M2 Countersunk Pozi Machine Screws – A2 Stainless Steel
These M2 countersunk Pozi machine screws are small, precise metric fasteners made from A2 (304) stainless steel to DIN 965 (now ISO 7046). The countersunk head sits flush with the surface, giving a neat finish on thin panels and small assemblies.
M2 is one of the smallest common metric sizes, so it's widely used for electronics, circuit boards (PCBs), model making, RC cars and drones, 3D printing, small hinges, cameras and instrument cases.
Buy Only What You Need
Every length is available as singles, or packs of 10, 100 or 1000, so you can buy one replacement screw or stock up for a production run.
Key Features
- M2 metric thread: 0.4mm coarse pitch, fully threaded
- Countersunk (flat) head: sits flush in countersunk holes
- Pozi drive (PZ1): better grip and less cam-out than Phillips

4mm, 5mm, 6mm, 8mm, 9mm, 10mm, 12mm, 16mm, 18mm and 25mm. Countersunk screw length is measured overall, including the head.

FAQs
What screwdriver do I need for M2 Pozi screws?
M2 countersunk Pozi screws take a PZ1 bit. Using the correct Pozi bit, rather than a Phillips, gives the best grip and stops the head being damaged.
What size hole do I need for an M2 screw?
To tap an M2 thread, use a 1.6mm tapping drill. For a clearance hole the screw passes straight through, use about 2.4mm.
How is a countersunk screw measured?
Countersunk screws are measured from the top of the head to the tip, because the whole head sits below the surface. So an M2 x 10mm screw is 10mm long overall.
Should I choose A2 or A4 stainless steel?
A2 (304) suits indoor and general outdoor use. For coastal areas, boats, swimming pools or constantly wet conditions, choose A4 (316) marine-grade stainless.
