Precision Instruments’ Split-Beam Click Wrenches overcome many of the problems associated with micrometer-style clock wrenches in abusive environments. The wrench has few components, and all critical parts are welded together at assembly. There is no need to “work in” a C series torque wrench before using it the first time. Nor is it necessary to adjust to the lowest torque setting after use. Setting the tool requires only fingertip force since the adjustment mechanism is not under load.
