Brass Slotted Pan Head Machine Screws — Reliable Metric Fasteners from M2 to M10

Whether you\u2019re assembling electronics enclosures, repairing appliances, or building out a workshop jig, finding the right small metric screw in the right quantity shouldn\u2019t slow you down. Brass slotted pan head machine screws are a go-to choice for makers, repair technicians, and DIYers who need corrosion-resistant fasteners that won\u2019t strip easily and look clean in finished assemblies.

Each pack contains brass slotted pan head machine screws in your selected thread size and length. Thread sizes range from M2 (≈0.079\u2033) through M10 (≈0.394\u2033), with lengths from 3mm (≈1/8\u2033) up to 25mm (≈1\u2033) depending on the variant. Pack quantities range from 2 to 500 pieces, so you can grab just what you need for a one-off repair or stock up for ongoing production. Material is brass — an alloy known for its machinability, moderate corrosion resistance, and non-magnetic properties.

These screws are well-suited for electronics chassis assembly and PCB standoff mounting, furniture and cabinetry hardware where a clean pan head profile is needed, and plumbing fixture trim or instrument panel work where rust-free fasteners are a must. The slotted drive is universally accessible with a standard flat-blade screwdriver — no specialty bits required.

Compatibility: ISO metric thread standard (M-series). Compatible with standard metric nuts, threaded inserts, and tapped holes. Not compatible with UNC/UNF inch-thread fasteners.

✅ Key Features of These Brass Slotted Pan Head Machine Screws

  • 🧰Brass Construction — Naturally corrosion-resistant and non-magnetic, making these screws a reliable choice for electronics, plumbing trim, and humid-environment assemblies where steel would rust.
  • 🔍Wide Size Range — Available in M2 through M10 thread diameters and lengths from 3mm to 25mm, covering the most common metric machine screw sizes for DIY and light industrial use.
  • 🔧Slotted Pan Head Drive — The flat-topped pan head sits flush against surfaces without digging in, and the slotted drive works with any standard flat-blade screwdriver — no specialty tools needed.
  • 📦Flexible Pack Quantities — Choose from 2 to 500 pieces per order. Small packs suit single-project repairs; bulk packs of 250 or 500 reduce per-unit cost for production runs or workshop stock.
  • ISO Metric Thread Standard — Machined to standard M-series thread pitch, ensuring compatibility with metric nuts, brass inserts, and tapped holes across electronics, machinery, and furniture hardware.
  • 🛠Clean, Low-Profile Head — The pan head profile keeps a low silhouette ideal for panel mounting, enclosure assembly, and anywhere a countersunk or hex head would be too bulky or visually intrusive.

❓ Frequently Asked Questions

How do I choose the right thread size and length?

Match the thread diameter to your tapped hole or nut — M2 (≈0.079\u2033) for miniature electronics, up to M10 (≈0.394\u2033) for heavier structural work. For length, measure the material thickness you\u2019re fastening and add enough thread engagement: generally 1.5\u00d7 the screw diameter minimum. For example, an M3 screw through 4mm of material typically needs at least 5mm of thread engagement, so an M3 \u00d7 5mm or M3 \u00d7 8mm works well.

Are these screws strong enough for structural use?

Brass machine screws are generally suited for light-to-medium duty applications. Brass is softer than steel, so it\u2019s typically not recommended for high-load structural joints. It excels where corrosion resistance, electrical conductivity, or non-magnetic properties matter more than raw tensile strength.

Can I use these screws outdoors or in humid environments?

Yes. Brass offers good natural corrosion resistance and will not rust like carbon steel. It is generally suitable for indoor humid environments, marine-adjacent applications, and light outdoor use. For prolonged saltwater or highly acidic exposure, contact us to confirm suitability.

What thread standard do these screws follow — are they compatible with my nuts and inserts?

These screws follow the ISO metric thread standard (M-series), which is the international standard used worldwide. 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.

What screwdriver do I need for slotted pan head screws?

You need a flat-blade (slotted) screwdriver. Match the blade width to the screw head slot — typically a #1 or #2 flat-head driver for M2–M4, and a larger flat-head for M5–M10. Using an oversized blade risks damaging the slot or surrounding material.

How do I decide between buying 100 pcs vs. 500 pcs?

If you\u2019re working on a single project or prototyping, the 100-piece pack is typically sufficient. For production runs, workshop stock, or repeat repairs, the 250- or 500-piece bulk packs offer a lower per-unit cost. Check the variant pricing above to compare cost per screw across pack sizes.

Will brass screws react with aluminum or other metals (galvanic corrosion)?

Brass and aluminum can experience galvanic corrosion in wet environments due to their different electrochemical potentials. In dry or indoor settings this is generally not a concern. For outdoor or wet assemblies, consider using an anti-seize compound or an isolating washer between dissimilar metals.
