Standard steel pan head screws add unnecessary weight to assemblies where every gram counts — these aluminum alloy Phillips pan head machine screws deliver the same reliable clamping force at a fraction of the weight, with an anodized finish that resists corrosion over time.\u003c\/p\u003e\n\u003cp\u003eEach screw is machined from aluminum alloy with an anodized surface treatment for a clean, natural aluminum finish and enhanced oxidation resistance. Available in thread diameters from M3 to M8 and lengths from 6mm to 60mm (approximately 0.24\" to 2.36\"), with pack quantities of 10, 20, or 50 pieces depending on size. The pan head profile provides a larger bearing surface than a flat head, distributing clamping load across a wider area without the need for countersinking.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include assembling RC aircraft and drone frames (M3–M4), securing bicycle and cycling components (M4–M6), mounting electronics enclosures and camera equipment (M3–M5), and fastening lightweight machinery guards and aluminum extrusion panels (M5–M8) where a raised head profile is acceptable, and weight reduction is a design priority.\u003c\/p\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔩\u003c\/span\u003e Compatible with standard ISO metric tapped holes and threaded inserts.
