🔩 Product Overview: M1–M8 Ultra Thin Flat Head Phillips Bolts – A2 Stainless Steel
When every millimeter counts – in slim laptops, medical devices, or flush‑mounted panels – standard countersunk screws can still protrude more than you'd like. These ultra‑thin flat head Phillips machine screws feature a reduced head height, allowing you to achieve an even flatter, more seamless finish. Made from A2 (304) stainless steel, they resist rust and corrosion, making them perfect for electronics, marine instruments, and decorative hardware. Available in metric diameters from M1 all the way up to M8, with various lengths to suit your project. The Phillips drive works with standard precision bits, and the fully threaded design ensures maximum grip in thin materials.
✨ Why These Ultra Thin Flat Head Screws Stand Out
-
Ultra‑thin flat head design – Reduced head height compared to standard countersunk screws. Achieves an even flatter finish for ultra‑slim assemblies.
-
A2 stainless steel (304) – Excellent corrosion resistance for indoor and outdoor use. Won't rust or stain – ideal for marine, kitchen, and medical environments.
-
Full metric range M1 to M8 – From micro M1 for watches and electronics up to M8 for furniture and machinery. One product line covers almost all small‑to‑medium needs.
-
Phillips drive – Standard cross recess works with common #000 to #2 bits. Easy to install with precision screwdrivers.
-
Fully threaded, coarse metric pitch – Standard pitches across all sizes. Threads run the entire length for maximum grip.
-
Precision manufacturing – Clean heads, consistent threads, and a smooth finish. Packaged in plastic bags or cartons.

❓ FAQs – Ultra Thin Flat Head Screws
🔸 What makes these “ultra thin” compared to standard countersunk screws?
Standard countersunk screws (DIN 965) have a certain head height. Our ultra‑thin version reduces that height by approximately 20–30%, allowing the screw to sit even deeper or protrude less. This is critical for ultra‑slim laptops, phones, and tight mechanical assemblies.
🔸 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 as total screw length including the head (standard for countersunk fasteners). For example, an M3 x 8mm screw is 8mm long overall from top to tip.
🔸 Will A2 stainless steel rust in outdoor or coastal environments?
A2 (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 garden furniture, railings, and general outdoor DIY, 304 lasts for years without rust.
🔸 What Phillips screwdriver size works for M1 through M8?
M1–M1.6: use PH000. M2–M2.5: use PH00. M3–M4: use PH1. M5–M6: use PH2. M8: use PH2 or PH3 (PH2 works for most). Using the correct size prevents stripping – invest in a precision screwdriver set for the smaller 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–M8) or a pre‑tapped hole. They are not self‑tapping. For best corrosion resistance, pair them with A2 stainless nuts.
🔸 Are these screws magnetic?
A2 stainless is generally non‑magnetic in its annealed state, but cold forming (thread rolling, head stamping) can make it slightly magnetic. A light magnetic response is normal and does not affect corrosion resistance.
