M4 M5 Nylon Phillips Pan Head Machine Screws with Hex Nuts and Flat Washers – White & Black

A general rule is to select a length that allows the screw to pass through the material being fastened and engage at least 1.5× the screw diameter into the receiving material. For example, if you're fastening a 6mm (1/4") panel, an M4 x 12mm screw typically works well. When in doubt, size up — you can always trim excess thread with a nylon-compatible cutter.

Nylon screws are generally suited for light-to-medium duty fastening applications. They are not intended for structural or high-torque assemblies. Typical tensile strength for nylon fasteners is around 50–70 MPa, though actual performance depends on the specific nylon grade. Contact us to confirm if you have specific load requirements.

Yes — nylon is inherently corrosion-resistant and will not rust, making these screws a solid choice for humid, wet, or mildly outdoor environments. However, prolonged UV exposure can degrade nylon over time. For long-term outdoor use, consider providing shading or UV protection where possible.

These screws follow the ISO metric thread standard — M4 with a 0.7mm pitch and M5 with a 0.8mm pitch. The included hex nuts are matched to the same metric thread. They are not compatible with UNC or UNF inch-standard threads. If you're unsure, check your existing hardware with a thread gauge before ordering.

Absolutely. Nylon is non-conductive and non-magnetic, making these screws an excellent choice for PCB mounting, electrical panel assembly, and any application where metal fasteners could cause short circuits or electromagnetic interference. They are widely used in electronics manufacturing and DIY electronics projects.

Each set includes matching nylon Phillips pan head machine screws, hex nuts, and flat washers — all in the same size and color (White or Black). Quantity options per set include 1, 5, 10, 20, 50, 100, 200, and 300 pieces, so you can order exactly what your project requires.

These screws use a Phillips (cross) drive head. For M4 screws, a PH1 or PH2 bit is typically appropriate. For M5 screws, a PH2 bit is generally recommended. Always use a properly sized bit to avoid stripping the nylon head — nylon is softer than metal and can be damaged by an oversized or worn bit.
