iPhone Duo Screws
This section shows the screw diagrams, screws, and torque drivers for iPhone Duo.
Warning
Never reinstall a screw after it has been removed. Install only new screws. iPhone screws are covered with an adhesive that can’t be reused. Discard screws according to your local recycling guidelines.
Use only the torque driver indicated to install new screws during reassembly. Both overtightened screws and loose screws can damage parts.
Screw trays
A screw tray is included with a replacement part and includes new screws needed to complete a repair.
A screw tray uses a grid format to easily identify the correct screw needed for a repair step. For example, A1 = 923-15881 and A2 = 923-15882.
Only the screws needed to complete the repair for the replacement part ordered are included in a screw tray.
