M6 M8 M10 Phillips Pan Head Machine Screws — Reliable Fastening in 304 A2 Stainless Steel
When a loose bolt or corroded fastener derails your project, the right screw makes all the difference. Whether you're a DIYer assembling furniture, a hobbyist building a CNC frame, or a small shop maintaining equipment, finding metric machine screws that hold up over time — without rusting or stripping — is a constant challenge. These Phillips pan head machine screws are made from 304 A2 stainless steel, giving you a fastener that resists corrosion and maintains its finish through repeated use.
Each set includes pan head machine screws in your chosen diameter (M6, M8, or M10) and thread length, available in pack sizes of 1, 2, 5, 10, 50, or 100 pieces. The M6 thread diameter is 6mm (≈0.24"), M8 is 8mm (≈0.31"), and M10 is 10mm (≈0.39"). Thread lengths range from 6mm (≈1/4") up to 100mm (≈3-15/16"), covering a wide range of fastening depths. All screws feature a Phillips (cross) drive recess and a low-profile pan head for flush or near-flush installations.
These stainless machine screws are well-suited for electronics enclosure assembly, machinery maintenance, bracket and panel fastening, outdoor furniture construction, and light automotive or marine accessory installation — anywhere a metric Phillips pan head screw with corrosion resistance is needed.
🔩 Compatibility: ISO metric coarse thread (M6 × 1.0, M8 × 1.25, M10 × 1.5). Compatible with standard metric nuts, threaded inserts, and tapped holes per ISO 68-1. Not compatible with UNC/UNF inch-standard fasteners.
⚠️ Confirm your thread size before ordering. M6, M8, and M10 are not interchangeable. If unsure, use a thread gauge or measure your existing nut/tapped hole before selecting a variant.
✅ Key Features of These 304 Stainless Steel Phillips Pan Head Machine Screws
-
🛡️304 A2 Stainless Steel Construction — Resists rust, oxidation, and staining in outdoor, humid, and mildly corrosive environments, making these screws a dependable choice for long-term installations.
-
🔘Pan Head Profile — The low, rounded head distributes clamping load evenly and sits flush or near-flush against the workpiece surface, reducing snagging and providing a clean finished look.
-
✚Phillips Cross Drive — Compatible with standard #2 and #3 Phillips bits and drivers, making installation straightforward with tools most workshops already have on hand.
-
📏Wide Size Range — Available in M6, M8, and M10 diameters with thread lengths from 6mm (≈1/4") to 100mm (≈3-15/16"), covering the most common metric machine screw applications in one listing.
-
📦Flexible Pack Quantities — Order as few as 1–2 pieces for a quick repair or up to 100 pieces for production runs and bulk stocking, with per-unit cost decreasing at higher quantities.
-
⚙️ISO Metric Coarse Thread — Standard thread pitch (M6×1.0, M8×1.25, M10×1.5) ensures compatibility with off-the-shelf metric nuts, threaded inserts, and tapped holes without special tooling.

❓ Frequently Asked Questions
How do I choose the right thread length for my project?
A general rule: the screw length should be at least 1.5× the diameter of the screw for a secure hold. For example, an M6 screw typically needs at least 10mm of thread engagement. If you're fastening two panels, measure the combined thickness and add 5–10mm for nut clearance. Available lengths range from 6mm (≈1/4") to 100mm (≈3-15/16").
What load can these machine screws handle?
304 stainless steel generally has a tensile strength of approximately 515 MPa (75,000 psi). Actual load capacity depends on thread engagement depth, base material, and installation torque. For structural or safety-critical applications, consult an engineer to confirm suitability.
Are these screws suitable for outdoor or marine use?
304 stainless steel (A2) offers good corrosion resistance for most outdoor environments including rain, humidity, and mild coastal exposure. For highly aggressive marine or saltwater environments, 316 stainless steel is generally recommended. These screws are suitable for most outdoor DIY, garden, and light marine applications.
What thread standard do these screws use — are they compatible with my nuts?
These screws use standard ISO metric coarse thread (M6, M8, M10). They are compatible with standard metric nuts, threaded inserts, and tapped holes following ISO 68-1 specifications. They are not compatible with UNC/UNF inch-standard fasteners.
Which diameter should I choose — M6, M8, or M10?
M6 (6mm diameter) is typically used for light-duty assemblies, electronics enclosures, and furniture. M8 (8mm diameter) suits medium-duty applications like machinery guards, brackets, and automotive accessories. M10 (10mm diameter) is generally chosen for heavier structural connections. Match the size to your existing tapped holes or nuts.
What screwdriver or bit do I need to drive these screws?
These screws have a Phillips (cross) drive head. For M6 and M8, a #2 Phillips bit is typically used. For M10, a #3 Phillips bit is generally recommended. Using the correct bit size reduces cam-out and protects the head finish.
Can I use these screws with aluminum, plastic, or wood?
These are machine screws designed for use with pre-tapped holes, threaded inserts, or nuts — not for self-tapping into wood or plastic. They work well with aluminum, steel, and other metals that have been tapped to the appropriate metric thread. For wood or plastic, a self-tapping or wood screw would be more appropriate.
