TSC MB241/MB341 industrial label printer screw size

M3 · length not stated in the sources

The screws used on TSC MB241/MB341 industrial label printer are M3. None of the sources we found gives an exact length, so measure the original before you order.

The record covers service manual specifies M3 fasteners for print engine and sensor module retention.

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

  1. 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.
  2. 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.
  3. 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.
  4. Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
  5. 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.
  6. 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

  • Grub screws (set screws) on sensor retainers are frequently M3 even when the surrounding housing uses M4/M5 fasteners — don't assume one thread size for a whole enclosure.
  • Label printer parts lists write M3*6 with an asterisk; that is still a true ISO M3 x 6mm machine screw.

Questions about TSC MB241/MB341 industrial label printer screws

What size screw does TSC MB241/MB341 industrial label printer use?
M3 for service manual specifies M3 fasteners for print engine and sensor module retention.
How long are the screws in TSC MB241/MB341 industrial label 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 MB241/MB341 industrial label 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.
