🔩 Product Overview: M1.6–M4 Phillips Wafer Flat Head Machine Screws – 304 Stainless Steel
If you need a low‑profile screw that sits nearly flush without requiring a countersunk hole, these Phillips wafer head machine screws are the ideal choice. The wide, flat underside (wafer head) distributes clamping force evenly, making them perfect for plastic laptop cases, thin sheet metal, and panel mounting. Made from 304 stainless steel, they offer excellent rust, oxidation, and corrosion resistance – suitable for both indoor and light outdoor use. Fully threaded with standard coarse metric pitch, available in diameters M1.6, M2, M2.5, M3, and M4, with lengths from 3mm up to 70mm (measured under the head). The Phillips drive allows quick installation with standard PH0, PH1, or PH2 bits. Choose your size and length – ideal for electronics, furniture, appliances, and general DIY.
✨ Why Choose 304 Stainless Steel Wafer Head Screws
-
Wafer flat head design – Wide, low‑profile head sits nearly flush without countersinking. Great for plastic and thin materials where a standard countersunk screw would require a tapered hole.
-
304 stainless steel (A2 grade) – Excellent rust, oxidation, and corrosion resistance. Durable and wear‑resistant for long service life.
-
Phillips drive – Standard cross slot pattern allows fast installation with common Phillips bits – saves time and effort.
-
Wide size range: M1.6, M2, M2.5, M3, M4 – Covers everything from micro electronics (M1.6) up to small machinery and furniture (M4).
-
Extensive length options: 3mm to 70mm (under head) – Choose from many lengths to match your exact application. Fully threaded for maximum grip.
-
Deep, neat, and clear threads – Even force distribution, not easy to slip. Smooth, burr‑free finish for reliable fastening.
-
Wide application range – Electronics, furniture decoration, appliances, light machinery, and general industrial use.

❓ FAQs – Wafer Head Stainless Steel Screws
🔸 What is the difference between a wafer head and a countersunk flat head?
A wafer head (also called flat washer head) has a wide, flat underside and sits nearly flush on the surface without requiring a countersunk hole. A countersunk flat head requires a tapered hole to sit flush. Wafer heads are ideal for plastic, thin metal, or where you cannot countersink.
🔸 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 wafer head. For example, an M3 x 10mm screw has a 10mm threaded shank.
🔸 Will 304 stainless steel rust outdoors or in coastal environments?
304 stainless is highly resistant to moisture, rain, and humidity – perfect for most outdoor use. For direct saltwater immersion or heavy coastal spray, A4 (316) stainless is better, but for general outdoor furniture, appliances, and covered marine use, 304 lasts for years without rust.
🔸 What Phillips screwdriver size works for M1.6 through M4?
M1.6–M2: use PH00 or PH0. M2.5–M3: use PH0 or PH1. M4: use PH1. A precision screwdriver set with interchangeable bits is recommended for the smallest sizes.
🔸 Can I use these screws with nuts, or are they self‑tapping?
These are standard machine screws – they require a matching metric nut (M1.6–M4) or a pre‑tapped hole. They are not self‑tapping. For best corrosion resistance, pair them with 304 stainless nuts.
🔸 What lengths are available for each diameter?
We offer a wide range of lengths from 3mm to 70mm. Not every length may be available for every diameter – please select your desired size and length from the dropdown options. If you need a specific combination not listed, contact us.
