When a stripped screw or a missing fastener brings your electronics repair, RC build, or precision assembly to a halt, having the right small-diameter metric screw on hand makes all the difference. These M1–M2 Phillips pan head machine screws are designed for engineers, hobbyists, repair technicians, and makers who need dependable, corrosion-resistant fasteners in miniature sizes.
Each screw is machined from 304 stainless steel and features a Phillips (cross-slot) drive pan head. Thread diameters range from M1 (1mm / ≈0.039") to M2 (2mm / ≈0.079"), with lengths available from 3mm (≈1/8") to 60mm (≈2-3/8"). Packs are available in quantities of 5, 10, 50, 100, or 200 pieces to suit both one-off repairs and bulk production needs.
These M1–M2 pan head machine screws are widely used in electronics enclosure assembly, PCB and standoff mounting, RC car and drone frames, eyeglass and optical instrument repair, and thin-panel aluminum or plastic fabrication — anywhere a small, clean-looking fastener with a flat bearing surface is required.

A general rule is to select a screw length equal to the thickness of the material being fastened plus 1–1.5× the screw diameter for thread engagement. For example, joining two 2mm plastic panels with an M2 screw typically calls for a length of 6–8mm (≈1/4"). Always confirm the available thread depth in the receiving material before ordering. For blind holes, the engaged thread length should generally be at least 1× the screw diameter.
304 stainless steel machine screws generally have a tensile strength of approximately 500–700 MPa (72,000–101,000 psi). This is typically sufficient for light-to-medium duty fastening in electronics, hobby assemblies, and precision instruments. For heavy structural or high-vibration loads, a higher-grade fastener material is generally recommended.
304 stainless steel offers good corrosion resistance in most indoor and mildly outdoor environments, resisting rust and oxidation in normal atmospheric conditions. For highly saline, marine, or chemically aggressive environments, 316 stainless steel is generally a better choice. These screws are not recommended for prolonged immersion in saltwater.
These screws follow the ISO metric thread standard. M1 has a 1mm nominal diameter with a 0.25mm pitch; M2 has a 2mm nominal diameter with a 0.4mm pitch. They are compatible with standard metric hex nuts, nylon-insert lock nuts, threaded brass inserts, and tapped holes of the corresponding size and pitch.
Driver bit size varies by screw diameter. M1–M1.2 screws typically require a PH000 bit; M1.4–M1.6 screws generally use a PH00 bit; M2 screws typically use a PH0 bit. Using the correct bit size is important to avoid cam-out and head damage on these small-diameter fasteners. A precision screwdriver set with multiple Phillips sizes is recommended.
Yes. M1–M2 Phillips pan head machine screws are commonly used in electronics enclosures, PCB standoff mounting, RC model and drone frames, eyeglass and optical instrument repair, and thin aluminum or plastic panel fabrication. In softer materials, always pre-tap the hole or use a threaded insert to ensure secure thread engagement and prevent stripping.
Each listing offers quantity options of 5, 10, 50, 100, or 200 pieces per pack. A pack of 5 or 10 is ideal for a single repair or prototype. Packs of 50–200 are more economical for production runs, workshop stocking, or repair kits where you anticipate ongoing use of a specific size.
