1/2 Inch Drive Torque Wrench

The Teng Tools 1292UAG-E4 is a 1/2 inch square drive wrench with an adjustable torque setting from 25 to 250 ft-lb. Teng Tools designs it for applying a specific torque to a fastener, such as a nut or bolt, so each one is tightened to its specified value rather than by feel.

The range of 25 to 250 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 in a pattern or a row is taken to the same number; change the setting only when the specification changes.

The 1/2 inch square drive takes standard 1/2 inch drive sockets, so the sockets already in your drawer fit without adapters. That makes it a straightforward addition to a 1/2 inch drive kit in a home garage, a service bay, a fleet workshop, a machine shop or on site.

Tightening to a set value helps prevent the two classic faults of hand tightening: a fastener left loose, and a fastener pulled past its specification. Both cost time later, so working to the number the job calls for is the simplest way to get it right the first time.

What you get: the 1292UAG-E4 adjustable wrench, 1/2 inch square drive, 25 to 250 ft-lb. Sockets are not included.

• The torque setting adjusts from 25 to 250 ft-lb, so one 1/2 inch drive wrench covers a wide span of fastening work, from smaller fasteners near the bottom of the range to larger ones near the top. Read the figure from the specification, set it on the wrench and tighten to that value instead of judging it by hand.
• The 1/2 inch square drive takes standard 1/2 inch drive sockets, so the sockets already in your toolbox drawer 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 on the bench or the tool cart.
• Teng Tools designs this wrench for applying a specific torque to a fastener such as a nut or bolt. Working to a set number rather than by feel helps stop a fastener being left loose or pulled past its specification, which matters most where a thread, a gasket or a housing gives no second chance.
• Set the figure once, then work around a bolt pattern or along a row of fasteners at that setting and change it only when the specification changes. Every fastener in the job is taken to the same number, which is the reason to tighten to a value rather than by hand.
• A 1/2 inch drive with a 25 to 250 ft-lb range suits a home garage, a service bay, a fleet workshop, a machine shop or work on site, anywhere a fastener comes with a figure in foot pounds inside that span. It is a single wrench, part number 1292UAG-E4, sold on its own rather than in a set.
