🔩 Product Overview: Pan Head Machine Screws – M1 to M2.5, A2 Stainless Steel (304)
If you're working on miniature electronics, watches, cameras, or precision instruments, you need tiny screws that are strong, corrosion‑resistant, and easy to drive. These M1, M1.2, M1.4, M2, and M2.5 Phillips pan head machine screws are made from A2 (304) stainless steel – offering excellent rust resistance, high strength, and a clean, natural silver finish. The low‑profile round head sits flush on surfaces and distributes clamping force evenly, while the Phillips drive works with precision PH0 or PH00 bits. Fully threaded with standard coarse metric pitch, and length is measured from under the head (head not included). Available in various lengths – select your size from the options. Perfect for electronics repair, hobby projects, medical devices, and precision engineering.
✨ Why Choose A2 Stainless Steel Micro Pan Head Screws
-
A2 stainless steel (304 grade) – Excellent corrosion resistance, high strength, and good toughness. Natural silver finish – no plating to chip or wear.

❓ FAQs – Micro Pan Head Stainless Steel Screws
🔸 What devices commonly use M1 to M2.5 screws?
These tiny screws are found in watches and watch bands, eyeglass hinges, camera lens mounts, drone motors, smartphone internal brackets, hearing aids, medical devices, and miniature model making. They are also used in high‑end pens, jewelry, and precision instruments.
🔸 How is length measured for these pan head screws?
Length is measured from the underside of the head (the flat bearing surface) to the tip, not including the pan head. For example, an M2 x 8mm screw has an 8mm threaded shank. This matches the product specification "excluding head".
🔸 Will A2 (304) stainless steel rust?
304 stainless is highly resistant to moisture, humidity, and most indoor environments. It will not rust under normal use. For direct saltwater or chemical exposure, A4 (316) stainless is recommended, but for electronics and general hardware, 304 is excellent.
🔸 What Phillips screwdriver size do I need for these micro screws?
For M1 to M2, use a PH00 precision Phillips bit. For M2.5, a PH0 or PH00 works. A high‑quality precision screwdriver set with sharp bits is essential to avoid stripping the tiny recess. Never use a worn or oversized driver.
🔸 Can I use these screws with nuts, or are they self‑tapping?
These are standard machine screws – they require a matching metric nut (M1–M2.5) or a pre‑tapped hole. They are not self‑tapping. For best results, use steel or brass nuts of the same thread size.
🔸 What lengths are available for each diameter?
We offer a range of lengths – typical ranges: M1–M1.4: 2–8mm, M2: 3–12mm, M2.5: 4–16mm. Please select your desired size and length from the dropdown options. If you need a specific combination not listed, contact us.
