TSC TA200/TA300 barcode printer screw size
M3 · length not stated in the sources
If you are replacing a screw on TSC TA200/TA300 barcode printer, the thread is M3. None of the sources we found gives an exact length, so measure the original before you order.
It is listed for service manual print engine and gap sensor replacement steps specify M3 screws.
This entry is marked reported and comes from tsc-drucker.com.
An M3 screw is 3 mm in diameter with a 0.5 mm pitch, tapped with a 2.5 mm drill; imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3.

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 M3 screw measures about 3 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.5 mm from one thread crest to the next (20 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 M3 heads take PH1 for Phillips and T10 for Torx, and a 2.5 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 M3 is about 80-130 N·cm into metal threads and 35-60 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M3
- Many gas-detector and sensor manuals only give a torque spec (e.g. '0.5 N·m max') without repeating the thread size at every mention — the explicit M3 callout is usually only in the accessories/spare-parts table, not the main installation steps.
- Label printer parts lists write M3*6 with an asterisk; that is still a true ISO M3 x 6mm machine screw.

Questions about TSC TA200/TA300 barcode printer screws
- What size screw does TSC TA200/TA300 barcode printer use?
- M3 for service manual print engine and gap sensor replacement steps specify M3 screws.
- How long are the screws in TSC TA200/TA300 barcode printer?
- 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 M3 screw?
- 0.5 mm (coarse), which is the standard pitch for M3 machine screws; a 0.35 mm fine pitch exists but is uncommon. The tap drill is 2.5 mm and the normal clearance hole is 3.4 mm.
- What screwdriver do I need for TSC TA200/TA300 barcode printer?
- The sources do not name the drive. For M3, Phillips heads normally take PH1 and Torx heads T10; socket heads take a 2.5 mm hex key.
- Can I use an imperial screw instead of M3?
- No. Imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3. Use a true M3 screw so it does not cross-thread or strip the hole.
