Spiral / Screw

Spiral

When driving a screw, it usually has no any hints to show you how to operate it. While most of the screws are locked clockwise, there still have some screws have to be locked counterclockwise. A more severe case is that when you unlock a screw in the wrong way, the driving ditch of the screw head might collapse. Without changing the main design of screws, make users understand the operating procedure more easily.
