Step 15 Coin Slot

Tightening and unscrewing the coin screw is quite effortless when using a coin as a tool because of the large size of screwhead and slot. Very similar in appearance to slot head but with a rounded concave bottom to accommodate a rounded coin shaped driver deeper. Coin screws are popular for items requiring a screw or cap that may need to be removed when no access to tools, like camping gear etc.

Here is a good example of a coin screwdriver at Promopeddler, and a coin screw cap demonstrated in a Ralph Ditton review of the SteriPen Adventurer water sterilyzer from Backpackgeartest.
