Hand Socket Wrenches are drop forged from steel bar. These wrenches are available in drive sizes of ¼”, 3/8”, ½”, 3/4” and 1”. These sockets are available in 6 point and 12 point openings in fractional sizes. Metric sizes available through ½” drive. They are available in Chrome and Industrial Black finish. These are special purpose wrenches designed for use in a wide range of sizes and capacities. All have square drives, and drive size is a measure of capacity. As detachable socket wrenches provide an almost endless combination of handles, attachments and sockets, it is possible to assemble a proper tool for almost any type of service within the tool’s capacity.
