🔩 M1–M10 Pozi / Phillips Button Head Machine Screws – Black A2 Stainless Steel (304), Fully Threaded
From tiny M1 screws for eyeglass repair up to M10 for heavy‑duty assemblies, this black stainless steel button head screw range covers it all. The low, rounded button head sits flush(ish) and looks great on visible surfaces — no sharp edges to snag fingers or fabric. Made from A2 (304) stainless steel with a black finish (coated or blackened), these screws resist rust and add a sleek, dark accent to your project. Choose between Pozidriv or Phillips drive (our screws work with both, but Pozi gives better bite). Fully threaded from end to end, perfect for precision adjustments, electronics, 3D printers, RC models, and furniture. And yes, we offer trade discounts for bulk orders — just contact us.
✨ Why These Black Button Head Screws Are a Cut Above
Wide size range: M1 to M10 – Includes tiny M1, M1.2, M1.4, M1.6, M1.7, M2, M2.5, M3, M4, M5, M6, M8, M10. Whatever your metric need, we likely have it.
Button head with low profile – The head is rounded and low‑height, ideal for applications where a pan head is too tall or a flat head can’t be countersunk. Provides a clean, almost flush appearance.
Pozi / Phillips compatible drive – The cross recess works with both Pozidriv (recommended) and Phillips drivers. Pozidriv bits give better torque transfer and less cam‑out, especially at small sizes.
Black A2 stainless steel (304) – Corrosion‑resistant base with a black finish (coating or black oxide). Rust protection plus a sleek, non‑reflective look. Great for automotive trim, camera rigs, or dark‑themed builds.
Fully threaded shank – Thread runs the entire length under the head. Provides maximum grip in thin materials or when precise depth adjustment is needed.
Precise dimensions to DIN / metric standards – Head diameters and thicknesses follow standard metric specs (see table below). Consistent quality across all sizes.
💡 Design tip: The button head is often used in socket head cap screw applications where a lower profile is desired. Perfect for 3D printer build plates, camera mounts, and under‑desk cable management.
💬 Frequently Asked Questions – Black Stainless Button Head Screws
What’s the difference between Pozi and Phillips? Which driver should I use?
Phillips drivers have pointed tips and tapered flanks, designed to cam out under torque. Pozi (Pozidriv) bits have blunt tips and parallel flanks, plus four extra contact points. They lock in much better and reduce stripping – especially critical in tiny M1-M3 screws. Our screws accept both, but we strongly recommend a Pozi driver (PZ0 for M1-M2, PZ1 for M3-M5, PZ2 for M6-M10) for best results. A Phillips bit will work, but you may slip.
Is the black finish just paint? Will it scratch off?
The black coating is a durable oxide or plating (varies by batch). It resists normal handling and installation scratches better than cheap paint. However, any screw can show wear on the drive recess and thread tips over time. For maximum abrasion resistance, consider our black zinc plated carbon steel option – but that won't have stainless corrosion resistance. This black stainless offers a good balance of looks and rust protection.
Will these screws rust if used outdoors?
The base material is A2 (304) stainless, so they are highly corrosion resistant. The black coating adds an extra layer. They will hold up well in rain, humidity, and even coastal air – much better than ordinary steel screws. For permanent saltwater immersion, upgrade to A4 (316) stainless (not available in black here). For garden furniture, outdoor signs, or bike accessories, these are perfect.
Are these screws fully threaded? Can I get partial threads?
Yes – all screws in this range are fully threaded from just under the head to the tip. Partial thread (shoulder) screws are not offered here. If you need a specific length with a plain shank, please contact us for custom orders.
Do you offer bulk / trade discounts?
Absolutely. We offer volume discounts for larger quantities – just contact us with your desired sizes and quantities. We can quote trade prices and even drop‑ship for businesses. The more you order, the better the price per piece.
What nut or thread size matches these screws?
These are standard metric coarse threads. Use a matching metric nut (M1 nut for M1 screw, M2 nut for M2, etc.) or a tapped hole of the same thread. Standard thread pitches are as listed in the table above (e.g., M6 uses 1.0mm pitch).
