Whether you're assembling electronics enclosures, fabricating metal brackets, or building out equipment racks, finding the right metric machine screw in the right finish can be frustrating. Mismatched threads, rust-prone hardware, and inconsistent head profiles slow down your work and compromise the final result. These M5 M6 black stainless steel Phillips pan head machine screws are designed for builders, fabricators, technicians, and DIYers who need dependable metric fasteners that look as good as they perform.
Each screw features a round pan head profile with a Phillips cross drive recess, machined to ISO metric thread standards. M5 screws are available in lengths from 5mm (≈3/16") to 100mm (≈3-15/16"), and M6 screws range from 6mm (≈1/4") to 100mm (≈3-15/16"). The black stainless steel finish combines the corrosion resistance of stainless steel with a sleek, low-visibility appearance. Sold in packs of 10, 20, 100, 500, or 1000 pieces — select the size and quantity that fits your project.
These black Phillips pan head machine screws are a go-to choice for electronics panel assembly, server rack mounting, machinery guard installation, and precision equipment fabrication. They're also widely used in furniture hardware, automotive interior trim, and architectural metalwork where a clean black fastener finish is required.

A general rule of thumb is to select a screw length approximately 2–3 times the screw diameter. For M5 screws, lengths typically range from 5mm (≈3/16") to 100mm (≈3-15/16"); for M6, from 6mm (≈1/4") to 100mm (≈3-15/16"). Measure your material thickness and ensure at least 1.5× the screw diameter of thread engagement into the receiving material for a secure hold.
Stainless steel machine screws generally offer good tensile and shear strength suitable for light-to-medium duty fastening applications. The exact load capacity depends on the specific stainless steel grade and the material being fastened. Contact us to confirm the grade if your application has strict load or certification requirements.
Yes. Stainless steel provides inherent corrosion resistance, making these screws generally suitable for outdoor, humid, or mildly corrosive environments. The black finish adds an additional aesthetic layer. For highly aggressive environments such as saltwater exposure or strong chemical contact, confirm the specific stainless grade before use.
These screws use the ISO metric thread standard. M5 has a standard pitch of 0.8mm and M6 has a standard pitch of 1.0mm. They are compatible with standard metric nuts, threaded inserts, and tapped holes following ISO 68-1 specifications — the same standard used across machinery, electronics, and automotive applications worldwide.
These screws feature a Phillips (cross) drive recess. For M5 screws, a PH2 Phillips screwdriver or power bit is typically the correct fit. For M6 screws, a PH2 or PH3 bit is generally appropriate depending on the head size. Always use a properly sized driver to avoid cam-out and head damage, especially on stainless steel fasteners.
Yes. M5 and M6 pan head machine screws are commonly used in electronics enclosures, server racks, precision equipment panels, and machinery guards. The low-profile pan head sits close to the surface without excessive protrusion, making it well-suited for assemblies where clearance and a clean appearance matter.
These screws are available in packs of 10, 20, 100, 500, and 1000 pieces depending on the size selected. Larger quantity packs offer a significantly lower per-unit cost. The 500 or 1000-piece options are ideal for production runs, contractors, or keeping workshop stock on hand. Smaller packs of 10 or 20 are great for one-off repairs or prototyping.
M5 refers to a 5mm nominal thread diameter and M6 refers to a 6mm nominal thread diameter. Check the thread size of your existing hardware, tapped hole, or nut to determine which diameter you need. M5 is commonly used in lighter assemblies and electronics, while M6 is more typical in structural, mechanical, and heavier-duty applications. When in doubt, measure the thread diameter with calipers or a thread gauge.
