Whether you're assembling electronics enclosures, securing sheet metal panels, or building out a DIY project that needs to hold up over time, finding the right metric machine screw in the right quantity shouldn't be a hassle. These M5 M6 Phillips pan head machine screws are designed for makers, maintenance professionals, and home improvement enthusiasts who need a dependable stainless steel fastener without hunting through multiple suppliers.
Each listing covers M5 (5mm thread diameter) or M6 (6mm thread diameter) screws in A2 grade 304 stainless steel, with a pan/round head profile and Phillips drive. Lengths range from 6mm (≈1/4") to 100mm (≈3-15/16"), and packing quantities run from 2 to 100 pieces per order — so you can grab just what you need for a repair or stock up for a larger build. Thread pitch follows the standard ISO metric coarse specification: M5 at 0.8mm pitch and M6 at 1.0mm pitch.
These stainless Phillips pan head screws are a go-to choice for electronics cabinet assembly, HVAC ductwork fastening, appliance repair, and general fabrication work where corrosion resistance and a low-profile head are both priorities. The rounded pan head sits flush against surfaces without sharp edges, making it well-suited for applications where contact with hands or soft materials is expected.

A general guideline is to select a length equal to the thickness of the material being fastened plus at least 1.5× the thread diameter for engagement in the receiving material. For example, when fastening a 5mm panel into a threaded insert using M5 screws, a 10mm (≈3/8") or 12mm (≈1/2") length is typically appropriate. Always verify the thread engagement depth in your specific application before ordering.
A2 grade 304 stainless steel machine screws generally have a tensile strength of around 500–700 MPa, depending on the manufacturing process and exact alloy composition. They are suitable for most light-to-medium duty fastening applications. For high-load structural connections, consult an engineer and verify the specific grade rating of the fastener.
A2 304 stainless steel provides good corrosion resistance and is generally suitable for outdoor use in most climates, including light exposure to rain and humidity. However, in coastal or highly saline environments, prolonged exposure may cause surface staining over time. For harsh marine conditions, A4 316 stainless steel is typically the better choice.
Yes. These are ISO metric coarse thread machine screws. M5 uses a 0.8mm pitch and M6 uses a 1.0mm pitch — the most common configurations for general fastening. They are compatible with standard metric nuts, washers, threaded inserts, and tapped holes that follow the same ISO metric specification.
For M5 pan head screws, a PH2 (Phillips #2) bit is typically the correct fit. For M6 pan head screws, a PH2 or PH3 bit is generally appropriate depending on the exact head dimensions. Always use a properly sized bit to avoid cam-out and damage to the screw head, especially when using a power driver.
Yes. These machine screws are compatible with M5 or M6 metric nuts, flat washers, lock washers, and threaded inserts that follow ISO metric standards. Always confirm the thread pitch matches your hardware — M5 at 0.8mm and M6 at 1.0mm — before assembly.
M5 (5mm diameter) is lighter and well-suited for thinner panels, electronics enclosures, and lighter-duty assemblies. M6 (6mm diameter) offers more clamping force and is generally preferred for structural connections, machinery, and applications requiring higher torque. Check your existing threaded holes or hardware specifications to confirm which size fits your application.
