A wrench is a tool used to provide a advantage in applying torque to turn bolts, nuts or other hard-to-turn items. Top quality wrenches are forged from fine-grade tool steel, machined to close tolerances, hardened and tempered for long service life. The various types of wrenches include open-end wrenches, torque wrenches, box- end wrenches, combination wrenches, adjustable wrenches, socket wrenches and locking grip wrenches. Quality wrenches are designed to keep leverage and intended load in safe balance as applying excessive torque will strip or damage those threads.
