken to the value the job calls for rather than finished by feel.

The range of 50 to 300 ft-lb is stated in foot pounds. Take the value from the specification, set it on the wrench and tighten. Set it once and every fastener on a flange or in a row is taken to the same number; change the setting only when the specification changes.

The 3/4 inch square drive takes standard 3/4 inch drive sockets, so the large sockets already in your kit fit without adapters. That makes it a straightforward addition to a 3/4 inch drive kit in a fleet workshop, a fabrication or machine shop, a maintenance department or on site.

On big fasteners, hand tightening tends to go wrong in one of two ways: a bolt left short of its figure, or a bolt pulled past it. Both cost time later, so tightening to the number on the specification is the simplest way to get a large joint right the first time.

What you get: the 3492UAG-E adjustable wrench, 3/4 inch drive, 50 to 300 ft-lb. Sockets are not included.

• The torque setting adjusts from 50 to 300 ft-lb, the span the larger nuts and bolts on a 3/4 inch drive job tend to call for. Read the figure from the specification, set it on the wrench and pull to that value, rather than judging a big fastener by how hard the handle feels at the end of the stroke.
• The 3/4 inch square drive takes standard 3/4 inch drive sockets, so the large sockets already in your kit in that drive size fit straight on. Sockets are sold separately, which keeps this a single purchase that works with the sizes you already own, whether they live in a drawer, on a cart or in a site box.
• Teng Tools specifies this wrench for controlled tightening of fasteners to a specified torque. On large fasteners the gap between too loose and over the specification is easy to miss by hand, so working to a set number is what keeps a joint where the drawing says it should be.
• Set the value once, then work around a flange or along a row of bolts at that setting and change it only when the specification changes. Every fastener in the pattern ends at the same figure, so the joint pulls down evenly instead of carrying a spread of guesses from bolt to bolt.
• A 3/4 inch drive with a 50 to 300 ft-lb range suits a fleet workshop, a fabrication or machine shop, a maintenance department or work on site, wherever large fasteners come with a figure in foot pounds. It is a single wrench, part number 3492UAG-E, sold on its own rather than in a set.
