Great in tough environments the Split-Beam Click Torque Wrenches overcomes many of the problems associated with micrometer-style clock.  The Split-Beam wrench has few components, and all critical parts are welded together at assembly creating a very rugged system.  There is no need to "work in" a C series torque wrench before using it the first time and it is not necessary to adjust to the lowest torque setting after use.  Because the adjustment mechanism is not under load it is very easy to set the gage.  We carry Precision Instruments brand Torque Wrenches!
