A torque wrench is a precision tool designed to employ a specific amount of force to a fastener. Whether trimming head bolts on an automobile engine, lugs for tire and rim installation or scrutinizing fastener tolerances on high-energy gear, it's extremely important that appropriate care is used. Guidelines are generally provided noting acceptable torque ranges, so the order in which particular attachments are tightened and the amount of times a fastener has to be tightened and corrected to guarantee uniform torque program. Failure to properly torque fasteners can result in equipment damage, personal injury or worse. With good care, a high-quality torque wrench should supply precise measurements for many years. It's important to follow appropriate maintenance and use practices, such as: - Always follow the manufacturer's instructions regarding torque direction, correct pressure, torque pattern/sequence, use or non-use of lubrication on fasteners and
