These M1, M1.2, M1.4, M1.6, M1.7, and M1.8 Phillips countersunk flat head machine screws are made for precision work. Choose from carbon steel (with bright nickel, black zinc, or natural finish) or 304 stainless steel – so you get the strength and corrosion resistance your micro‑fastening job demands. The flat head sits flush in countersunk holes, perfect for tight assemblies where every millimeter matters. Whether you're restoring vintage jewelry, repairing a smartphone hinge, or building a miniature model, these tiny screws deliver without stripping or seizing.\u003c\/p\u003e\n\u003c!-- 产品特点列表 --\u003e\n\u003ch2\u003e✨ Why These Micro Countersunk Screws Are a Precision Repair Essential\u003c\/h2\u003e\n\u003cul class=\"hdiy-features-list\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra‑small metric sizes: M1 to M1.8\u003c\/strong\u003e – The hard‑to‑find diameters for eyeglass frames, watch bands, miniature hinges, camera parts, and RC electronics.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhillips drive with flat countersunk head\u003c\/strong\u003e – The cross recess centers your smallest screwdriver, and the 82° flat head sinks flush for a smooth, snag‑free surface.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChoice of carbon steel or 304 stainless steel\u003c\/strong\u003e – Carbon steel for everyday strength (with nickel\/black zinc\/natural plating). 304 stainless for maximum corrosion resistance in damp or outdoor mini‑projects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully threaded, GB standard\u003c\/strong\u003e – Threads run the entire length.

If a device uses a screw that looks like a tiny flathead but has a cross recess, it’s likely one of these.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003e🔸 Should I choose carbon steel or stainless steel?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eCarbon steel (with nickel or black zinc plating) is stronger and less expensive – great for indoor repairs, eyewear, and general modeling. 304 stainless is best for moisture resistance (sweat, humidity, occasional water exposure) and where you never want rust. For watch bands or glasses that contact skin, stainless or nickel‑plated carbon steel are both fine.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003e🔸 What screwdriver size works for these tiny screws?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eYou’ll need a precision Phillips #000 or #00 (PH000 or PH00). A jeweler’s screwdriver set with interchangeable bits is essential. Never force a larger bit – you’ll strip the recess instantly. For M1 and M1.2, a PH000 is safest. For M1.4–M1.8, a PH00 often works.\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 under the head to the tip. Length is measured as total screw length including the head (standard for countersunk screws). For example, an M1.4 x 4mm screw is 4mm overall from top of head to tip.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003e🔸 Will the black zinc finish wear off over time?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eBlack zinc provides a dark, corrosion‑resistant coating. With normal use, it may show light wear at the tip or on the recess after repeated driving, but it holds up well for most hobby and repair applications. If you need an invisible dark fastener for a black anodized part, it’s a good choice.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003e🔸 Can I use these screws with nuts, or are they self‑tapping?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eThese are machine screws – they require a matching metric nut (e.g., M1, M1.2, etc.) or a pre‑tapped hole. They are not self‑tapping. For plastic or soft wood, you can drill an undersized pilot hole and use them as wood screws, but a nut or insert is more reliable in tiny sizes.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"HomeDIYer","offers":[{"title":"M1×2.6 D=2【Stainless steel】 \/
