Eurorack synthesiser case (Intellijel 7U Performance Case Gen 2) screw size
M3 / M4 · 6 to 10 mm long
The screws used on Eurorack synthesiser case (Intellijel 7U Performance Case Gen 2) are M3 and M4 in lengths from 6 to 10 mm.
There are 2 separate fitment records for it, including standard Eurorack module mounting screws into the rails, M3 x 6 mm or 8 mm with a washer (M3) and case joiner / middle rail hardware — four M4 bolts, 8-10 mm recommended (M4).
2 of the 2 records are marked confirmed, drawn from 1 source (intellijel.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
- 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). This device also uses M4, so measure each screw rather than assuming they match.
- 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 records span 6–10 mm, which means different positions take different lengths — match each hole to its own screw.
- 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 / M4
- Eurorack is a strong known case with two competing metric standards (M2.5 for Vector rails, M3 for Schroff/DIN-style and 3U threaded rails); mixing rail types requires matching screw/nut thread.
- Eurorack cases mix M3 (most common) and M2.5 rails — check the case brand before buying in bulk.
- Most HVAC chassis hardware in US-market units is imperial; metric shows up mainly on European-made components.
- Not all telescope/finder hardware is metric — Celestron Edge/NexStar SE finder-shoe and dovetail screws are reported as 8/32 (imperial UNC), so metric M4/M5 fitments cannot be assumed across all Celestron products; must check per accessory/vintage.
