Combination Wrenches

A combination wrench has an open jaw at one end and a twelve-point ring of the same size at the other, so one tool both spins a fastener quickly and breaks it loose under torque. This page lists metric sizes from 6 mm to 50 mm and SAE sizes from 1/4″ to 2″ in straight, offset, ratcheting and long-pattern bodies, each with its jaw size, overall length and weight.
