New Tri-Wing Screwdriver Nintendo Wii GameCube DS Lite

The tri-wing screwdriver is used for screws with a 3-winged pattern on the head. These uncommon types of screws are often used by companies to prevent unwanted tampering. They are sometimes called triangular slotted screws or "tamper-resistant screws", and are difficult to find in places like retail stores.

Nintendo uses tri-wing screws in many of their video game products. You can find tri-wing screws in their Game Boy, DS, DS Lite, GameCube, and Wii products.

Apple and Sony also use tri-wing screws to secure parts of their laptops.
