When a stripped screw or mismatched fastener stalls your project, every minute counts. Whether you're a maker assembling electronics enclosures, a technician maintaining equipment panels, or a DIYer building furniture frames, having the right metric machine screw on hand is non-negotiable. These Phillips pan head screws are engineered for precision fit and reliable clamping force across a wide range of applications.
Each screw is machined from carbon steel and finished with a black oxide coating, delivering a clean matte appearance alongside moderate corrosion resistance. Available in M3, M4, M5, and M6 thread diameters with shank lengths ranging from 3mm to 50mm (0.12" to 1.97"), these screws cover the most common metric fastener needs in a single listing. Pack sizes from 5 to 1000 pieces let you order exactly what your project demands.
Ideal for electronics assembly, 3D printer frames, RC car chassis, aluminum extrusion builds, cabinetry hardware, and general mechanical maintenance. The pan head profile distributes clamping load evenly across the surface, making it a go-to choice for thin sheet metal, plastic panels, and soft substrates where countersinking isn't practical.

These screws are available in M3, M4, M5, and M6 metric thread sizes. Lengths vary by diameter — M3 goes from 3mm to 40mm, M4 from 4mm to 40mm, M5 from 6mm to 40mm, and M6 from 8mm to 50mm.
These screws are made from carbon steel with a black oxide surface treatment. The finish provides a uniform matte black appearance and moderate corrosion resistance, suitable for indoor and semi-protected applications.
The black oxide finish offers limited corrosion resistance. For outdoor or high-humidity environments, we recommend applying a light oil coating or selecting stainless steel alternatives for long-term performance.
Use a PH1 bit for M3 screws, a PH2 bit for M4 and M5, and a PH2 or PH3 bit for M6, depending on torque requirements. Always use a properly sized bit to avoid cam-out and head damage.
The listed length is the shank length excluding the head. As a general guideline, the screw should engage at least 1.5× the thread diameter into the receiving material — for example, an M4 screw should typically engage at least 6mm of thread for a secure hold.
Yes. These screws follow ISO metric thread specifications and are compatible with standard metric hex nuts, nylon lock nuts, and heat-set or press-fit threaded inserts of the corresponding size.
Pan head screws are commonly used in electronics enclosures, 3D printer frames, RC car chassis, aluminum extrusion assemblies, cabinetry hardware, and general mechanical maintenance where a low-profile, wide-bearing head is needed without countersinking.
