ATP striking wrenches
ATP uses an electro-chemical machining process for its extra-heavy-duty striking wrenches that makes it possible to produce these products in the “less stress” configuration. The “less stress” wrenches are manufactured from perfectly matched steel, making them durable and reliable. They are available in both inch and metric sizes, from 7/8 inches (22 millimeters) to 9 inches
