Small-scale assemblies demand small-scale precision. Whether you're mounting a Raspberry Pi board, securing an RC model panel, assembling a camera enclosure, or building a compact electronics project, hunting down matching M2.5 screws and nuts separately wastes time and risks mismatched threading. A complete screw-and-nut set in the right length eliminates that friction entirely.
These M2.5 Phillips countersunk flat head machine screws come paired with matching M2.5 hex nuts — 20 sets per pack. The flat head profile (head diameter approximately 4.5 mm) sits flush with or below the surface when fully driven, keeping your assembly clean and snag-free. Available in four lengths — 4, 6, 16, and 25 mm — to cover thin panel mounting through deeper standoff applications. Material is iron (carbon steel), suited for general-purpose indoor mechanical and electronics use.
Ideal for Raspberry Pi and Arduino enclosures, RC models, camera equipment, small appliances, eyeglass frames, hobby electronics, and any precision mechanical assembly requiring a flush-fit M2.5 countersunk fastener with a matching nut.

Each pack contains 20 sets — 20 Phillips countersunk (flat head) M2.5 screws plus 20 matching M2.5 hex nuts. All four length options (M2.5×4, M2.5×6, M2.5×16, M2.5×25) are sold in 20-set packs.
These screws and nuts are made from iron (carbon steel). They are suitable for general-purpose indoor mechanical and electronics assembly applications where high corrosion resistance is not a primary requirement.
Available lengths are M2.5×4 mm, M2.5×6 mm, M2.5×16 mm, and M2.5×25 mm. All variants have a 2.5 mm thread diameter and a flat head diameter of approximately 4.5 mm. Select your preferred length from the Size option above.
These screws feature a countersunk (flat head) profile with a Phillips (cross) drive. The flat head sits flush with or below the surface when fully driven, making them ideal for applications requiring a clean, flush finish.
M2.5 countersunk screws are commonly used in small electronics, Raspberry Pi and Arduino enclosures, RC models, camera equipment, eyeglass frames, small appliances, and precision mechanical assemblies where a flush-fit M2.5 fastener is required.
Standard M2.5 screws use a coarse thread pitch of 0.45 mm (M2.5 x 0.45). This is the default metric coarse pitch for M2.5 and is compatible with standard M2.5 hex nuts, threaded inserts, and tapped holes.
Choose a length based on the total thickness of the materials being fastened. Short lengths (4–6 mm) suit thin panels and PCB mounting; longer lengths (16–25 mm) are better for thicker assemblies or standoff applications with a nut.
Yes. Each pack includes matching M2.5 hex nuts — one nut per screw, 20 nuts total per pack. No need to source nuts separately.
