Assortment boxes are mostly sizes you will never touch. Pick the work you actually do and get the short list worth stocking, with sensible quantities.
Bottom covers, hinges, drives and boards. Lengths matter more than diameter here — a long screw in a short boss cracks the case.
| Size | Lengths | Stock | What it is for | Buy |
|---|---|---|---|---|
| M2 | 2, 3, 4, 5 mm | 50 of each | Bottom case, SSD, board brackets | Amazon/eBay |
| M2.5 | 3, 5, 6, 8 mm | 50 of each | Hinges, palm rest, keyboard frame | Amazon/eBay |
| M1.6 | 2, 3, 4 mm | 25 of each | Display bezel, small brackets, fans | Amazon/eBay |
| M1.2 / M1.4 | 1.5, 2, 2.5 mm | 20 of each | Camera, hinge covers, tiny flex brackets | Amazon/eBay |

Drivers to own
- PH00 and PH0
- T5 and T6 Torx
- 1.5 mm and 2 mm hex
- Plastic spudger and pry card
Worth adding
- Magnetic mat or an ice-cube tray to keep each stage of screws separate
- Countersunk and pan head in the same size — laptops mix both
- A few M2.5 standoffs for SSD and Wi-Fi card posts
Quantities assume hobby or small-shop volume. Always check the exact device page before a repair — the kit covers the common cases, not every model.
