Nas Standoffs [portable] May 2026

| Thread Type | Common Use | NAS Example | |-------------|------------|--------------| | #6-32 UNC | Standard PC cases | Old Cooler Master NAS chassis | | M3 | Mini-ITX, some backplanes | Fractal Design Node 304 | | M4 | Rack rails, HDD cages | Supermicro chassis, SilverStone |

Removing standoffs stuck to a motherboard screw. Use a proper standoff driver or risk spinning the entire post.

Most NAS-specific cases (Synology, QNAP, TerraMaster) use for the mainboard and M4 for drive backplanes. Generic “PC standoff kits” often lack M4, so check your chassis manual. Ease of Installation This is where things get fiddly.

Hand-tightening works for test-fitting. Brass standoffs have shallow knurling for finger grip.

One pro tip: Thread a spare screw into the standoff before installing it into the case. This gives you leverage and prevents over-tightening. A NAS runs 24/7. Vibration from hard drives can loosen cheap standoffs over months. Loose standoffs = floating motherboard = random crashes or USB dropouts.

Worse: A missing standoff under a critical power plane can cause intermittent shorts. I’ve seen a 6-drive RAIDZ2 go poof because the builder used nylon standoffs everywhere, breaking the ground path.
