Finding reliable miniature machine screws in M1.0, M1.2, M1.4, and M1.6 is harder than it should be. Whether you're assembling electronics, repairing optical equipment, building RC models, or working on precision instruments, undersized or poorly threaded fasteners cause real problems — stripped heads, loose fits, and wasted time. These A2 stainless steel countersunk Phillips machine screws are stocked specifically for precision and small-scale applications where standard M2+ screws are simply too large.
Each pack contains fully threaded metric machine screws in your chosen thread size, length, and quantity. Available in M1.0, M1.2, M1.4, and M1.6 diameters with lengths ranging from 3mm to 16mm (length includes the head, as is standard for countersunk screws). The flat countersunk head sits flush with or below the surface when installed in a properly prepared hole. Material is A2 (304) stainless steel for solid corrosion resistance. Pack quantities range from 10 to 300 pieces.
Typical applications include electronics chassis assembly, camera and optical device repair, drone and RC frame construction, watch and clock servicing, eyeglass frame repair, precision instrument fabrication, and any project requiring a very small metric flush-mount fastener. These miniature countersunk Phillips screws are a go-to for engineers, hobbyists, and repair technicians who need reliable small-format hardware.

For countersunk (flat head) screws, the listed length includes the head — this is the total length from the top of the head to the tip of the thread. This is the standard measurement convention for countersunk screws. When selecting a length, account for the full material thickness the screw will pass through, plus adequate thread engagement in the receiving part (typically 1.5× the screw diameter).
A2 stainless steel is the ISO designation for 304-grade austenitic stainless steel. It offers good corrosion resistance in most indoor and light outdoor environments, is non-magnetic in its annealed state, and is widely used in precision hardware, electronics, medical devices, and general fabrication. It is not recommended for harsh marine or highly corrosive environments — A4 (316) stainless is typically preferred for those applications.
These miniature screws use a Phillips drive. For M1.0 and M1.2, a PH000 or PH00 precision bit is typically required. For M1.4 and M1.6, a PH00 or PH0 bit is generally the correct fit. Always use a precision screwdriver set with the correct bit size — using an oversized bit on these small screws will cause cam-out and head damage. A quality precision screwdriver set is strongly recommended.
Yes — when installed in a properly countersunk hole, the flat head sits flush with or slightly below the surface. Without countersinking, the head will protrude. Use a countersink bit matched to the screw's head angle (typically 90° for metric machine screws) to prepare the hole correctly. For M1.0–M1.6 sizes, use a precision countersink bit appropriate for the head diameter.
These miniature screws are commonly used in electronics assembly (PCB mounting, enclosure fastening), camera and optical equipment repair, watches and clocks, RC models and drones, precision instruments, eyeglass frame repair, and any application requiring a very small metric fastener with a flush-mount head. They are a staple for electronics engineers, repair technicians, and precision hobbyists.
Yes. These follow the ISO metric coarse-pitch thread standard. They are compatible with standard metric nuts, threaded inserts, and tapped holes of the corresponding size (M1.0, M1.2, M1.4, or M1.6). They are not compatible with UNC/UNF (inch) threads. Always verify the thread pitch and hole diameter before ordering.
Pack quantities available are 10, 30, 50, 100, 200, and 300 pieces. Select your preferred quantity using the "Your Pack Quantity" selector. Larger packs offer better per-unit value for production or repair use. If you need quantities beyond 300, please contact us to discuss bulk pricing.
Yes. Flat head (countersunk) screws require a countersunk hole to sit flush. Without countersinking, the head will protrude above the surface. Use a countersink bit matched to the screw's head angle — typically 90° for metric machine screws. For M1.0–M1.6 sizes, use a precision countersink bit appropriate for the head diameter of the specific screw you're using.
