We offer TNC torque wrenches with various torque values & for different hex nut sizes. The TNC has been around a long time and has been built to many standards, so always check the hex size of connectors you'll be working with before buying a tnc torque wrench. Current standards tend to specify 14mm (.551"), for which 9/16 wrenches (.562") work well. For many years 5/8 (.625") was a common hex size, & there have been other sizes too.
Most Commonly used TNC Torque Wrench: CT-TNC916-12
Calibration Certificates: We outsource our torque wrenches. Some don’t have any cal certificate (ex Huber Suhner 74Z-0-0-21, our CT-SMA8C, etc). Some come with a certificate which is dated because its been on the shelf for awhile (CT-516-8 etc). All parts are tested 100% in ISO9000 certified facilities. Should you need a current Cal Certificate, we can have this done at a local lab; $50 ea, 1 week; see product at bottom of each page to order.
