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.\u003c\/p\u003e\n\u003c!-- Key Features List --\u003e\n\u003ch2\u003e✨ Why These M3 Flanged Button Head Screws Are a Smart Choice\u003c\/h2\u003e\n\u003cul class=\"hdiy-features-list\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated flange (built‑in washer)\u003c\/strong\u003e – Eliminates the need for a separate flat 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.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003e🔸 Are these screws fully threaded? How is length measured?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eYes – 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.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003e🔸 Will the nickel plating rust or wear off?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eNickel 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.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003e🔸 What Phillips screwdriver size should I use for M3 screws?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eUse a PH1 Phillips screwdriver bit.

They are not self‑tapping. For best results, pair them with steel or stainless M3 nuts.
