Teledyne FLIR Dragonfly S (DR-U3-50Y2) machine vision camera screw size
M2 · length not stated in the sources
If you are replacing a screw on Teledyne FLIR Dragonfly S (DR-U3-50Y2) machine vision camera, the thread is M2. None of the sources we found gives an exact length, so measure the original before you order.
The record covers cased models equipped with eight M2 x 0.4 mounting holes on top, bottom and front of case; board-level lens mount also uses M2 x 0.4 holes.
This entry is marked confirmed and comes from softwareservices.flir.com.
An M2 screw is 2 mm in diameter with a 0.4 mm pitch, tapped with a 1.6 mm drill; imperial look-alike: #2-56 UNC (2.18 mm) is close but not interchangeable.

How to check the screw before you buy
- For a wall or arm mount, the screw has to engage the threaded insert by several turns but must not bottom out, so measure the insert depth and add the thickness of the bracket and any spacers.
- Diameter: across the threads an M2 screw measures about 2 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- 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: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
- Driver: the source does not name the drive. Standard M2 heads take PH0 for Phillips and T6 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 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
- Packaging/labeling equipment manuals (e.g., cab print-and-apply applicators) mix M2 through M6 fasteners across a single machine for very different assemblies (sensors vs. frame vs. drive) — do not generalize one thread size to 'the machine' as a whole; cite the specific subassembly.
- 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.

Questions about Teledyne FLIR Dragonfly S (DR-U3-50Y2) machine vision camera screws
- What size screw does Teledyne FLIR Dragonfly S (DR-U3-50Y2) machine vision camera use?
- M2 for cased models equipped with eight M2 x 0.4 mounting holes on top, bottom and front of case; board-level lens mount also uses M2 x 0.4 holes.
- How long are the screws in Teledyne FLIR Dragonfly S (DR-U3-50Y2) machine vision camera?
- None of the sources states a length. Remove one screw and measure it from under the head to the tip (overall for a countersunk head).
- 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 Teledyne FLIR Dragonfly S (DR-U3-50Y2) machine vision camera?
- The sources do not name the drive. For M2, Phillips heads normally take PH0 and Torx heads T6; socket heads take 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.
