M2.5 x 8mm Screws

(9 products)

M2.5 x 8mm screws are a popular length for single-board computer builds: Raspberry Pi cases and stacked PoE or NVMe HATs over standoffs, plus radio belt clips and some laptop bottom covers. This page collects every M2.5 x 8mm screw we sell.

For a Raspberry Pi stack, add the board thickness to the part of the standoff thread you want to engage; if the screw bottoms out in a short standoff, drop to 6 mm. Brass and nylon standoffs both take the same M2.5 thread. Measure an old screw with calipers: the thread diameter gives the M number and the length gives the second figure. On a countersunk head the length is measured overall, head included; on a flat-bottomed head it is measured from under the head to the tip.

How do I know these screws will fit my device?

Every listing states the exact metric thread, length, head type and finish. Match it against your original screw, your model's page in our model guides, or measure with the finder tool. If it's still wrong, we make it right.

Can I buy just one screw?

Yes — that's our specialty. Most sizes are sold as single screws, with 10-packs, 50-packs and 100-packs for shops and fleets. Each cart line needs to reach $4.99, so very low-priced singles are added in a small multiple.
