M2 Screws

(486 products)

An M2 screw has a 2 mm outside thread diameter and, in the standard coarse thread, a 0.4 mm pitch (the distance from one thread crest to the next). It is the size you meet most inside laptops, M.2 SSD slots, mechanical keyboards, small drones and handheld electronics. This page lists every M2 screw we stock, from 2 mm stubs for thin covers up to 8 mm for frames and stacked parts.

Reading the label is simple: "M2 x 4mm" means 2 mm diameter and 4 mm long. 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. Do not confuse M2 with M.2, which is the SSD form factor; many M.2 drives are actually held by an M2 x 3mm screw. If an M2 screw spins loose, the hole is probably M2.5; if it will not start, try M1.6.

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.

How fast is shipping?
