How to check the screw before you buy
- For medical and lab equipment, use the manufacturer's replacement part where one is specified; the thread size here helps identify it, not certify it.
- Diameter: across the threads an M2 screw measures about 2 mm with calipers (usually a hair under). This device also uses M4 / M5 / M6, so measure each screw rather than assuming they match.
- Pitch: 0.4 mm from one thread crest to the next (25 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
- Length: for pan head / binding head / set screw (headless) screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- The records span 5–28 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source names a Hex socket (Allen) drive. For comparison, standard M2 heads take PH0 (Phillips) or T6 (Torx), or a 1.5 mm hex key.
- Tightening: no device-specific torque is published in these records. The site's general figure for M2 is about 25-40 N·cm into metal threads and 12-20 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M2 / M4 / M5 / M6
- M2 (2.00mm, 0.4mm pitch) is NOT the same as #2-56 UNC (2.18mm) — close enough to cross-thread and strip if forced.
- M4 and 6-32 UNC share a nominal diameter with different pitch — a classic cross-thread in US-market kits.
- Ski and snowboard binding screws vary by brand and insert system (4x4, Channel, Tyrolia, Marker). Aftermarket suppliers standardise on M5/M6 but OEM screws can be a different pitch.

- How long are the screws in Takara Belmont PRO III 047 dental chair?
- The records range from 5 to 28 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M2 screw?
- 0.4 mm (coarse), which is the standard pitch for M2 machine screws; a 0.25 mm fine pitch exists but is uncommon. The tap drill is 1.6 mm and the normal clearance hole is 2.4 mm.
- What screwdriver do I need for Takara Belmont PRO III 047 dental chair?
- The source lists a Hex socket (Allen) drive. Standard M2 heads otherwise take PH0 (Phillips) or T6 (Torx), or a 1.5 mm hex key.
- Can I use an imperial screw instead of M2?
- No. Imperial look-alike: #2-56 UNC (2.18 mm) is close but not interchangeable. Use a true M2 screw so it does not cross-thread or strip the hole.
