Framework Laptop 13 bottom cover / mainboard kit screw size
M1.6 / M2 · 1.5 to 3 mm long
If you are replacing a screw on Framework Laptop 13 bottom cover / mainboard kit, the thread is M1.6 and M2 in lengths from 1.5 to 3 mm.
There are 2 separate fitment records for it, including framework fastener kit: M1.6 T5, 1.5 mm length, 5.5 mm head, 0.6 mm thick (M1.6) and M2 x 3.0mm T5 screws, 4.5mm head, qty 4 (M2).
2 of the 2 records are marked confirmed, drawn from 1 source (frame.work).
M1.6 means a 1.6 mm nominal diameter with a 0.35 mm thread pitch. 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). 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 1.5–3 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M1.6 heads take PH00 for Phillips and T4–T5 for Torx, and a 1.5 mm hex key for socket heads; a bit that fits loosely will cam out and strip the head.
- 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
- M1.6 is the most common laptop-internal micro screw after M2 — Dell XPS keyboards specifically call out M1.6 x 1.5mm, and generic M2 substitutes strip the bracket.
- Framework 13 and 16 use five thread families (M1.2 to M2.5) with overlapping lengths; buy Framework's own fastener kit rather than generic M2 screws.
- The standard M.2 SSD screw is M2 x 3mm, but some laptops and handhelds use non-standard lengths or head shapes.

Questions about Framework Laptop 13 bottom cover / mainboard kit screws
- What size screw does Framework Laptop 13 bottom cover / mainboard kit use?
- M1.6 × 1.5 mm for framework fastener kit: M1.6 T5, 1.5 mm length, 5.5 mm head, 0.6 mm thick; M2 × 3 mm for M2 x 3.0mm T5 screws, 4.5mm head, qty 4.
- How long are the screws in Framework Laptop 13 bottom cover / mainboard kit?
- The records range from 1.5 to 3 mm depending on the position, so match each screw to its own hole.
- 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 Framework Laptop 13 bottom cover / mainboard kit?
- The sources do not name the drive. For M1.6, Phillips heads normally take PH00 and Torx heads T4–T5; socket heads take 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 Framework Laptop 13 bottom cover / mainboard kit?
