“Tri-Point (or Y-type)
The TP (or Y-type) security screw drive is similar to the Phillips screw head, but three points rather than four. These specialized screws are usually used on electronics equipment, including most Nintendo hardware, Sanyo and Kyocera cellular telephones, and Fuji digital cameras. 
“Apple uses Y-type screws to secure the battery on the 2010 and 2011 MacBook Pro, as well as an extremely small type in the Apple Watch, iPhone 7 and iPhone X.”
