🔩 Black Zinc Flanged Button Head Machine Screws – M2 to M5, Phillips Drive (DIN 967)

These black zinc plated flange screws combine a low‑profile button head with an integrated washer – no more loose washers to drop or forget. The flange distributes clamping pressure evenly, so you get a secure hold without marring the surface. Perfect for automotive trim, electronics chassis, appliances, and DIY projects where a sleek black finish matters. Made from high‑strength carbon steel with a black zinc plating for decent corrosion resistance and a stealthy look. Available in M2, M2.5, M3, M4, M5 diameters, with lengths from 3mm to 16mm. Grab a handful for your next assembly line or weekend build.

✨ Why Choose These Black Zinc Flanged Button Screws

Integrated flange (built‑in washer) – Saves time and ensures consistent clamping force. No extra washers needed. The flange prevents the screw from pulling through softer materials like plastic or thin sheet metal.

Low button head profile – Sits lower than a standard pan head but higher than a countersunk screw. Provides a clean, finished look without needing a countersunk hole.

Black zinc plating – Offers moderate corrosion resistance (better than raw steel) and a uniform black finish that resists fingerprints. Great for dark‑themed builds or automotive under‑hood applications.

High‑strength carbon steel – Stronger than standard low‑carbon steel. Good toughness and machinability. Handles moderate torque without stripping.

Phillips drive for common tool access – Works with any Phillips screwdriver. No special bits required.

Wide size range (M2–M5) & short lengths – Ideal for small electronics, 3D printed parts, RC vehicles, control panels, and light machinery. Lengths from 3mm to 16mm.

💡 Design tip: The flange head also acts as a vibration damper – the wide underside keeps tension better than a standard pan head in applications with light to moderate vibration (fans, small motors).

💬 Frequently Asked Questions – Black Zinc Flanged Button Screws

What’s the advantage of a flanged head over a separate washer + pan head?
Speed and convenience. You never lose the washer, and the flange is permanently attached. It also distributes pressure more evenly than a small pan head, reducing the chance of cracking plastic or denting soft metal. Plus, in tight spaces, you don’t have to juggle a loose washer.
Will black zinc plating rust outdoors?
Black zinc offers mild corrosion resistance – fine for indoor or sheltered outdoor use (garages, covered patios). It will eventually rust if left in direct rain or high humidity for long periods. For outdoor exposure, we recommend stainless steel or hot‑dip galvanized fasteners. These are best for interior or protected applications where the black finish is desired.
What screwdriver size do I need for M2–M5 Phillips?
M2–M2.5 use PH0, M3–M4 use PH1, M5 uses PH2. Using the correct size prevents stripping the cross recess. A PH2 on an M3 screw will likely damage the head.
Can I use these screws with nuts, or only into tapped holes?
Both work. They are standard machine screws, so they fit metric nuts (M2–M5) or threaded holes. The flange can sometimes replace a flat washer when used with a nut – but for critical applications, still use a washer under the nut side.
Are these screws fully threaded or partially threaded?
For lengths up to 10mm, they are usually fully threaded. For longer lengths (12mm, 16mm), there may be a short unthreaded shank under the head. If you need fully threaded for a specific length, please check the product images or contact us.
Do you combine shipping if I buy multiple sizes?
Absolutely. We automatically combine all items in your cart – you pay shipping only once, based on the item with the highest shipping cost. Add all the sizes and quantities you need before checkout. No extra shipping charges for multiple items.
