Sourcing the right micro machine screw — the exact diameter, the exact length, in a rust-resistant material — from a single reliable listing is harder than it should be. These A2 stainless steel pan head Pozi and Phillips machine screws in M2, M2.5, and M3 cover 67 size combinations in one place, from M2×2mm (0.08”) up to M3×120mm (4.72”), all in corrosion-resistant 304 stainless steel.
The pan head profile provides a wide, flat bearing surface that distributes clamping force evenly across thin panels, PCB surfaces, and plastic housings without digging in. The Pozi (Pozidriv) drive delivers better torque transfer and reduced cam-out compared to standard Phillips — a meaningful advantage in tight spaces and with power tools. Standard Phillips drivers also engage these screws. Pack sizes of 10, 50, and 200 pieces let you order exactly what you need.
Typical applications include electronics enclosure and PCB mounting (M2–M2.5), laptop hinge and keyboard assembly (M2.5–M3), precision instrument housings, small appliance repair, and any fine DIY project where a rust-resistant metric machine screw in the M2–M3 range is required.

Measure the depth of the tapped hole or the thickness of the material being clamped. The screw length (excluding head) should engage at least 1.5× the thread diameter — at least 3mm for M2, 3.75mm for M2.5, and 4.5mm for M3. Available lengths: 2mm (0.08”) to 120mm (4.72”) depending on the diameter. When in doubt, size up.
Pozi (Pozidriv) has a second set of cross-shaped grooves at 45° to the main cross, providing better torque transfer and significantly reduced cam-out compared to standard Phillips. A Pozi driver is recommended for best results, especially with power tools. A standard Phillips driver will also engage these screws, but with slightly less torque efficiency.
A2 is the most common grade of austenitic stainless steel, equivalent to 304 or 18-8 stainless. It offers excellent corrosion resistance, is non-magnetic in most conditions, and is the standard material for precision fasteners in electronics, optical, and light outdoor applications.
A2 stainless steel provides strong corrosion resistance and will not rust under normal indoor conditions or light outdoor exposure. For marine, coastal, or highly corrosive environments, A4 (316) stainless is generally recommended. These screws are well-suited for electronics, instruments, and indoor or sheltered applications.
A Pozi (Pozidriv) or Phillips screwdriver is required. Use PZ0/PH0 for M2 and PZ1/PH1 for M2.5–M3. A Pozi driver is recommended for better torque transfer and reduced cam-out. Always use a well-fitting driver to avoid stripping the head on smaller sizes.
Yes — these are machine screws, not self-tapping. They require a pre-tapped M-series hole or a matching metric nut in the same thread size. They will not cut their own thread into plastic or metal.
A2 stainless steel typically has a tensile strength of around 500–700 MPa, which is generally sufficient for light-to-medium clamping loads in electronics, panels, and precision instruments. These screws are not intended for structural or high-load applications. Do not overtighten smaller sizes — M2 screws in particular can shear if excessive torque is applied.
Available in packs of 10, 50, and 200 pieces. The 200-piece pack offers the best per-unit value for workshops, repair shops, and production use. Select your preferred quantity using the Pack Size option above.
