Finding the right black machine screw across the full M1–M6 range — the exact diameter, the exact length, with a drive that won’t cam out — from a single listing is rarely straightforward. These black Pozi and Phillips pan head machine screws cover M1.0 through M6 in lengths from 2mm (0.08”) to 50mm (1.97”), with a black oxide or zinc finish for corrosion resistance and a clean, low-profile appearance in visible assemblies.
The pan head profile provides a wide, flat bearing surface that distributes clamping force evenly across panels, PCB surfaces, and plastic housings. The Pozi (Pozidriv) drive delivers better torque transfer and reduced cam-out compared to standard Phillips — a meaningful advantage in tight spaces and with power tools. Standard Phillips drivers also engage these screws. Pack sizes from 1 to 100 pieces let you order a single replacement or stock a full range.
Typical applications include eyeglass and micro electronics repair (M1.0–M1.6), laptop hinge and keyboard assembly (M2–M2.5), electronics enclosure and PCB mounting (M2–M3), PC case assembly and panel mounting (M3–M4), and general-purpose DIY and workshop projects (M4–M6) where a black finish is preferred.

Measure the depth of the tapped hole or the thickness of the material being clamped. The screw length (excluding head) should engage at least 1.5× the thread diameter. Available lengths: 2mm (0.08”) to 50mm (1.97”) depending on the diameter. Not all lengths are available for every diameter — check the variant selector. When in doubt, size up.
Pozi (Pozidriv) has a second set of cross-shaped grooves at 45° to the main cross, providing better torque transfer and significantly reduced cam-out compared to standard Phillips. A Pozi driver is recommended for best results, especially with power tools. A standard Phillips driver will also engage these screws.
The screws feature a black oxide or black zinc coating that provides corrosion resistance, reduces light reflection, and gives a clean appearance for visible assemblies. This finish is commonly used in electronics builds, PC cases, and dark-panel enclosures where a silver screw head would stand out.
A Pozi or Phillips precision screwdriver matched to the screw size: PH000/PZ000 for M1.0–M1.2, PH00/PZ00 for M1.4–M1.6, PH0/PZ0 for M2–M2.5, PH1/PZ1 for M3–M4, PH2/PZ2 for M5–M6. Always use a well-fitting driver to avoid stripping, especially on smaller sizes.
Yes. M1.0–M1.6 are standard sizes for eyeglass frames and micro electronics. M2–M2.5 are common in laptop hinges and keyboard assemblies. M3–M4 suit electronics enclosures and PCB mounting. M5–M6 are used in PC builds and general DIY. Always verify your device’s exact thread spec before ordering.
Yes — these are machine screws, not self-tapping. They require a pre-tapped M-series hole or a matching metric nut in the same thread size. They will not cut their own thread into plastic or metal.
Strength varies by size and material grade. These screws are generally suitable for light-to-medium clamping loads in electronics, enclosures, and general DIY. They are not rated for structural or high-load applications. Do not overtighten smaller sizes — M1–M2 screws can shear if excessive torque is applied.
Available in packs of 1, 10, 50, and 100 pieces depending on the thread size selected. Single-piece packs are ideal for exact replacements; larger packs offer better per-unit value for workshops and production use. Select your preferred quantity using the Amount option above.
