MacBook Air 13-inch 2017 (A1466) logic board / I/O board screw screw size
M1.6 · 3.3 mm long
The screws used on MacBook Air 13-inch 2017 (A1466) logic board / I/O board screw are M1.6, 3.3 mm long.
The record covers apple official screw chart lists part 922-9656 as 'Screw, Torx T5, M1.6 x 3.3, H3.2' for logic board and I/O board.
Head and drive, as the source states them: Torx T5 drive.
This entry is marked confirmed and comes from macrecycling.com.
An M1.6 screw is 1.6 mm in diameter with a 0.35 mm pitch, tapped with a 1.25 mm drill; imperial look-alike: #1-72 UNF (1.85 mm) is larger; there is no true imperial equivalent.

How to check the screw before you buy
- Laptop covers and brackets often mix two or three lengths of the same thread, so lay the screws out in the order they came out (a magnetic mat or a sheet of paper with the hole pattern drawn on it works).
- Diameter: across the threads an M1.6 screw measures about 1.6 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.35 mm from one thread crest to the next (28.57 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
- Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
- The record states 3.3 mm. Going longer risks bottoming out or touching parts behind the hole; going shorter loses thread engagement.
- Driver: the source names a Torx T5 drive. For comparison, standard M1.6 heads take PH00 (Phillips) or T4–T5 (Torx), or a 1.5 mm hex key.
- Tightening: no device-specific torque is published in these records. The site's general figure for M1.6 is about 12-20 N·cm into metal threads and 6-10 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M1.6
- Apple's own part naming mixes thread (M1.6) with head diameter (H3.0/H3.2) — read the full part description carefully to avoid conflating head size with thread size.

Questions about MacBook Air 13-inch 2017 (A1466) logic board / I/O board screw screws
- What size screw does MacBook Air 13-inch 2017 (A1466) logic board / I/O board screw use?
- M1.6 × 3.3 mm for apple official screw chart lists part 922-9656 as 'Screw, Torx T5, M1.6 x 3.3, H3.2' for logic board and I/O board.
- How long are the screws in MacBook Air 13-inch 2017 (A1466) logic board / I/O board screw?
- The record gives 3.3 mm. Measure the original from under the head (overall for a countersunk head) to confirm before ordering.
- What is the thread pitch of an M1.6 screw?
- 0.35 mm (coarse), which is the standard pitch for M1.6 machine screws; a 0.2 mm fine pitch exists but is uncommon. The tap drill is 1.25 mm and the normal clearance hole is 1.8 mm.
- What screwdriver do I need for MacBook Air 13-inch 2017 (A1466) logic board / I/O board screw?
- The source lists a Torx T5 drive. Standard M1.6 heads otherwise take PH00 (Phillips) or T4–T5 (Torx), or a 1.5 mm hex key.
- Can I use an imperial screw instead of M1.6?
- No. Imperial look-alike: #1-72 UNF (1.85 mm) is larger; there is no true imperial equivalent. Use a true M1.6 screw so it does not cross-thread or strip the hole.
