How long are the screws in Raspberry Pi 5 cases?

The record gives 8 mm. Measure the original from under the head (overall for a countersunk head) to confirm before ordering.

What is the thread pitch of an M2.5 screw?

0.45 mm (coarse), which is the standard pitch for M2.5 machine screws; a 0.35 mm fine pitch exists but is uncommon. The tap drill is 2.05 mm and the normal clearance hole is 2.9 mm.

What screwdriver do I need for Raspberry Pi 5 cases?

The source lists a Phillips drive. Standard M2.5 heads otherwise take PH1 (Phillips) or T8 (Torx), or a 2 mm hex key.

Can I use an imperial screw instead of M2.5?

No. Imperial look-alike: #3-48 / #4-40 (2.51 / 2.84 mm) — #4-40 is the common US stand-in and it will NOT thread in. Use a true M2.5 screw so it does not cross-thread or strip the hole.

Where can I buy replacement screws for Raspberry Pi 5 cases?

TechSpareWarehouse (our own store) lists M2.5 x 8mm, which matches the length in the records above.

Raspberry Pi 5 cases screw size

M2.5 · 8 mm long

Raspberry Pi 5 cases takes M2.5 metric screws, 8 mm long.

It is listed for phillips flat-head case assembly screws sold specifically for Pi 5 cases.

Head and drive, as the source states them: flat / countersunk head and Phillips drive.

This entry is marked confirmed and comes from techsparewarehouse.com.

M2.5 means a 2.5 mm nominal diameter with a 0.45 mm thread pitch. Imperial look-alike: #3-48 / #4-40 (2.51 / 2.84 mm) — #4-40 is the common US stand-in and it will NOT thread in.

How to check the screw before you buy

If several screws hold the same part, check that they are all the same length before assuming they are.
Diameter: across the threads an M2.5 screw measures about 2.5 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
Pitch: 0.45 mm from one thread crest to the next (22.22 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 record states 8 mm. Going longer risks bottoming out or touching parts behind the hole; going shorter loses thread engagement.
Driver: the source names a Phillips drive. For comparison, standard M2.5 heads take PH1 (Phillips) or T8 (Torx), or a 2 mm hex key.
Tightening: no device-specific torque is published in these records. The site's general figure for M2.5 is about 45-70 N·cm into metal threads and 20-35 N·cm into plastic bosses; snug it up and stop.

Common mix-ups with M2.5

M2.5 and M3 look the same to the naked eye — you need calipers on the shank to tell them apart.
M2.5 pitch is 0.45mm vs M3's 0.5mm and M2's 0.4mm — forcing the wrong one strips plastic bosses instantly.
