🔩 M2–M8 Hex Socket Pan Head Screws – A2 Stainless Steel, Metric, Fully Threaded (3–60mm Lengths)

You’re assembling a 3D printer, mounting a part on a CNC machine, or building a piece of custom furniture – and you want a clean, low‑profile head with a strong, reliable hex drive. These stainless steel pan head screws feature a hex socket (Allen) drive, allowing you to apply high torque without slipping. The pan head provides a wide bearing surface that sits neatly above the material – no countersinking required. Made from A2 stainless steel (304), they resist rust and corrosion indoors and out. Available in M2 through M8 diameters, with lengths from 3mm to 60mm (measured under the head). Fully threaded for maximum grip. Perfect for electronics, machinery, automotive trim, and DIY projects where both strength and appearance matter.

✨ Key Features – Hex Socket Pan Head Machine Screws (A2 Stainless)

🔘 Pan head design – Low profile with a wide bearing surface. Ideal for soft materials like plastic, wood, and sheet metal. No countersinking needed.
🔧 Hex socket (Allen) drive – Allows high torque without cam‑out. Clean, recessed drive doesn’t collect dirt.
🛡️ A2 stainless steel (304) – Excellent corrosion resistance, oxidation resistance, and heat resistance. High strength and toughness.
📏 Metric sizes M2, M2.5, M3, M4, M5, M6, M8 – Covers miniature electronics up to medium machinery and furniture.
📐 Lengths from 3mm to 60mm (under head) – Fully threaded for maximum grip. Select exact length from dropdown.
✨ Clean, natural finish – No added coatings; the silver stainless steel look is professional and consistent.
🏭 Widely used – 3D printers, CNC machines, electronics enclosures, furniture, automotive trim, and marine hardware.

📋 Material – A2 Stainless Steel (304 / 18-8)

Property	Benefit
Corrosion resistance	Excellent in humid, outdoor, and light marine environments. Won’t rust like carbon steel.
Strength	High tensile strength (A2‑70 ~700 N/mm²). Durable and impact resistant.
Temperature resistance	Good heat resistance; maintains strength in high‑temperature applications.
Magnetic	Almost non‑magnetic (slightly magnetic after cold working – normal for 304).

❓ Frequently Asked Questions – Hex Socket Pan Head Screws

1. How do I measure the length of a pan head screw?

For pan head screws (including these hex socket pan heads), the length is measured from the underside of the head (the flat bearing surface) to the tip. The head itself is NOT included. So an “M5 x 20mm” screw has a 20mm long threaded shaft under the head. This matches the lengths shown in our dropdown.

2. Are these screws fully threaded? What about longer lengths like 60mm?

Yes – all M2 to M8 screws in this range, up to 60mm length, are fully threaded from under the head to the tip. This gives you maximum grip even in shallow holes or through‑nut applications.

3. What hex key (Allen) size do I need for each screw?

Based on standard hex socket dimensions: M2 and M2.5 use 1.5mm, M3 uses 2.0mm, M4 uses 2.5mm, M5 uses 3.0mm, M6 uses 4.0mm, M8 uses 5.0mm. Always use a good quality hex key that fits snugly to avoid rounding the socket.

4. Can I use these screws outdoors? Will they rust?

A2 stainless (304) is highly corrosion‑resistant and suitable for outdoor use in most environments – including rain, humidity, and coastal areas. For continuous saltwater immersion, A4 (316) is better, but for furniture, machinery, and general outdoor hardware, 304 is excellent and will not rust.

5. Do I need to countersink the hole for these pan head screws?

No – pan head screws are designed to sit on top of the material. They do not require a countersunk hole. Just drill a clearance hole for the thread (or a pilot hole for threading) and the head will rest on the surface, providing a wide bearing area.

6. Can I use these screws with a nut? What size nut fits?

Yes – these are machine screws. Use standard metric nuts of the same thread size (e.g., M3 nut for M3 screw). They will also thread into pre‑tapped holes. They are not self‑tapping – for wood or plastic, drill a pilot hole and use a nut or threaded insert.
