How to select the correct PROTO socket bit for Phillips screws?

To select the correct PROTO socket bit, match the drive size to your ratchet or driver (1/4 in for the J4738) and the tip size to the screw head (#2 Phillips is common for medium screws). The fixed insert design prevents bit slippage. For heavy-duty use, ensure the overall length (1 13/64 in) fits your access requirements.
