Pinball cabinet hardware (EU restorations) screw size
M4 · 8 to 25 mm long
If you are replacing a screw on Pinball cabinet hardware (EU restorations), the thread is M4 in lengths from 8 to 25 mm.
Where it is used: metric equivalents used when rebuilding US machines with metric stock.
This entry is marked reported and comes from pinside.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
- Industrial parts lists usually give the full callout (thread, length, head, grade); match all four, not just the thread.
- 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.
- The records span 8–25 mm, which means different positions take different lengths — match each hole to its own screw.
- 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).
- Pinball machines are historically imperial (UNC/UNF). Metric M4 shows up mainly in specific parts like cooling fans or in European rebuilds.

Questions about Pinball cabinet hardware (EU restorations) screws
- What size screw does Pinball cabinet hardware (EU restorations) use?
- M4 × 8–25 mm for metric equivalents used when rebuilding US machines with metric stock.
- How long are the screws in Pinball cabinet hardware (EU restorations)?
- The records range from 8 to 25 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 Pinball cabinet hardware (EU restorations)?
- 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.
