Nintendo Switch Right Joy-Con Sensor Rail

If you’re opening up the Joy-Cons, you will need a Y00 screwdriver to remove the fasteners on the outside and a PH00 screwdriver to remove the fasteners on the inside. You'll also want to use opening picks or something similar to pry open the Joy-Cons.

You'll need a Y00 screwdriver to remove the screws on the back panel and either a JIS000 screwdriver or an official iFixit PH000 screwdriver to remove the screws on the top, bottom, and sides of the Switch console and in the kickstand well.

We refer to the Y-type screw as a “tri-point,” but you will commonly see it called a “tri-wing” on Amazon and elsewhere on the internet. An actual tri-wing screw has three slotted "wings" and a small triangular hole in the center. The slots are offset and do not intersect the center of the fastener.

Japanese Industrial Standard (JIS) screws do not provide a cam-out option and have 90-degree corners. Phillips (PH) screws are designed to make a Phillips screwdriver cam out if too much torque is applied. This prevents damage to screws and screwdrivers or bits.
Even though there is a difference between JIS and PH screws, an official iFixit PH000 driver should not damage a JIS000 screw because we manufacture our Phillips bits to be cross-compatible with JIS screws.
