🔩 Product Overview: M2 & M2.5 Brass Countersunk Phillips Screws (4–12mm)
If you’re restoring an antique radio, building a model ship, or just need a screw that won’t rust or interfere with magnets, these solid brass Phillips flat head machine screws are exactly what you’re after. Available in M2 and M2.5 diameters and lengths from 4mm up to 12mm, they’re fully countersunk – meaning the head sits flush with the surface for a smooth, professional finish. The brass material gives you natural corrosion resistance, a warm golden look, and zero magnetic interference. Perfect for woodworking, decorative hardware, electrical terminals, and any project where you want strength without the industrial grey of steel.
✨ Why Brass Countersunk Phillips Screws Belong in Your Workshop
-
Solid brass construction – Naturally corrosion‑resistant, non‑magnetic, and develops a classic patina over time. No plating to chip or wear off.
-
Phillips drive with flat countersunk head – The cross recess centers your driver, and the 82° flat head sinks perfectly into a countersunk hole. Leaves a flush, snag‑free surface.
-
Metric sizes M2 and M2.5 – Tiny but tough. Ideal for small electronics, jewelry boxes, model making, and instrument repair.
-
Lengths from 4mm to 12mm – Choose exactly what you need: 4mm, 5mm, 6mm, 8mm, 10mm, or 12mm. Short for thin panels, longer for through‑hole applications.
-
Excellent machinability and toughness – Brass is easy to work with, yet strong enough for most indoor fastening. Also safe and environmentally friendly.
-
Brand: Goobetter, made in China – Consistent quality and thread accuracy. No surprises when you go to screw them in.

❓ FAQs – M2 / M2.5 Brass Countersunk Screws
🔸 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 (top of the flat head to the tip). For example, an M2 x 8mm screw is 8mm long overall. This matches typical countersunk screw measurement conventions.
🔸 Will brass screws rust or corrode?
Brass does not rust like steel. It can develop a darker patina or slight greenish tint (verdigris) over many years in damp conditions, but this is a surface change that doesn’t weaken the screw. For indoor use, they’ll stay golden for a long time. For outdoor use, they outperform plain steel but aren’t as corrosion‑resistant as stainless – best for sheltered or decorative exterior work.
🔸 What Phillips screwdriver size do I need for M2 and M2.5?
For M2 and M2.5 brass screws, use a PH0 or PH00 precision screwdriver. PH0 is usually best. Avoid using a PH1 – it will be too large and can strip the recess. A jeweler’s screwdriver set works perfectly.
🔸 Can I use these screws in wood, plastic, or metal?
These are machine screws – best used with a matching nut or into a pre‑tapped metal hole. For wood or soft plastic, drill a pilot hole and use them as wood screws; the full thread will grip well. For best results in soft materials, consider adding a threaded insert or using a nut on the back side.
🔸 Do these screws come with nuts or washers?
They are sold as screws only. However, M2 and M2.5 brass or stainless steel nuts and washers are available separately. For a flush countersunk finish, you don’t need a washer – the flat head itself sits flush in a tapered hole.
🔸 Are these screws magnetic? Will they interfere with electronics?
Brass is completely non‑magnetic. That’s one of the main reasons to choose them over steel – perfect for sensitive electronic equipment, MRI rooms, compass housings, or any application where stray magnetism is a problem.
