TSC MH241 industrial label printer screw size

M4 / M6 · 8 to 15 mm long

The screws used on TSC MH241 industrial label printer are M4 and M6 in lengths from 8 to 15 mm.

There are 2 separate fitment records for it, including machine screws M4*8, M4*10, M4*15 in parts list (M4) and machine screw M6*12 (M6).

2 of the 2 records are marked confirmed, drawn from 1 source (tsc-drucker.com).

An M4 screw is 4 mm in diameter with a 0.7 mm pitch, tapped with a 3.3 mm drill; imperial look-alike: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same.

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 M4 screw measures about 4 mm with calipers (usually a hair under). This device also uses M6, so measure each screw rather than assuming they match.
  3. Pitch: 0.7 mm from one thread crest to the next (14.29 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. The records span 8–15 mm, which means different positions take different lengths — match each hole to its own screw.
  6. Driver: the source does not name the drive. Standard M4 heads take PH2 for Phillips and T20 for Torx, and a 3 mm hex key for socket heads; a bit that fits loosely will cam out and strip the head.
  7. Tightening: no device-specific torque is published in these records. The site's general figure for M4 is about 2.0-3.0 N·m into metal threads and 0.8-1.4 N·m into plastic bosses; snug it up and stop.

Common mix-ups with M4 / M6

  • Water heater elements use pipe threads (NPSM/NPT), not metric machine screws.
  • Smart doorbell and lock kits bundle metric machine screws with imperial wood screws in the same bag; the metric ones are rarely labelled.

Questions about TSC MH241 industrial label printer screws

What size screw does TSC MH241 industrial label printer use?
M4 × 8–15 mm for machine screws M4*8, M4*10, M4*15 in parts list; M6 × 12 mm for machine screw M6*12.
How long are the screws in TSC MH241 industrial label printer?
The records range from 8 to 15 mm depending on the position, so match each screw to its own hole.
What is the thread pitch of an M4 screw?
0.7 mm (coarse), which is the standard pitch for M4 machine screws; a 0.5 mm fine pitch exists but is uncommon. The tap drill is 3.3 mm and the normal clearance hole is 4.5 mm.
What screwdriver do I need for TSC MH241 industrial label printer?
The sources do not name the drive. For M4, Phillips heads normally take PH2 and Torx heads T20; socket heads take a 3 mm hex key.
Can I use an imperial screw instead of M4?
No. Imperial look-alike: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same. Use a true M4 screw so it does not cross-thread or strip the hole.
