The set contains 12 combination ratchet spanners in sizes 8 to 19 mm for tightening and loosening screws and nuts. The ratchet direction is switched by a lever, and its 5° step allows working even in tight spaces with limited handle movement. The spanners are forged from chrome-vanadium steel and have a polished chrome-plated surface. The individual sizes are stored neatly side by side in a plastic holder.
