Lenovo ideapad 100S-11IBR screw size

Lenovo ideapad 100S-11IBR screw specifications

One row per fitment record. Head, drive are shown only where the source states them; pitch is the ISO coarse pitch for the thread.

How to check the screw before you buy

1. 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).
2. Diameter: across the threads an M1.4 screw measures about 1.4 mm with calipers (usually a hair under). This device also uses M2 / M2.5, so measure each screw rather than assuming they match.
3. Pitch: 0.3 mm from one thread crest to the next (33.33 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
4. Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
5. The records span 2.5–4 mm, which means different positions take different lengths — match each hole to its own screw.
6. Driver: the source names a Phillips drive. For comparison, standard M1.4 heads take PH000 / PH00 (Phillips) or T2–T3 (Torx), or a 1.3 mm hex key.
7. Tightening: no device-specific torque is published in these records. The site's general figure for M1.4 is about 8-12 N·cm into metal threads and 4-7 N·cm into plastic bosses; snug it up and stop.
