Tri-point's Drives Detail

Tri-point

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. [70] 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.[71][72]

Tri-point-3

TP3 (sometimes referred to as tri-lobe or tri-lobular) uses a Reuleaux triangle-shaped recess in the screw head, to make it semi-secure because it cannot be driven by a flat-blade screwdriver[73] and is not readily driven, as Tri-angle is, by hex keys. It is used on fast food promotional toys and video games, die-cast toys, and some Roomba battery packs. There are four sizes: A = 2 mm, 2.3 mm, 2.7 mm, and 3.2 mm.
