304 Stainless Steel M2 Countersunk Flat Head Phillips Machine Screws — Flush-Fit Micro Fasteners for Electronics, Panels & Precision DIY

Protruding screw heads on thin panels, electronics enclosures, and precision assemblies create snag points, clearance problems, and an unfinished look. These 304 stainless steel M2 countersunk flat head Phillips machine screws eliminate that problem: the 90° tapered head sits flush with or below the surface for a clean, professional finish, while the 304 stainless construction provides reliable corrosion resistance without the weight or cost of larger fasteners.

Available in 24 lengths from 3mm (0.12”) to 60mm (2.36”) — all measured including the head — these M2 screws cover the full range of micro-fastener applications. The Phillips drive is compatible with standard PH0 precision screwdrivers. Pack sizes from 10 to 300 pieces let you order exactly what you need, from a single repair to a full production stock.

Typical applications include electronics enclosure and panel mounting where a flush surface is required, PCB and chassis assembly (M2 is a standard size for many electronics housings), precision instrument and optical equipment fastening, and replacement screws for appliances, laptops, and small devices that use M2 countersunk fasteners.

🔗 Compatibility: ISO metric thread — M2 (2mm diameter). Phillips PH0 drive. 90° countersunk head angle — compatible with standard metric countersunk holes. Requires pre-tapped M2 hole or matching M2 nut. Not self-tapping.

⚠️ Note: Length is measured including the head (total length). Ensure your material has a properly countersunk hole at 90° for a flush fit. Size format: M2 × [total length]mm (e.g., M2 × 10 = 2mm diameter, 10mm total length including head).

✅ Key Features of These 304 Stainless M2 Countersunk Phillips Machine Screws

📐Countersunk Flat Head (90°) — Tapered head sits flush with or below the surface; eliminates snag points and gives a clean finish on panels, enclosures, and precision assemblies.
🧄304 Stainless Steel — 18-8 austenitic stainless with excellent corrosion resistance; no rust, no plating to chip or flake — suitable for indoor and light outdoor use.
🔧Phillips PH0 Drive — Compatible with standard precision screwdrivers; controlled torque application for micro-scale fastening without cam-out.
📐24 Length Options — 3mm (0.12”) to 60mm (2.36”) in a single M2 diameter; covers short panel-mount screws through longer chassis and structural applications.
📦Packs of 10 to 300 — Order a small quantity for a repair or stock up with 200–300 pieces for production and workshop use; better per-unit value at higher quantities.
✅ISO Metric M2 Thread — Dimensionally consistent with M2 tapped holes, M2 nuts, and M2 threaded inserts; the standard size for many electronics and precision instrument housings.

❓ Frequently Asked Questions

How do I choose the right screw length?

For countersunk screws, length is measured including the head (total length). The screw should sit flush with or just below the surface when fully driven into a properly countersunk hole. Engaged thread length should be at least 3mm for M2 (1.5× the thread diameter). Available lengths: 3mm (0.12”) to 60mm (2.36”). When in doubt, size up.

What is a countersunk screw, and when should I use one?

A countersunk (flat head) screw has a tapered head that sits flush with or below the surface when driven into a countersunk hole. Use them when a flush, snag-free surface is required — such as panels, electronics enclosures, hinges, and brackets where a protruding head would interfere with fit, function, or appearance.

What is 304 stainless steel?

304 stainless steel (also called 18-8 or A2 stainless) is the most widely used grade of austenitic stainless. It offers excellent corrosion resistance, is non-magnetic in most conditions, and is the standard material for general-purpose stainless fasteners in electronics, appliances, and light outdoor use.

Are these screws rust-proof?

304 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, 316 (A4) stainless is generally recommended. These screws are well-suited for electronics, precision instruments, and indoor or sheltered applications.

What screwdriver do I need?

A Phillips PH0 precision screwdriver is recommended for M2. Always use a well-fitting driver — a loose or worn bit will strip the head on these small screws. A quality precision screwdriver set is strongly recommended.

Do these require a tapped hole or nut?

Yes — these are machine screws, not self-tapping. They require a pre-tapped M2 hole or a matching M2 metric nut. They will not cut their own thread into plastic or metal. If your application requires self-tapping, you will need a different screw type.

How strong are M2 304 stainless screws?

304 stainless steel typically has a tensile strength of around 500–700 MPa. M2 screws are designed for light clamping loads in electronics, panels, and precision instruments. Do not overtighten — M2 screws can shear if excessive torque is applied. For higher-load applications, consider a larger thread diameter.

What pack sizes are available?

Available in packs of 10, 30, 50, 100, 200, and 300 pieces. Larger packs offer better per-unit value for repair shops, workshops, and production use. Select your preferred quantity using the Pack Quantity option above.
