Whether you're assembling a precision electronics enclosure, building a custom RC frame, or tackling a detailed mechanical repair, finding the exact metric machine screw in the right size and quantity shouldn't slow you down. Hobbyists, makers, and repair technicians alike know the frustration of a stripped or mismatched fastener mid-project — these nickel plated cross pan head machine screws are stocked in a wide size range so you always have the right one on hand.
Each screw features a pan head profile with a cross recess compatible with both Phillips (PH) and Pozidriv (PZ) drivers. Thread diameters span M1 through M5, with lengths ranging from 2mm (≈0.08") to 30mm (≈1.18"), available in quantities of 1, 10, or 50 pieces per order. The nickel plating finish provides a clean silver appearance and moderate corrosion resistance for indoor and light-duty use.
These metric pan head machine screws are well suited for electronics assembly and PCB mounting (M2–M3), small appliance repair and enclosure fastening (M2.5–M4), RC car and drone frame construction (M2–M4), and general mechanical assembly where a low-profile head and metric thread are required. The cross drive recess makes them easy to drive with standard workshop tools.

Generally, the screw length should equal the thickness of the material being fastened plus enough thread engagement in the receiving part — typically 1.5× to 2× the thread diameter. For example, an M3 screw threading into aluminum generally needs at least 4.5mm of thread engagement. When in doubt, choose a slightly longer screw and use a nut or washer to adjust. If you're fastening into a blind tapped hole, the thread engagement depth is your primary constraint.
These screws feature a cross pan head design compatible with both Phillips (PH) and Pozidriv (PZ) drivers. In most cases a PH1 or PH2 driver works for M1–M3 sizes, while a PZ1 or PZ2 driver provides better torque transfer and reduces cam-out on larger sizes like M4 and M5. Either driver type will engage the recess — Pozidriv is generally preferred for power tool use.
These are generally manufactured from steel with a nickel plating finish. Typical tensile strength for this class of fastener is in the range of 400–800 MPa depending on the base material grade. For load-critical structural applications, please contact us to confirm the specific material grade before ordering. For electronics mounting, PCB standoffs, and enclosure assembly, the strength is typically more than sufficient.
The nickel plating provides moderate corrosion resistance suitable for indoor and light-duty applications. For prolonged outdoor exposure, marine environments, or high-humidity conditions, a stainless steel or hot-dip galvanized fastener is generally recommended. If you need outdoor-rated metric pan head screws, contact us and we can point you to the right option.
These screws follow the ISO metric thread standard (M-series). They are compatible with standard metric hex nuts, nylon lock nuts, threaded brass inserts, and tapped holes of the corresponding size. For example, an M3 screw fits an M3 nut or an M3-threaded hole. No adapters or special tools are needed — any standard metric hardware will mate correctly.
For PCB standoffs, camera mounts, and small electronics enclosures, M1–M2.5 sizes are typically used. M3 is the most common size for Raspberry Pi, Arduino, and similar single-board computer projects — M3×6mm and M3×8mm are especially popular. M4 and M5 are generally used for heavier mechanical assemblies, motor mounts, and structural brackets. Choose the length based on your panel thickness plus the depth of the threaded hole or nut.
