How Can Tried and True

Be So Innovative and New?

We invented the first preset click wrench when our beam wrenches no longer fit in the nose cone


In 1946 our beam wrenches no longer fit in the nose cone of the new fighter planes.

So we invented the preset click wrench.

Interchangeable heads for torque wrenches by Sturtevant Richmont



In 1956 we patented the first interchangeable heads for torque wrenches.

You might recognize the dovetail design. 


Tethered preset click wrench SLTC
In 1998 we placed a cable on the end of the preset click wrench so it could talk with a PTV and a PLC. 

Next, we added an onboard radio so it could have fast, clear, communication with 2008 just released Global 8.


SLTC FM 2.4 GHz preset switch torque wrench
We upgraded from a 900 MHz radio frequency to 2.4 GHz. Then we converted the radio and the battery from a 6 volt to the AAA. Faster radio, longer battery life, lower cost battery. 

Since we invented the first preset click wrench more than 70 years ago, we've done a lot to that wrench so customers continue to gain new uses for this tool. 

The preset click wrench works with every one of our process monitors: from the PTV up to the about to be released Global 400mp. 

What else could we possibly do to that wrench? Yes, that wrench is old enough to retire, but that wrench isn't built that way. That wrench is engineered to keep working. 

The Internet of Things (IoT) is gathering more information about assemblies:

  • Who did the work?
  • When did they do it?
  • Was it done to specification? 

Data mining from the gathered data wants to know who the operator was and which tools were used. Some fasteners require two wrenches to bring the fastener into compliance. Error proofing at our level doesn't allow for wrenches to be left out of the equation. Our wireless error proofing systems are all about assembly success.

Whether you know them as "backup tools, holding tools, or holding wrenches, our radio equipped Holding Tool Technology wrenches are one of a kind. (Patent Applied For)

Global 400  SLTC Fm 2.4 GHz click wrench and the new holding toolTo solve the challenge of innovation and creating a holding tool for wireless error proofing we went to our tried and true preset click wrench.
