Oracle MICROS Universal PED kiosk mount screw size
M3 · 4 mm long
Oracle MICROS Universal PED kiosk mount takes M3 metric screws, 4 mm long.
It is listed for zebra scanner attaches to the mounting bracket with 2x M3 x 4mm Phillips flat-head screws.
Head and drive, as the source states them: flat / countersunk head and Phillips drive.
This entry is marked confirmed and comes from docs.oracle.com.
For reference, M3 is 3 mm across the threads at 0.5 mm pitch. The imperial size people confuse it with: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3.

How to check the screw before you buy
- Rack and enclosure hardware mixes metric and imperial (#8-32, #10-32, #6-32), so confirm the thread before forcing a screw.
- 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: the source describes a countersunk (flat) head, and those are measured overall, from the top of the head to the tip.
- The record states 4 mm. Going longer risks bottoming out or touching parts behind the hole; going shorter loses thread engagement.
- Driver: the source names a Phillips drive. For comparison, standard M3 heads take PH1 (Phillips) or T10 (Torx), or a 2.5 mm hex key.
- 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
- Eurorack rail thread varies by manufacturer: some tapped M2.5, some M3 — not a single universal standard.
- 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.

Questions about Oracle MICROS Universal PED kiosk mount screws
- What size screw does Oracle MICROS Universal PED kiosk mount use?
- M3 × 4 mm for zebra scanner attaches to the mounting bracket with 2x M3 x 4mm Phillips flat-head screws.
- How long are the screws in Oracle MICROS Universal PED kiosk mount?
- The record gives 4 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?
- 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 Oracle MICROS Universal PED kiosk mount?
- The source lists a Phillips drive. Standard M3 heads otherwise take PH1 (Phillips) or T10 (Torx), or 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.
- Where can I buy replacement screws for Oracle MICROS Universal PED kiosk mount?
- TechSpareWarehouse (our own store) lists M3 x 4mm, which matches the length in the records above.
