Thor Zone Nanoq S PC case screw size
M3 · 4 to 10 mm long
The screws used on Thor Zone Nanoq S PC case are M3 in lengths from 4 to 10 mm.
There are 4 separate fitment records for it, including lightray/front-panel/power-button PCB and riser-cable mounting screws (multiple M3x5 used (M3), GPU lock countersunk screw securing GPU lock to core (M3) and riser-bracket countersunk mounting screw (M3), plus 1 more in the table below.
Head and drive, as the sources state them: flat / countersunk head.
4 of the 4 records are marked confirmed, drawn from 1 source (thor-zone.com).
M3 means a 3 mm nominal diameter with a 0.5 mm thread pitch. Imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3.

How to check the screw before you buy
- Laptop covers and brackets often mix two or three lengths of the same thread, so lay the screws out in the order they came out (a magnetic mat or a sheet of paper with the hole pattern drawn on it works).
- 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 records span 4–10 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
- Thor Zone Nanoq S case mixes metric M3 (various lengths: 4, 5, 6, 10, 13, 20mm) and imperial #6-32 UNC fasteners across the same build, so builders must sort hardware carefully rather than assuming an all-metric kit.
- Pond/aquarium equipment manuals aimed at consumers rarely specify exact thread pitch or length for internal fasteners, since these are considered non-user-serviceable; distributor-level assembly/service manuals (e.g., Maytronics internal documents) are a better source than end-user guides.

Questions about Thor Zone Nanoq S PC case screws
- What size screw does Thor Zone Nanoq S PC case use?
- M3 × 5 mm for lightray/front-panel/power-button PCB and riser-cable mounting screws (multiple M3x5 used throughout assembly); M3 × 6 mm for GPU lock countersunk screw securing GPU lock to core; M3 × 10 mm for riser-bracket countersunk mounting screw; M3 × 4 mm for GPU large-head screw securing GPU in riser cable bracket.
- How long are the screws in Thor Zone Nanoq S PC case?
- The records range from 4 to 10 mm depending on the position, so match each screw to its own hole.
- 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 Thor Zone Nanoq S PC case?
- The sources do not name the drive. For M3, Phillips heads normally take PH1 and Torx heads T10; socket heads take 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 Thor Zone Nanoq S PC case?
- TechSpareWarehouse (our own store) lists M3 x 5mm, M3 x 6mm and M3 x 10mm, which match lengths in the records above.
