Precision Instruments Offers 112 standard models, covering ranges from 8 oz. in. to 75 lb. in. with a standard accuracy of 2%, there is a dial driver for any application.
As drivers are more convenient that ratchet wrenches for some applications, torque drivers are more convenient than torque wrenches for some applications. Delicate applications such as fuel injectors and fasteners used in plastics are examples of low-torque applications where tolerance is extremely tight and a torque driver is ideally suited. Also, torque drivers are not hand-hold sensitive.The largest models (50 and 75 lb. in.) feature a 1/4" female input square for attaching a T-handle or ratchet. Memory pointer models are available.
