When a standard Phillips or slotted screw strips under torque, the job stops. These A2 stainless steel Torx pan head machine screws are built to prevent exactly that. The six-lobe Torx drive transfers torque more efficiently than conventional drives, dramatically reducing cam-out risk — whether you're assembling electronics, securing enclosures, building furniture, or working on precision equipment where a stripped screw head is not an option.
Machined from A2 (304) stainless steel, these screws deliver reliable corrosion resistance for indoor, humid, and light outdoor applications without the rust concerns of standard carbon steel fasteners. Available in five metric diameters — M2, M2.5, M3, M4, M5, M6, and M8 — with multiple lengths per diameter, and in pack sizes of 1, 5, 10, or 100 pieces to match any project scale from a single repair to a full production run.
These Torx pan head machine screws are a natural fit for electronics enclosures and computer hardware where cam-out resistance protects sensitive components; for furniture and cabinetry assembly where a low-profile head sits cleanly on the surface; for precision instruments and small appliances requiring reliable, repeatable fastening; and for any application where stainless steel corrosion resistance is required alongside a secure, high-torque drive.

Torx (also called six-lobe or star drive) is a six-pointed star-shaped drive recess. It provides more contact area than Phillips or slotted drives, which reduces cam-out and allows higher torque transfer. The correct bit size depends on the screw diameter: T6 for M2, T8 for M2.5, T10 for M3, T20 for M4, T25 for M5, T30 for M6, and T40 for M8. Always match the bit to the screw to avoid stripping the recess.
A2 stainless steel (also known as 304 or 18-8 stainless) is an austenitic grade that offers good corrosion resistance in most indoor and light outdoor environments. It performs well in humid conditions, light rain exposure, and general-purpose applications. For marine environments, coastal locations, or prolonged saltwater exposure, A4 (316) stainless steel is generally recommended for superior corrosion resistance.
A2 stainless steel is generally considered to have low magnetic permeability in its annealed state, though it may exhibit slight magnetic properties after cold working during manufacturing. For applications requiring strictly non-magnetic fasteners — such as MRI equipment or sensitive electronic instruments — verify compatibility with your specific application requirements.
These are standard ISO metric machine screws with coarse pitch threads. The size designation (M2, M2.5, M3, M4, M5, M6, M8) refers to the nominal thread diameter in millimeters. They are compatible with standard metric nuts, threaded inserts, and tapped holes manufactured to ISO metric thread standards. They are not compatible with imperial (UNC/UNF) threads.
Pan head screws feature a low-profile, slightly domed head with a flat bearing surface. The head sits on top of the material surface rather than flush with it — no countersinking required. Pan heads provide a larger bearing surface than countersunk heads, making them suitable for applications where a flush finish is not required but a secure, low-profile fastening is needed.
Choose based on your project scale: 1 piece for testing or a single repair, 5 pieces for small projects, 10 pieces for medium builds, and 100 pieces for larger production runs or workshop stock. Larger packs offer better value per screw. Select your preferred size and quantity from the options above.
Yes — the smaller sizes (M2, M2.5, M3) are commonly used in electronics enclosures, computer hardware, precision instruments, and small appliances. The Torx drive is particularly well-suited for these applications because it reduces the risk of cam-out that could damage sensitive components or surrounding surfaces. The stainless steel construction also avoids the corrosion concerns of standard carbon steel fasteners in humid equipment environments.
