The 32mm nut has become the standard for 7/16 connectors / 7-16 torque wrenches; we still come across some 27mm nuts, so we offer 7/16 torque wrenches for both hex sizes. While the standard torque to be applied to a 7/16 DIN connector is a hefty 221 in-lbs or higher, some manufacturers including Keysight recommend 20 in-lbs for lab tests; so we have these 7/16 DIN torque wrenches also.
Most Commonly used 7/16 Torque Wrench: CT-716-32-221
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; $60 ea, 2 weeks; see product at bottom of each page to order.
