Thank you all for the discussion.
We'd never considered torque wrenches to be process equipment. They ended up under the measuring/test equipment umbrella.
To clear a few things up:
Most of the time there is no customer required torque specification. Only a handful of products we make will have a "torque to X" call out on the print. That tells me that we either need to prove all our torque wrenches are capable, or have a "Capable" set (with recrods) for production requirements and keep the others for reference only.
These torque wrenches are adjustable, I think the majority range from .2 to 25 inch/pounds. There has never been a verification across the range of the tool to determine accuracy/repeatability. This should be done to determine what shape these items are in.
When they are, for example set to 10 inch/pounds, I would check it against the torque analyzer to confirm that it actually produces that force. My understanding is that some of these wrenches will need to be cranked up to 10.5-11 in order to produce 10 inch/pounds. If that is the case, we need to invest in capable equipment.
Using the torque wrenches when there is no specific call out helps our less skilled employees understand what "acceptably tight" is, rather than stripping screws or finding "hand tightened" loose screws down the line.
Thanks for the discussion and insight. It is appreciated!
