🔩 Product Overview: M1.4–M12 Torx Countersunk Screws (A2 Stainless Steel)
If you’re tired of stripping tiny Phillips heads or want a tamper‑resistant fastener that actually stays put, these A2 stainless steel Torx countersunk screws are the upgrade you need. The internal hexalobular (star) drive gives you full contact engagement – no cam‑out, even at high torque. Available in metric diameters from M1.4 all the way up to M12 and lengths from 3mm to 100mm, this single product page covers everything from delicate electronics to heavy‑duty machinery. The flat 82° countersunk head sits flush with the surface, perfect for professional assemblies where a smooth finish matters. Made to DIN 965 / ISO 14581 standards from Grade A2 (304) stainless, they’re waterproof, rustproof, and built to last in construction, furniture, automotive, medical, or marine environments.
✨ Why Torx Drive Countersunk Screws Are a Step Above the Rest
-
Torx (hexalobular) internal drive – The star‑shaped recess eliminates cam‑out, distributes torque evenly, and allows higher tightening forces without damaging the drive. Perfect for power tools and high‑vibration assemblies.
-
Countersunk flat head (DIN 965) – Sits completely flush with the surface. No snagging, no protruding heads – ideal for panels, flooring, and any application requiring a smooth finish.
-
A2 stainless steel (AISI 304) – Excellent corrosion resistance for indoor and outdoor use. Waterproof, rustproof, and durable for long‑term installations.
-
Massive size range: M1.4 to M12 – From micro screws for electronics (M1.4, M1.6, M2) up to heavy M12 bolts for industrial equipment. One stop for almost every metric Torx countersunk need.
-
Lengths 3mm–100mm (measured from head) – Short screws for thin panels, long ones for thick materials. Choose exactly what your project requires.
-
Standard coarse metric threads – Consistent pitch across all diameters: M1.4x0.3, M1.6x0.35, M2x0.4, M2.5x0.45, M3x0.5, M4x0.7, M5x0.8, M6x1.0, M8x1.25, M10x1.5, M12x1.75.
-
Torx wrench sizes clearly mapped – T3 for M1.4, T4 for M1.6, T6 for M2, T8 for M2.5, T10 for M3, T20 for M4, T25 for M5, T30 for M6, T45 for M8, T50 for M10, T55 for M12. No guesswork.
-
Wide application range – Construction, furniture manufacturing, bicycles, automotive, medical devices, electronics, anti‑theft hardware, home appliances, and daily installations.

❓ FAQs – Torx Countersunk Screws (A2 Stainless)
🔸 Why choose Torx over Phillips or hex drive?
Torx (hexalobular) has vertical sidewalls that prevent cam‑out – the driver doesn’t push out of the recess under torque. This allows higher tightening forces without stripping, reduces fastener damage, and makes them ideal for power tool assembly. Once you switch to Torx, you’ll wonder why you ever used Phillips.
🔸 Are these screws fully threaded? How is length measured?
Yes – they are fully threaded from under the head to the tip. Length is measured including the head (total screw length). For example, an M6 x 20mm screw is 20mm long overall from the top of the countersunk head to the tip. This matches DIN 965 measurement standards.
🔸 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 marine exposure, A4 (316) stainless is better, but for garden furniture, railings, and general outdoor DIY, A2 lasts for years without rust.
🔸 Can I use these screws in wood or plastic, or only with nuts?
These are machine screws – best used with a matching nut or into a pre‑tapped metal hole. For wood or soft plastic, you can drill a pilot hole and use them as wood screws (the countersunk head works well), but for maximum strength, use a threaded insert or a nut on the back side.
🔸 Do you offer matching nuts or washers in A2 stainless?
These screws are sold individually, but A2 stainless steel nuts, flat washers, and lock washers are available separately in our store. Search for “A2 stainless nuts” or contact us for a matching set recommendation.
🔸 What lengths are available for each diameter?
Lengths vary by diameter – typical ranges: M1.4–M2: 3–12mm; M2.5–M4: 4–30mm; M5–M6: 6–60mm; M8–M10: 10–80mm; M12: 16–100mm. Select your size and length from the dropdown options on the product page.
🔸 Are bulk discounts available?
Yes – larger quantities are available upon request. Contact us for pricing on volume orders. Perfect for manufacturers, repair shops, or anyone stocking up.
