How to check the screw before you buy
- A screw that is even 1 mm too long in a laptop base can push into the keyboard, battery or a board trace, so match the length position by position.
- Diameter: across the threads an M1.6 screw measures about 1.6 mm with calipers (usually a hair under). This device also uses M2, so measure each screw rather than assuming they match.
- 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 records span 2–5.5 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source names a Phillips 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 / M2
- M.2 SSD mounting screws (M2 x 3mm) are frequently mislabeled generically as 'M.2 screws' which can be confused with the M2 metric thread designation — they do coincide numerically here but are conceptually distinct (M.2 = card format, M2 = thread size).
- The standard M.2 SSD screw is M2 x 3mm, but some laptops and handhelds use non-standard lengths or head shapes.

- 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 Lenovo YOGA 730-13IKB?
- The source lists a Phillips and Torx 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.
- Where can I buy replacement screws for Lenovo YOGA 730-13IKB?
