What size screw does Wurth Elektronik WA-SPAIE plastic spacer stud use?

M2.5 × 5–65 mm for plastic PCB standoff stud; M3 × 5–65 mm for plastic PCB standoff stud.

How long are the screws in Wurth Elektronik WA-SPAIE plastic spacer stud?

The records range from 5 to 65 mm depending on the position, so match each screw to its own hole.

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 Wurth Elektronik WA-SPAIE plastic spacer stud?

The sources do not name the drive. For M2.5, Phillips heads normally take PH1 and Torx heads T8; socket heads take 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 Wurth Elektronik WA-SPAIE plastic spacer stud?

TechSpareWarehouse (our own store) lists M2.5 x 5mm, M2.5 x 6mm and M2.5 x 8mm, which match lengths in the records above.

M2.5 / M3 · 5 to 65 mm long

Wurth Elektronik WA-SPAIE plastic spacer stud takes M2.5 and M3 metric screws in lengths from 5 to 65 mm.

There are 2 separate fitment records for it, including plastic PCB standoff stud (M2.5) and plastic PCB standoff stud (M3).

2 of the 2 records are marked confirmed, drawn from 1 source (we-online.com spacer studs page).

For reference, M2.5 is 2.5 mm across the threads at 0.45 mm pitch. The imperial size people confuse it with: #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

Rack and enclosure hardware mixes metric and imperial (#8-32, #10-32, #6-32), so confirm the thread before forcing a screw.
Diameter: across the threads an M2.5 screw measures about 2.5 mm with calipers (usually a hair under). This device also uses M3, so measure each screw rather than assuming they match.
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: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
The records span 5–65 mm, which means different positions take different lengths — match each hole to its own screw.
Driver: the source does not name the drive. Standard M2.5 heads take PH1 for Phillips and T8 for Torx, and a 2 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 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 / M3

M2.5 pitch is 0.45mm vs M3's 0.5mm and M2's 0.4mm — forcing the wrong one strips plastic bosses instantly.
M2.5 and M3 look the same to the naked eye — you need calipers on the shank to tell them apart.
Intel's ATX and microATX specs never state a metric standoff thread; PC motherboard standoffs are usually imperial 6-32, and PC fan screws are commonly 6-32 self-tapping.
Motherboard screws must not poke past the standoff and touch traces on the back of the board.
