Most people just hand-tighten their coax cables, let alone actually use a torque wrench to get the perfect torque. If you want to “do it right,” Jonard makes a series of torque wrenches designed specifically to prevent over-tightening 7/16-inch “F” connectors on Coax Cable.
When you’ve reached the specified torque with this 6-1/2″ wrench, you’ll hear an audible click. Jonard mentions that these wrenches only work in tightening mode, which isn’t that uncommon — do you use your torque wrench to loosen your lug nuts?
Jonard sells four models: a full head and a speed head in 20 inch-pound and 30 inch-pound versions. Any of ’em will run you $27 before shipping.
