Solid Brass Pan Head Phillips Machine Screws — M2 to M6, All Sizes

Solid brass pan head Phillips machine screws are the go-to fastener for electronics, electrical enclosures, decorative hardware, musical instruments, marine fittings, and any application where corrosion resistance, non-magnetic properties, or a warm metallic finish matters. These screws cover six metric diameters — M2, M2.5, M3, M4, M5, and M6 — with lengths from 4mm to 45mm depending on the diameter, and pack quantities from 10 to 100 pieces. Whether you need a small quantity for a repair or a bulk pack for production, you can select exactly what you need.

The round pan head profile sits above the surface when installed, providing a large bearing surface without requiring a countersunk hole. Material is solid brass (CuZn alloy) for good corrosion resistance, electrical conductivity, and a distinctive gold-tone appearance. Drive is Phillips, compatible with standard PH0, PH1, and PH2 screwdrivers depending on screw size. Thread is ISO metric coarse pitch, compatible with standard metric nuts, threaded inserts, and tapped holes.

Typical applications include PCB and electronics assembly, electrical panel hardware, marine and coastal fittings, furniture and cabinet hardware, musical instrument repair, clock and watch mechanisms, decorative joinery, and any application requiring a non-magnetic, non-sparking, corrosion-resistant M2–M6 fastener.

🔩 Compatibility: ISO metric coarse pitch — M2 (0.4mm pitch), M2.5 (0.45mm), M3 (0.5mm), M4 (0.7mm), M5 (0.8mm), M6 (1.0mm). Phillips drive (PH0/PH1/PH2 depending on size). Requires pre-tapped hole or nut. Not self-tapping. No countersinking required.

✅ Key Features of These Solid Brass Pan Head Phillips Machine Screws

🟡Solid Brass Construction — Corrosion Resistant & Non-Magnetic — Made from solid brass (CuZn alloy), not plated steel. Brass provides good corrosion resistance, electrical conductivity, non-magnetic properties, and a distinctive gold-tone finish that does not rust or corrode in most environments.
📐Six Metric Sizes — M2 to M6 — Available in M2, M2.5, M3, M4, M5, and M6 diameters with multiple lengths per size, covering the most common small metric machine screw sizes for electronics, hardware, and general fabrication.
🔧Round Pan Head — No Countersinking Required — The pan head profile sits above the surface when installed, providing a large bearing surface and a clean, finished appearance without requiring a countersunk hole. Suitable for through-hole and tapped-hole installations.
🔩Phillips Drive — PH0 / PH1 / PH2 — Compatible with standard Phillips screwdrivers and power tool bits. Use PH0 or PH1 for M2–M2.5, PH1 or PH2 for M3–M4, and PH2 for M5–M6. Using the correct bit size is important to avoid cam-out on softer brass heads.
⚡Electrically Conductive — Brass is an excellent electrical conductor, making these screws suitable for grounding connections, electrical panel hardware, and PCB standoff applications where conductivity is required.
📦Flexible Pack Quantities — 10 to 100 Pieces — Choose from 10, 20, 50, or 100 pieces per pack to match your project scale. Larger packs offer better per-unit value for production runs and bulk stocking.

⚠️ Note: These are machine screws — they require a pre-tapped hole, threaded insert, or nut. They are not self-tapping. Brass is softer than steel; use the correct Phillips bit size and avoid over-torquing to prevent head damage. Not recommended for high-load structural applications.

❓ Frequently Asked Questions

What are solid brass machine screws used for?

Solid brass pan head Phillips machine screws are used in applications requiring corrosion resistance, electrical conductivity, or a decorative finish. Common uses include electronics and PCB assembly, electrical enclosures, marine fittings, furniture hardware, musical instruments, clocks, and any application where a non-magnetic, non-sparking fastener is needed.

Are brass screws stronger than stainless steel screws?

No. Brass is softer than stainless steel and has lower tensile strength. Brass screws are chosen for their corrosion resistance, electrical conductivity, non-magnetic properties, and appearance — not for high-strength structural applications. For high-load or high-stress applications, stainless steel or alloy steel fasteners are more appropriate.

What screwdriver do I need for pan head Phillips screws?

The correct Phillips bit size depends on the screw diameter: M2 and M2.5 typically use PH0 or PH1; M3 and M4 typically use PH1 or PH2; M5 and M6 typically use PH2. Using the correct bit size is important to avoid cam-out and head damage, especially with softer brass screws. Always use a well-fitting bit and avoid power tools at high torque settings.

Are these screws compatible with standard metric nuts and threaded inserts?

Yes. These are ISO metric coarse-pitch machine screws. They are compatible with standard metric nuts, threaded inserts, and tapped holes of the corresponding size. They are not compatible with UNC/UNF (inch) threads or fine-pitch metric variants. Always verify the thread pitch and hole diameter before ordering.

Can I use brass screws outdoors?

Brass has good corrosion resistance in most outdoor environments and is commonly used in marine and coastal applications. However, brass can dezincify in certain aggressive environments (acidic soils, some water types). For harsh marine or highly corrosive environments, consider A4 stainless steel. For general outdoor use, brass performs well and maintains its appearance over time.

What is the difference between a pan head and a countersunk head screw?

A pan head screw has a flat top with slightly rounded edges and sits above the surface when installed — no countersinking required. A countersunk (flat head) screw has a tapered head that sits flush with or below the surface when installed in a countersunk hole. Pan head screws are used where a flush finish is not required and where the raised head provides a larger bearing surface.

Are these screws self-tapping?

No. These are machine screws, not self-tapping screws. They require a pre-tapped hole, threaded insert, or nut. They will not cut their own thread into material. For self-tapping applications, a different screw type is required.

How many pieces come in each pack?

Pack quantities available are 10, 20, 50, and 100 pieces. Select your preferred quantity using the "Amount" selector. Larger packs offer better per-unit value for production or bulk use.
