Verifone P400 PIN pad adapter plate mount screw screw size
M4 · length not stated in the sources
If you are replacing a screw on Verifone P400 PIN pad adapter plate mount screw, the thread is M4. None of the sources we found gives an exact length, so measure the original before you order.
Where it is used: two M4 screws on the adapter plate assembly.
This entry is marked confirmed and comes from onlinehelp.ncrvoyix.com.
For reference, M4 is 4 mm across the threads at 0.7 mm pitch. The imperial size people confuse it with: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same.

How to check the screw before you buy
- Printers and POS terminals often use self-tapping screws into plastic; re-use the original thread path instead of cutting a new one.
- Diameter: across the threads an M4 screw measures about 4 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- 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.
- 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 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.
- 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
- US-made pinball machines (Williams/Bally/Stern) overwhelmingly use imperial UTS threads (#6-32, #8-32, #10-32); explicit metric threads only appear on newer/import components such as Jersey Jack Pinball's Hobbit Smaug assembly (M3).
- M4 and 6-32 UNC share a nominal diameter with different pitch — a classic cross-thread in US-market kits.

- What size screw does Verifone P400 PIN pad adapter plate mount screw use?
- M4 for two M4 screws on the adapter plate assembly.
- How long are the screws in Verifone P400 PIN pad adapter plate mount screw?
- 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 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 Verifone P400 PIN pad adapter plate mount screw?
- 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.
