Tips on using and caring for your torque wrench

A torque wrench is a precision instrument designed to apply a specific amount of force to a fastener.  Whether tightening head bolts on an automobile engine, lugs for tire and rim installation or inspecting fastener tolerances on high-performance equipment, it is extremely important that proper care is used.  Guidelines are typically provided noting acceptable torque ranges, the order in which specific fasteners are tightened and the number of times a fastener must be tightened and loosened to ensure uniform torque application. Failure to properly torque fasteners can lead to equipment damage, personal injury or worse. With proper care, a high-quality torque wrench should provide accurate measurements for many years.
