The iPhone 12 Screw Set is a replacement kit consisting of all the internal and external screws needed to properly disassemble and reassemble the Apple iPhone 12 (models A2172, A2402, A2403, A2404). This kit is intended for technicians or DIY repairers who have lost, stripped, or need to replace screws during repairs like screen replacements, battery swaps, logic board servicing, or other component replacements

 

 

Key Features

 

 

Complete / Full Coverage
Includes all internal screws plus the two bottom exterior pentalobe screws (by the Lightning port).

 

• Correct Types & Sizes
  Variety of screw head styles used in iPhone 12:

  • Pentalobe (P2) for the two bottom external screws (≈ 6.75 mm long) 

  • Phillips screws for brackets, shields, connectors, etc. 

  • Y‑type / Tri‑point / Shoulder screws in certain places (e.g. speaker / sensor assemblies) 

 

• Quality Material
  Screws are made from corrosion‑resistant metal, with precise threading and correct dimensions to match the original OEM specifications. This helps avoid damage during reassembly. 

 

• Includes External Screws and Spares
  Many kits include spare screws, especially the external pentalobe screws, which are often lost during disassembly.

 

 

Usage & Installation Tips

 

 

Use the correct driver bits:

  • P2 Pentalobe for the bottom external screws. 

  • Phillips #00 for many of the internal screws. 

  • Tri‑point (Y000 / Y‑type) / shoulder screws for specific brackets & assemblies.

 

Keep screws organized by their location because they vary in length & head type. Using the wrong screw in the wrong place can damage components or impede assembly.

 

Do not re‑use screws that are stripped, bent, or damaged. External screws often require special Pentalobe bits and care.

 

Be careful with torque: over‑tightening can damage threads or crack parts; under‑tightening may lead to loose parts or poor electrical contact.

 

Work on a magnetic mat or use screw trays to avoid losing small screws.

 

If repairing parts like display or back cover, note that waterproof seals may be compromised when removing external screws. Replacement seal or adhesive may be required.
