A. A high-quality torque wrench is a lasting tool that should provide several years of support, but they require some looking after. It changes based on the kind, so check out the manufacturer's directions carefully. Be careful not to drop it once in use. Keep it clean. Shop in an individual situation so other tools can not damage it. Torque wrenches must be recalibrated periodically -- after a year is suggested for a frequently used tool. Again, follow the manufacturer's advice.
