Whether you're assembling an electronics enclosure, building a furniture frame, or tackling a precision DIY repair, finding the right fastener in the right size shouldn't slow you down. These brass Phillips pan head machine screws are designed for makers, hobbyists, and tradespeople who need a dependable, corrosion-resistant fastener available in a wide range of metric sizes.
Each pack contains brass Phillips pan head machine screws in your chosen size and quantity. Diameter options span M3, M4, M5, M6, and M8, with lengths ranging from 4mm (≈5/32") to 60mm (≈2-3/8"). Pack sizes range from 1 to 100 pieces, so you can order exactly what you need — no waste, no shortage. The pan head profile provides a broad bearing surface, and the Phillips drive is compatible with standard PH1 and PH2 bits.
These brass machine screws for electronics assembly are a go-to choice for PCB enclosures, instrument panels, and light-duty mechanical assemblies. They're equally at home in woodworking jigs, model making, and appliance repair — anywhere a metric Phillips pan head screw with a clean finish is required.

A general rule of thumb is to choose a screw length that is 2–3 times the thickness of the material being fastened. For example, if you're joining two 5mm (≈3/16") panels, a 10–15mm (≈3/8"–9/16") screw is typically appropriate. Always account for the nut and washer stack height when calculating total grip length.
These screws follow the ISO metric thread standard (M3, M4, M5, M6, M8), which is the most widely used standard globally. They are compatible with standard metric hex nuts and washers of the same diameter. In most cases, any metric nut labeled M3, M4, M5, M6, or M8 will thread correctly onto these screws.
Brass offers good natural corrosion resistance and is generally suitable for mildly humid or sheltered outdoor environments. For prolonged exposure to saltwater, rain, or harsh weather, a stainless steel alternative is typically recommended. Brass is an excellent choice for indoor electronics, plumbing fixtures, and decorative hardware.
Brass generally has a tensile strength of around 300–500 MPa depending on the specific alloy grade. Load capacity also depends on screw diameter, length, and the materials being joined. For structural or high-load applications, we recommend consulting an engineer or referring to the specific alloy datasheet. These screws are well-suited for light-to-medium duty fastening tasks.
This listing includes brass Phillips pan head machine screws. Whether hex nuts and washers are included depends on the specific variant selected. Please review the variant title carefully or contact us before ordering to confirm exactly what is included in your chosen pack size.
These screws use a Phillips (cross-head) drive. For M3 and M4 sizes, a PH1 bit is typically used. For M5, M6, and M8 sizes, a PH2 bit is generally recommended. Both manual screwdrivers and power drills with Phillips bits are compatible. Using the correct bit size helps prevent cam-out and head damage.
Yes — brass is non-magnetic and has lower electrical conductivity than steel, making it a common choice for electronics enclosures, PCB standoffs, and instrument panels where magnetic interference must be minimized. The M3 size is especially popular for electronics assembly and computer hardware mounting.
The size format is diameter × length. For example, M4×16 means a 4mm diameter screw that is 16mm (≈5/8") long. The "M" prefix indicates ISO metric thread. Always verify both dimensions before ordering to ensure the screw fits your application.
