🔩 Product Overview: M3 Button Head Flanged Phillips Machine Screws – Nickel Plated Carbon Steel (5–20mm)
These M3 button head machine screws feature an integrated flange that acts as a built‑in washer – no need for a separate flat washer. The low‑profile domed head sits close to the surface, providing a clean, modern look while the flange distributes clamping force evenly and protects the workpiece. Made from carbon steel with a bright nickel plating, they offer good corrosion resistance and a polished silver finish. Fully threaded with standard M3 coarse pitch (0.5mm), and available in lengths from 5mm to 20mm (measured under the head). The Phillips drive works with standard PH1 bits for easy installation. 100% brand new, high quality, and affordable – perfect for furniture, electronics, appliances, automotive trim, and general assembly.

❓ FAQs – M3 Flanged Button Head Screws
🔸 What is the advantage of a flanged button head over a regular pan head?
The integrated flange acts as a built‑in washer. It spreads the clamping force over a larger area, protecting the surface from damage and preventing the screw head from pulling through soft materials. The low‑profile button head also provides a cleaner, more finished appearance than a standard pan head.
🔸 Are these screws fully threaded? How is length measured?
Yes – they are fully threaded from just under the head to the tip. Length is measured from the underside of the head (the flat bearing surface) to the tip, not including the button head or flange. For example, an M3 x 10mm screw has a 10mm threaded shank.
🔸 Will the nickel plating rust or wear off?
Nickel plating provides good corrosion resistance for indoor and light outdoor use. It holds up well for furniture, electronics, and appliances. With repeated driving, the recess may show some wear, but the overall finish is durable for most general use. For constant moisture or saltwater, we recommend stainless steel.
🔸 What Phillips screwdriver size should I use for M3 screws?
Use a PH1 Phillips screwdriver bit. This provides the best engagement and prevents stripping. A quality PH1 bit is standard for M3 screws.
🔸 Can I use these screws with nuts, or are they self‑tapping?
These are standard machine screws – they require a matching M3 metric nut or a pre‑tapped hole. They are not self‑tapping. For best results, pair them with steel or stainless M3 nuts. The flange replaces the need for a washer on the screw side.
🔸 What lengths are available for M3 flanged button head screws?
We offer M3 lengths from 5mm to 20mm: 5, 6, 8, 10, 12, 16, and 20mm. Please select your desired length from the dropdown options. If you need a length not listed, contact us.
