Whether you're assembling electronics enclosures, mounting PCBs, building aluminum frame structures, or repairing appliances, finding the right small-diameter metric machine screw in the exact length you need can be frustrating. These pan head Phillips machine screws are stocked in a wide range of thread sizes and lengths so you can get exactly what your project calls for — without ordering a bulk assortment you'll never use.
Each screw features a pan head profile with a Phillips (cross-head) drive recess, manufactured from carbon steel with a nickel plating finish. Thread diameters span M1.4, M1.7, M2, M2.5, M3, M4, and M5, with lengths ranging from 3mm (≈1/8") to 30mm (≈1-3/16"). Packing options of 10, 20, 50, or 100 pieces let you order the right quantity for prototyping, repair, or production runs.
These pan head Phillips machine screws are a go-to choice for electronics enclosure assembly, RC hobby builds, 3D printer frame hardware, and light mechanical assembly where a low-profile head and metric thread compatibility are required. The nickel plating adds a clean appearance and light corrosion resistance for indoor and controlled-environment use.

Generally, the screw length should equal the thickness of the material being fastened plus enough thread engagement in the receiving part — typically at least 1.5× the thread diameter. For example, an M3 screw fastening a 3mm (≈1/8") panel into a threaded insert would typically need at least 4.5mm of thread engagement, so a 6mm (≈1/4") or 8mm (≈5/16") total length is a common starting point. When in doubt, choose the next size up.
These screws follow the ISO metric thread standard (M-series). They are compatible with standard metric nuts, threaded inserts, and tapped holes of the corresponding size — for example, M3 screws fit M3 nuts and M3 tapped holes. They are not compatible with UNC/UNF inch-series threads.
The nickel plating provides a layer of corrosion resistance suitable for indoor and light-duty applications. For prolonged outdoor exposure, marine environments, or high-humidity conditions, stainless steel fasteners are generally recommended. If you need outdoor-rated options, contact us to confirm the best choice for your application.
These are general-purpose machine screws suited for light to medium-duty assembly tasks such as electronics enclosures, PCB mounting, and hobby builds. Clamping strength depends on the base material, thread engagement depth, and the material being fastened. For structural or high-load applications, consult an engineer or contact us to confirm specifications before ordering.
These screws use a Phillips (cross-head) drive. As a general guide: M1.4–M2 typically use a PH0 bit; M2.5–M3 typically use a PH1 bit; M4–M5 typically use a PH2 bit. Always use the correct bit size to avoid cam-out and head damage, especially on smaller sizes.
Yes. Pan head Phillips machine screws are widely used in electronics enclosures, PCB standoff assemblies, aluminum extrusion frames, and plastic housings. The pan head profile distributes clamping load over a wider area, making it well-suited for softer materials. For very thin plastics, consider using a washer to prevent pull-through.
Each listing offers packing options of 10, 20, 50, or 100 pieces. For one-off repairs or prototyping, the 10 or 20-piece packs are a practical choice. For small production runs or keeping a stock of common sizes on hand, the 50 or 100-piece packs offer a lower per-unit cost. Note that not all size combinations are available in every pack quantity.
