In short, for process control.

Let’s take a look at automotive assembly plants (because that’s what I’m familiar with and where you are likely to find networked tools like this). Back in the day, torque tools on the assembly line we’re primarily air powered. Air tools are pretty great. They’re dependable and much faster than torquing fasteners by hand. They are even capable of offering limited torque control.

However, there are numerous drawbacks to using old school torque tools in an industrial setting. Under-torqued fasteners are hard to detect. You have to rely on the operator applying the appropriate number of “ugga duggas”. If an operator misses a fastener altogether, you have to hope someone downstream notices (good luck if that same operator installs a part that hides the missing fastener). Important fasteners require a second operation with a manual torque wrench to verify that the fastener is within spec, effectively doubling the labor cost for those fasteners. Plus, they are just noisy and compressed air is expensive and inefficient.

Enter electronic smart tools. These tools can be set to a specific torque window and can even detect crossed threads. Their biggest benefit is their ability to communicate with assembly line error proofing systems. These tools provide real time collection of torque data that can be transmitted wherever needed. They can be programmed to look for a preset number of good torque readings before sending a signal to the controller that allows a job to be released from the station. (The preset can be flexible to support production of different models on the same line)

For example, part of an operator’s job is to secure the front passenger seat of a car with 4 fasteners. If they fail to reach the correct torque on the first fastener, the tool will not run in forward until the fastener is backed and a retorqued to the required spec. If the operator fails to achieve 4 good torque readings before they reach the end of their work area, the assembly line will stop and an alarm will sound until the situation is corrected or error proofing is bypassed by an authorized individual.

The overwhelming majority of smart tools you will encounter on an automotive assembly line are all wired. They are mostly suspended from a rail system using retracting tool balancers. This system works fantastically most of the time, but sometimes the cable for the tool and the wire rope for the balancer make certain fasteners difficult to reach, or risk damaging paint or other sensitive surfaces. This is where Wi-Fi enabled smart tools come in.

From the supplemental agreement regarding the personal savings plan (exhibit G, available at uaw.org/gm2023)

“The Company shall increase its contribution to an Eligible Employee’s Account from 6.4% to 10% of each such Employee’s Eligible Weekly Earnings with such increase to be implemented by December 31 2023, with contributions made retroactive to October 23, 2023”

It’s a straight up contribution. For every dollar paid in wages, the company also contributes ten cents to the employees 401k. No employee contributions are required.

You’re welcome. The last part of the morse code says “remember to always drink your Ovaltine”

It was released in a limited run by Tiki Tony . The glasses came in pairs and have a COVID theme. I believe the Morse code reads “after the plague came the Renaissance,” as well as another phrase I can’t recall at the moment.

This was our third visit and I can confirm we are 3 for 3 on having a blast!
