When we built Class 3 we used tools calibrated regularly to guarantee that they're only capable of delivering the specified torque. The hardware being manufactured itself isn't tested except in the design stage to verify that the torque specification is right, and then only if it's a new application. -----Original Message----- From: Kathy Kuhlow [mailto:[log in to unmask]] Sent: Thursday, September 05, 2002 10:03 AM To: [log in to unmask] Subject: [TN] Torque Inspections I was curious how are torque requirements for hardware are being confirmed? If a particular piece of hardware has a torque requirement of 12in/lbs how would the verification of that piece of hardware be done? Do you use a torque driver at the same in/lbs or back off of the torque range or look for loose(gap only)?
