Torque-Limiting Knobs

Set torque with a hex key to prevent overtightening that can damage sensitive equipment. Once you reach the set torque, the knob disengages and the head turns freely. Made of steel, these knobs have a black-oxide finish for mild rust resistance. Mount them on a threaded stud.
