These values were originally pulled from Agilent's calibrated torque wrench page, but it has disappeared. Additional information gathered from other online sources such as the Huber+Suhner and Radiall websites. Torque values can vary considerably between vendors. 1 lb-in = 11.30 N-cm Fairview Microwave sells calibrated torque wrenches. | ||
