Brass Phillips Pan Head Self-Tapping Screws — Corrosion-Proof Fasteners for Metal, Wood & Electronics
Brass fasteners bring a classic look and natural corrosion resistance that plated steel can't match. When you're working on furniture, instruments, electrical panels, or decorative metalwork and need a fastener that won't rust, strip, or look out of place — these solid brass Phillips pan head self-tapping screws are the answer. Machined from solid brass, they won't rust, offer excellent electrical conductivity, and deliver a warm, gold-toned finish that's ideal for visible hardware.
The sharp self-tapping thread cuts its own path into sheet metal, wood, plastic, and fiberglass — no pre-tapped hole or nut required in most light-duty applications. Available in five metric diameters — M3, M3.5, M4, M5, and M6 — with lengths ranging from 6 mm to 50 mm (approximately 0.24" to 1.97"), these screws cover the most common fastening needs across a wide range of projects.
A standard Phillips recess makes driving quick and secure, while the pan head sits flush for a clean, professional appearance. Whether you're grounding electronics, assembling cabinetry, or finishing marine trim, these brass self-tapping screws deliver reliable performance with a finish that lasts.
✅ Compatible with sheet metal, softwood, hardwood, plastic, fiberglass, and composite panels — suitable for M3, M3.5, M4, M5, and M6 thread sizes.

Who Is This For
🔧 DIYers & WoodworkersPerfect for furniture assembly, cabinetry, and instrument building where a clean, rust-free finish matters. The self-tapping thread bites well into both softwoods and hardwoods without pre-drilling in most cases.
⚡ Electricians & Electronics BuildersBrass is non-magnetic and highly conductive — ideal for grounding lugs, electrical panels, switchgear, and PCB mounting where steel screws could cause interference or corrosion issues.
🚤 Marine & Outdoor ApplicationsNatural brass resists salt air and moisture without plating that can chip or peel. Use these for marine trim, outdoor fixtures, and covered exterior hardware where long-term appearance matters.
🎁 Decorative & Visible HardwareThe warm gold tone makes these screws a design element in their own right — great for musical instruments, decorative metalwork, antique restoration, and any project where the fastener is meant to be seen.
Frequently Asked Questions
Will brass screws rust like steel?
No. Brass is an alloy of copper and zinc and does not rust. It develops a natural patina over time, especially outdoors, but it will not red-rust or weaken like carbon steel. For indoor and covered outdoor use, brass holds up beautifully for decades.
Can I use these screws as wood screws?
Absolutely. The self-tapping thread bites well into both softwoods and hardwoods. For very dense hardwoods or when driving near the edge, a small pilot hole prevents splitting. The brass finish also makes them a favorite for furniture, cabinetry, and instrument building.
Are these screws conductive? Can I use them for electrical grounding?
Yes, brass is an excellent conductor and is widely used in electrical terminals, grounding bars, and switchgear. These screws are non-magnetic and provide a reliable connection — just ensure the mating surfaces are clean and tight.
Do I need to pre-drill a hole in sheet metal?
In thin sheet metal (up to about 1 mm), you can often drive them directly. For thicker metal or harder materials, a pilot hole about 80% of the thread diameter will reduce drive torque and give you the cleanest thread engagement.
Is the length measured including the head?
No. All listed lengths are the thread length only, measured from directly under the pan head to the tip. This makes it easy to match the screw to the material thickness you're fastening.
What packing quantities are available?
These screws are available in 2, 5, 10, 20, 50, and 100 piece packs. Smaller packs are ideal for one-off repairs or prototyping, while larger quantities offer better value for production runs or bulk projects.
How do brass self-tapping screws compare to stainless steel?
Brass is softer than stainless steel, making it easier to drive without stripping, and it's naturally non-magnetic and highly conductive. Stainless steel offers higher tensile strength for heavy-load applications. For electrical, decorative, and light-duty fastening, brass is typically the better choice.
