What is the thread pitch of an M5 screw?

0.8 mm (coarse), which is the standard pitch for M5 machine screws; a 0.5 mm fine pitch exists but is uncommon. The tap drill is 4.2 mm and the normal clearance hole is 5.5 mm.

Can I use an imperial screw instead of M5?

No. Imperial look-alike: #10-32 (4.83 mm) — the other common rack thread; check before mixing. Use a true M5 screw so it does not cross-thread or strip the hole.

Johnson Controls PENN VFD68 Variable Frequency Drive higher-power terminal block screw size

M5 · 10 mm long

If you are replacing a screw on Johnson Controls PENN VFD68 Variable Frequency Drive higher-power terminal block, the thread is M5, 10 mm long.

The record covers VFD68 terminal screw torque table explicitly lists M5 terminal screw size with associated torque for higher kW/HP rated drive terminals used to power pump and process motors.

This entry is marked confirmed and comes from docs.johnsoncontrols.com.

For reference, M5 is 5 mm across the threads at 0.8 mm pitch. The imperial size people confuse it with: #10-32 (4.83 mm) — the other common rack thread; check before mixing.

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 M5 screw measures about 5 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
Pitch: 0.8 mm from one thread crest to the next (12.5 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 10 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 M5 heads take PH2 for Phillips and T25 for Torx, and a 4 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 M5 is about 4.0-6.0 N·m into metal threads and 1.5-2.5 N·m into plastic bosses; snug it up and stop.

Common mix-ups with M5

Carbon bosses strip easily: 2-4 Nm torque and the right length so the bolt doesn't bottom out.
M5x0.8 is the de facto universal bike thread — confirm 0.8mm pitch before threading into carbon or alloy bosses.
