Generic M3x6 pan head machine screw (DIN 7985H) stock item screw size
M3 · 6 mm long
If you are replacing a screw on Generic M3x6 pan head machine screw (DIN 7985H) stock item, the thread is M3, 6 mm long.
Where it is used: commodity fastener explicitly sold as M3 x 6mm; used generically in instrument enclosures and small-device assembly (cross-referenced against the Fisherbrand microplate clamp screw of the identical M3x6 size).
This entry is marked reported and comes from accu-components.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
- Board standoffs and enclosure bosses set the usable length: the screw should clamp the board without bottoming in the standoff.
- 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.
- The record states 6 mm. Going longer risks bottoming out or touching parts behind the hole; going shorter loses thread engagement.
- 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
- M3 (3.0mm, 0.5mm pitch) is not #6-32 UNC (~3.5mm) — they look identical and cross-thread, the single most common PC-building mistake.
- Telescope thumbscrews are sold in a wide non-metric legacy range too (1/4-20, 8-32, 10-32 on many Meade/Celestron mounts), so metric M3/M4 fitment applies mainly to newer/international accessory ecosystems (SkyWatcher, generic 1.25" accessories) and should not be assumed universal.

Questions about Generic M3x6 pan head machine screw (DIN 7985H) stock item screws
- What size screw does Generic M3x6 pan head machine screw (DIN 7985H) stock item use?
- M3 × 6 mm for commodity fastener explicitly sold as M3 x 6mm; used generically in instrument enclosures and small-device assembly (cross-referenced against the Fisherbrand microplate clamp screw of the identical M3x6 size).
- How long are the screws in Generic M3x6 pan head machine screw (DIN 7985H) stock item?
- The record gives 6 mm. Measure the original from under the head (overall for a countersunk head) to confirm before ordering.
- What is the thread pitch of an M3 screw?

- 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.
- Where can I buy replacement screws for Generic M3x6 pan head machine screw (DIN 7985H) stock item?
