A familiar name in the tool world, the ring spanner is a must-have for both the seasoned professional and the enthusiastic DIYer. The ring spanner is a double-sided tool with a closed ring head on one side and an open spanner on the other. This combination ensures maximum versatility. The ring side offers a 360-degree grip on bolts and nuts, which is ideal for places where you have little room to move. When using a ring spanner, it is important to always choose the right size to fit the bolt or nut you are working with. This will prevent damage to the tool and the workpiece.
