The DTC: Digital Torque and Angle Wrench

Slim profile, lightweight, accurate, robust, feature-rich, budget-friendly. This digital torque and angle wrench gives you big value at a small price. 

The Latest Innovation in Digital Torque and Angle Wrenches: The DTC and DTC CONNECT 2.1 are here!

When we released the DTC digital torque and angle wrench and the DTC CONNECT freeware, we noted that we would continue to refine and enhance the tool firmware along with the DTC CONNECT Freeware. True to our word we've done that. We've made great strides, but we aren't through enhancing the wrench and the freeware.  

If you are familiar with our line of tools, you probably know the 1250 Exacta Series digital torque and angle wrench. The 1250 Series transducer and all the functionality (except the radio capability) have been placed in our micrometer adjustable body. 

The result? The DTC digital torque and angle wrench. This tool is like no other. Agile. Slim. Heavy on features, yet lightweight in your hand. And, it is very lightweight on price. 

In line with our systems approach to error proofing, you cannot set the wrench to a torque value beyond the wrench capacity. Limiting torque value to wrench capacity is just one of the many features that are built into the DTC. 

The DTC has a black and white display and colored light bands on the side of the wrench. Those bands change yellow to green when the target values are achieved. An auditory beep and vibrating handle provide two additional modes of operator-focused error-proofing guidance. 

The DTC results log large enough for even the busiest assemblies. It currently holds 1000 torque results and results can be downloaded.  Using the mini-USB port, and DTC Connect Freeware, the results log can be uploaded to a computer in a CSV format.

DTC CONNECT can be used to set parameters in the wrench. You can change units of measure, modes of operation, degrees of fastener rotation, establish a target torque, minimum torque, maximum torque, and more.

DTC CONNECT is freeware and is included in the DTC price. We continue to develop DTC CONNECT and as advances are made, upgrades will be available, for free, via the website, providing that you have registered your tool on the DTC warranty page. We will email you when upgrades are made to DTC CONNECT. 

The DTC has five modes of measurement. You can operate in:

• Peak: Provides the reading of the highest torque value created during torque application. (No angle measurement)
• Track: Displays torque values as torque is being applied. (No angle measurement)
• T2A: Torque to Angle (for highly engineered assemblies)
• TAM: Torque and Angle Monitoring identifies changing joint conditions and quickly identifies attempts to tighten previously tightened fasteners, or a "double hit."
• Residual: Measures existing torque on previously tightened fasteners.

• Your DTC comes with a Certificate of Calibration from our ISO 17025 Accredited Lab.
• Our cal lab is accredited in both torque and angle.

DTC Battery Selection

Need a 400 ft-lb or 600 ft-lb Torque Wrench?

The DTC digital torque and angle wrench production stop at 250 ft-lbs. In trading the slimmer profile and weight reduction for greater access, we gave up some of the legendary strength and durability found in the Exacta 2 Series digital torque wrenches. 

If your torque application doesn't require a radio, but still needs a 400 ft-lb. or 600 ft-lb. wrench to get the job done, you'll want our Exacta 2 Series digital torque wrench. You may hear some people refer to the digital torque wrenches as electric torque wrenches because of the battery power. 

Why Torque and Angle?

Torque can be an adequate measurement for many applications. But some applications require greater accuracy. Those applications are best handled by measuring a combination of both torque, and angle. Angle is the degree of fastener rotation. For detailed information on why torque and angle, click here. 

The Transducer is the Heart of Any Torque Wrench

The strain gauge/transducer is the heart of any torque wrench. It should be the most expensive part of the wrench because it is the most important part of the tool.

If the measurement mechanism isn't accurate or can be influenced by other parts of the wrench, there isn't much value to that tool. 

You are using a torque wrench because you need an accurate measurement. Why not get the accuracy you need?

Shear Beam Design

The heart of the DTC is our patented shear beam strain gauge. Two strain gauges are mounted together. They measure force, not bending. While this may not sound like something significant, it is. 

The strain gauges are guided by eight (8) ball bearings that roll on a flattened case. The flattened case is the design basis for our preset and micrometer adjustable wrenches. The flattened case eliminates side loading by preventing the wrench from being bent away from the 90-degree plane with the fastener. 

The flattened case also provides the ball bearings a flat, smooth surface on which to roll. This supports the strain gauge which means it will be more accurate, more repeatable, and last significantly longer than round tube tools.

The DTC comes equipped with our pin and spring Dovetail head system. When we patented the first interchangeable heads for torque wrenches back in 1956, we used the Dovetail design. We've made some design enhancements over the last sixty-plus years, but the concept is still the best system of interchangeable heads on the market. 

Why?

First, the Dovetail is solid and provides robust support for the one-piece, cast heads. In the rare cases where we do cut and weld a head, great care is put into maintaining the common centerline to ensure accuracy, reliability, and durability. 

Why Is The Common Centerline So Important?

We have an entire page devoted to explaining the Common Centerline. See it here. 

Dovetail or Round Shank: Why It Matters

If product quality matters and you are torquing various fastener sizes, interchangeable heads can be an important part of maintaining consistent quality while controlling costs

There are two approaches to interchangeable heads on torque wrenches:

A. The Dovetail using a one-piece, cast heads

B. A round or square/rectangle shank system with cut and weld two-piece heads 

Each approach has advantages and very distinct characteristics. With one-piece heads, you get total consistency. If designed properly, all heads should carry a common centerline. At Sturtevant Richmont we operate with two common centerlines. Smaller wrenches use the 1 7/16" common centerline. Which is expressed as 36.5mm in metric. Larger wrenches (typically 300 ft-lbs and up) use the 3 7/8" common centerline. This is expressed as 98.4mm.

Changing the common centerline on the DTC wrench is as simple as pushing the up or down arrow on the wrench. Or, you can change the common centerline using DTC Connect Freeware. 

The cut and weld style of heads struggle to maintain an exact common centerline because of variances in the welding technique. They can also hide structural flaws from variances in heat treating and stress relief. One-piece heads also maintain consistent torque ratings. Torque rating with cut and weld heads tends to vary based on heat treating, stress relief, change in materials, and other factors. 

The Sturtevant Richmont DTC Digital Torque and Angle wrench is built from American parts and is made in Carol Stream, Illinois by highly capable and competent hands.
