Introducing the all-new Digital Torque and Angle Click Wrench from Sturtevant Richmont!

TAC digital torque and angle preset click wrenchIf you have indexing lines in your assembly, you'll want to consider the TAC wrench paired with the TCV e2 

From the moment you lay your eyes on this tool, you realize it is different. The gorgeous powder coated blue body stands out. It is easy to spot in a group of torque wrenches. 

The black radio case features a grey label signifying that is this a torque and angle wrench. It also has two LEDs on the case, closest to the handle. One LED is for the traditional OK/NOK indication, and it flashes Green/Red. The other LED is blue. 

When the parameter with which the tool is paired becomes active, the second LED flashes blue. When the batch is complete, the second LED turns solid blue, indicating that the batch is complete.

What makes the TAC digital torque and angle wrench so different?  

The TAC (digital torque and angle wrench) is really two wrenches in one. First, and foremost, it is a click wrench. When the preset torque value is achieved, the internal mechanism moves, striking the side of the flattened case. That creates a distinctive sound. The operator stops pulling when the wrench clicked, the LED flashes green and the display on the Global 400 advances the batch count and flashes green.

Note that there are two torque values shown on the Global 400 display. There is the "click" torque value, the point at which the wrench clicked. There is also the peak value. This is the point at which the operator stopped pulling. The display to the right also shows that the appropriate torque value was achieved 22 degrees of rotation after snug torque was achieved. 

But what if the operator continued to pull? What then? The image below shows exactly what happened.

In this case, the wrench clicked at 9.8 Newton Meters. But the operator continued to pull until the final torque was 17.3 Newton Meters. Both the TAC and the controller display flashed red, indicating NOK. 

The operator can now self diagnose and determine exactly what he or she did to illicit the NOK. This is both error proofing by guidance and error-proofing by behavior modification. 

The TAC is powered by a single AAA, NiMH battery. Extensive testing shows that the rechargeable NiMH batteries from Powerex, provide the longest battery life between changes. They are also the most environmentally friendly battery choice. NiMH batteries provide the most consistent power curve.

After recharge, there is a slight drop in the power curve. After that, the power curve is very stable until the very end. At that point, the power curve drops dramatically and it is time to change the battery. There is a battery condition display on the display of the Global 400 and Global 400mp torque controllers.

TAC CONNECT and SR CONNECT

If you are calibrating the TAC wrench, you will need the software and wireless radio interface to calibrate the tool. This package is sold separately. To get the calibration kit, order part number 10711. 

TAC CONNECT software facilitates communication with the tool during calibration. SR CONNECT is the wireless radio interface that allows TAC CONNECT software to talk with the tool. Prior to calibration, the wrench must be released from the controller. Since there is no physical access port on the tool, the calibration table must be loaded into the tool via the wireless radio interface. The SR CONNECT wireless interface facilitates that. 

We are producing videos on how to use the TAC CONNECT software and SR CONNECT wireless interface. They will be posted on a separate page on our website. 

Interchangeable Heads

By building the TAC digital torque and angle preset click wrench with our traditional pin & spring dovetail, you can use well over 200 interchangeable heads that maintain a common centerline. You can learn about the common centerline and our selection of well over 200 interchangeable heads for torque wrenches by visiting our web pages.

The TAC digital torque and angle click wrench is designed with the Sturtevant Richmont flattened case.

When we invented the preset click wrench back in 1945, we designed it with a flattened case. Why hasn't that changed after all these years? The answer is simple. The flattened base makes the wrench more durable and much harder to sideload.

Let's look at durability. Why does the flattened case make the Sturtevant Richmont Flattened case and ball bearings for preset click wrenchtorque wrenches more durable? In the photo to the left, you see the click mechanism supported by steel ball bearings. Those ball bearings guide the mechanism and reduce wear. That makes the wrench last significantly longer than those tools make with a tube case. 

A tube case places more stress on all the components of the internal workings of the torque wrench. Those stressors can cause more rapid wear as well as impact repeatability. Repeatability is impacted by other factors as well. 

The prescribed angle of a wrench to a fastener for the most accurate torque application is 90 degrees. Sideloading is bending a wrench away from the 90-degree mandate. That delivers inaccurate torque application. Sideloading the wrench by differing degrees ruins repeatability. The whole reason for using a torque wrench is to create accurate and repeatable torque application results. Sideloading the wrench defeats the purpose of using a torque wrench. 

Some companies put a "flex head" on their torque wrenches. That makes sideloading the wrench easier, not harder. Torque must be applied at 90 degrees to the fastener. Deviations from the 90 degree plane changes torque output. That adds a variable. The more you vary from 90 degrees, the bigger the impact on torque application. That is one of the reasons why Sturtevant Richmont will NEVER build a torque wrench with a "flex head". Torque wrenches were designed to eliminate variables, not introduce them.
