PH vs JIS
-
Bits with the prefix "J" and "PH" are often thought to be the same bit. Don't be fooled by their similar appearance—they are quite different.
-
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.
-
Japanese Industrial Standard (J) screws do not provide a cam-out option, and have 90 degree corners.
