6063 Aluminium Phillips Pan Head Machine Screws DIN 7985 — M1.7 to M6 Metric

A general rule of thumb is to select a length that allows the screw to engage at least 1.5× the screw diameter into the receiving material. For example, an M3 screw (3mm diameter) should typically thread at least 4.5mm into the base material. If you are fastening two panels together, add the thickness of the top panel to the required thread engagement depth. Our variants range from 3mm (≈1/8") to 60mm (≈2-3/8") to cover most assembly needs.

6063 aluminium alloy generally has a tensile strength of approximately 145–186 MPa (21,000–27,000 psi) depending on temper. These screws are well-suited for light-to-medium duty fastening in electronics, enclosures, and structural panels where weight savings matter. For high-load structural applications, please contact us to confirm suitability.

6063 aluminium offers good natural corrosion resistance due to its stable oxide layer, making it generally suitable for outdoor environments with moderate moisture exposure. However, in highly corrosive environments such as direct saltwater immersion or coastal spray zones, additional protective coatings or stainless steel alternatives are typically recommended. Contact us to confirm suitability for your specific environment.

These screws conform to DIN 7985, which specifies metric coarse thread (ISO 68-1) pitch standards. M1.7 through M6 sizes use standard metric coarse pitches (e.g., M3 = 0.5mm pitch, M4 = 0.7mm pitch, M5 = 0.8mm pitch, M6 = 1.0mm pitch). They are compatible with standard metric nuts, inserts, and tapped holes following ISO metric thread specifications.

Yes. These aluminium Phillips pan head screws are commonly used with aluminium standoffs, brass inserts, nylon spacers, and PCB mounting hardware. The pan head profile provides a broad bearing surface that distributes clamping load evenly, making them well-suited for electronics enclosures and circuit board assemblies. Always verify thread pitch compatibility before assembly.

Phillips drive size generally corresponds to screw diameter: M1.7–M2 typically use a PH0 bit, M2.5–M3.5 typically use a PH1 bit, and M4–M6 typically use a PH2 bit. Using the correct bit size minimizes cam-out and protects the drive recess, especially important with aluminium which is softer than steel.

Depending on the size, quantities range from 10 to 500 pieces per order. For prototyping or small repairs, the smaller pack sizes (10–50 pcs) are generally sufficient. For production runs, assembly lines, or workshop stock, the larger packs (200–500 pcs) offer a lower per-unit cost. Select your size and quantity combination above before adding to cart.
