🔩 Product Overview: T3–T50 Torx Pan Head Screws – M1.4 to M10, A2 Stainless Steel
If you're done with Phillips drivers slipping or hex keys rounding out, Torx is the answer. These pan head machine screws feature a Torx (hexalobular) internal drive – the star‑shaped recess gives you full contact engagement, zero cam‑out, and the ability to apply serious torque without stripping. Available in metric diameters from tiny M1.4 all the way up to M10, and lengths from 3mm to 100mm (measured under the head), this single product line covers everything from delicate electronics to heavy‑duty machinery. Made from A2 (304) stainless steel, they're waterproof, rustproof, and built to last in construction, furniture, automotive, medical, and marine environments. The low‑profile pan head sits flush on surfaces, and the Torx drive works with T3 through T50 bits – one screwdriver set handles them all.
✨ Why Torx Pan Head Screws Are a Game Changer
-
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.
-
A2 stainless steel (AISI 304) – Excellent corrosion resistance for indoor and outdoor use. Waterproof, rustproof, and durable for long‑term installations.
-
Pan head design – Low‑profile rounded head with a flat bearing surface. Sits flush on panels, distributes clamping force evenly, and gives a clean, professional finish.
-
Massive size range: M1.4 to M10 – From micro screws for electronics (M1.4, M1.6, M2) up to heavy M10 bolts for industrial equipment. One stop for almost every metric Torx pan head need.
-
Lengths 3mm–100mm (under head) – Short screws for thin panels, long ones for thick materials. Choose exactly what your project requires.
-
Standard coarse metric threads, fully threaded – Consistent pitch across all diameters (see table). Threads run the entire shank length.
-
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. No guesswork.
-
Wide application range – Construction, furniture manufacturing, bicycles, automotive, medical devices, electronics, anti‑theft hardware, home appliances, and daily installations.

❓ FAQs – Torx Pan Head Screws (M1.4–M10, 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 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 pan head. For example, an M6 x 20mm screw has a 20mm threaded shank below the head.
🔸 Will A2 (304) 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, 304 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 pan 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 Torx bit do I need for each size?
See the table above: M1.4 uses T3, M1.6 uses T4, M2 uses T6, M2.5 uses T8, M3 uses T10, M4 uses T20, M5 uses T25, M6 uses T30, M8 uses T45, M10 uses T50. A good quality Torx bit set (T3–T50) will cover all these.
🔸 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.
