A2 Stainless Steel Torx Pan Head Machine Screws — Precision Metric Fasteners for Every Project

Stripped screws, cam-out frustration, and rust-prone fasteners are the enemy of any clean build. Whether you're assembling electronics, fabricating metal brackets, or maintaining outdoor equipment, you need fasteners that hold tight and resist corrosion without fail. These A2 stainless steel Torx pan head machine screws are engineered for exactly that.

Each screw features a round pan head profile with a Torx (star) drive recess, machined from A2 (304) stainless steel. Available in metric thread sizes M1.4 through M10, with lengths ranging from 3mm to 100mm depending on diameter. Sold in packs of 10 or 20 pieces for flexible ordering.

Ideal for electronics enclosures, robotics frames, HVAC panels, marine hardware, DIY furniture assembly, and precision instrument mounting — anywhere a reliable, corrosion-resistant metric fastener is required.

Compatible with standard metric Torx bits (T-series). Suitable for use with steel, aluminum, plastic, and wood substrates.

❓ Frequently Asked Questions

What sizes are available for these Torx pan head machine screws?

These screws are available in metric thread sizes M1.4, M1.6, M2, M2.5, M3, M4, M5, M6, M8, and M10, with lengths typically ranging from 3mm to 100mm depending on the diameter. Select your exact size using the variant options above.

What material are these machine screws made from?

These screws are made from A2 stainless steel (also known as 304 stainless steel), which offers excellent corrosion resistance and is suitable for both indoor and outdoor applications.

What drive type do these screws use?

These screws feature a Torx (star-shaped) drive, which provides better torque transfer and reduces cam-out compared to Phillips or slotted drives. A T-series Torx bit is required for installation.

Are these screws suitable for outdoor or marine use?

A2 stainless steel offers good corrosion resistance and is generally suitable for outdoor environments. For highly corrosive or marine environments, A4 (316) stainless steel is typically recommended.

How do I choose the right screw length?

As a general rule, the screw length should provide at least 1.5× the thread diameter of engagement in the mating material. For example, an M4 screw should typically engage at least 6mm of thread for a secure hold.

What is the head style of these screws?

These screws have a pan head (round head) profile, which provides a low-profile, domed appearance and a wide bearing surface — ideal for general fastening applications where a flush or countersunk head is not required.

Can I use these screws with a standard drill or screwdriver?

Yes, you can use a standard drill or manual screwdriver fitted with the appropriate Torx bit. For smaller sizes (M1.4–M2), a precision screwdriver set is recommended to avoid stripping the drive recess.

Are these sold in sets or individually?

These screws are sold in packs of 10 or 20 pieces per order. Select your preferred size and quantity using the variant options above.
