i manufacture an engine component that really requires accurate torque for a proper installation.

we do not recommend the usage of "click-type" wrenches. we find that they are almost always out of calibration. furthermore, we find that the users of these wrenches think that the "click" is a torque limiter.

so, typically, they use these wrenches as if they are rowing for the harvard heavies. the "click"my be set to sound off at 60 ft lbs, but the moment of torque might go well beyond 100 ft lbs.

we recommend the balance beam style wrench. it arrests overtorque. it forces a more gentle impositon of torque.

we do not not recommend a "click" style wrench.
