White Nylon Phillips Flat Head Machine Screws DIN 965 — Non-Conductive, Corrosion-Resistant Fasteners for Electronics and Plastic Assemblies
Anyone who has installed a PCB into a plastic enclosure, assembled a control panel, or built a food-processing fixture knows the problem with metal screws: they corrode, conduct electricity, and can cause galvanic damage to sensitive components. These white nylon Phillips flat head machine screws to DIN 965 eliminate all three concerns in one fastener. Made from polyamide PA66 nylon, they are electrically non-conductive, non-magnetic, and resistant to moisture, mild chemicals, and corrosion — making them the go-to choice for engineers, technicians, and DIY builders who need a reliable, clean-looking fastener that will not interfere with electronics or degrade in humid environments.
Available in six ISO metric thread diameters — M2.5, M3, M4, M5, M6, and M8 — with lengths ranging from 5mm (3/16") to 40mm (1-9/16") depending on the diameter selected. The countersunk flat head profile conforms to DIN 965, featuring a standardized 90-degree countersink angle that sits flush with or below the surface in any properly countersunk hole. Order in packs of 10, 50, 100, 500, or 1,000 pieces to match your project scale, from a single repair to a production run.
Typical applications include electronics and PCB enclosure assembly, control panel and instrument cover fastening, food-processing and laboratory equipment (where metal contamination must be avoided), 3D-printed and injection-molded plastic housings with heat-set inserts, and optical or photographic equipment where non-magnetic fasteners are required. The white color blends cleanly into light-colored enclosures and panels, eliminating the visual mismatch of dark metal hardware.
🔩 Thread Compatibility: ISO metric coarse thread — M2.5, M3, M4, M5, M6, M8. Compatible with standard metric nuts, heat-set inserts, and tapped holes per ISO 68-1. Not compatible with UNC/UNF inch-standard threads.
✅ Key Features of These White Nylon DIN 965 Phillips Flat Head Screws
- PA66 Nylon — Non-Conductive and Non-Magnetic — Electrically insulating and non-magnetic by nature, making these screws the correct choice for PCB mounting, electronics enclosures, and any assembly where metal fasteners would cause interference, short circuits, or galvanic corrosion.
- DIN 965 Countersunk Flat Head — 90-degree countersink angle per DIN 965 standard. Sits flush with or below the surface in a properly countersunk hole, delivering a clean, recessed finish in plastic panels, enclosure lids, and bracket assemblies.
- Phillips Cross Drive — Compatible with PH1 (M2.5–M3), PH2 (M4–M5), and PH3 (M6–M8) driver bits. Use the correct bit size and controlled torque to prevent cam-out on the nylon head — hand-driving or a low-torque power driver is recommended.
- Corrosion and Chemical Resistance — Resistant to moisture, mild acids, alkalis, and salt spray. Suitable for humid environments, light outdoor use, food-processing equipment, and laboratory fixtures where metal fasteners would corrode or contaminate.
-
↔Six Diameters, Multiple Lengths — M2.5 through M8 with lengths from 5mm (3/16") to 40mm (1-9/16") cover the majority of light-duty metric fastening needs in electronics, robotics, and plastic assemblies. Five pack-size options from 10 to 1,000 pieces.
- Heat-Set Insert Compatible — The flat head profile works seamlessly with brass and stainless heat-set inserts in 3D-printed and injection-molded plastic parts, delivering a flush, professional finish without additional countersinking tools.
⚠️ Application Note: Nylon screws are designed for light-duty, non-structural applications. They are not recommended for high-load, high-vibration, or elevated-temperature environments (above approx. 100 degrees C / 212 degrees F). If you are unsure whether nylon is appropriate for your application, contact us before ordering.

❓ Frequently Asked Questions
How do I choose the right length for my nylon flat head screw?
A general rule is to select a length equal to the thickness of the material being fastened plus the depth of the threaded hole or nut engagement. For thin plastic panels (3–6mm / 1/8"–1/4"), shorter lengths such as 5–8mm work well. For thicker enclosures or stacked layers, 12–25mm (1/2"–1") lengths are typically more appropriate. Always confirm thread engagement depth before ordering.
What material are these screws made from, and why does it matter?
These screws are made from white nylon (polyamide PA66). Nylon is lightweight, electrically non-conductive, non-magnetic, and resistant to corrosion, moisture, and mild chemicals. This makes it the preferred choice over metal fasteners in electronics assemblies, food-contact enclosures, and environments where rust or galvanic corrosion would be a concern.
What does DIN 965 mean, and why does it matter for compatibility?
DIN 965 is a German industrial standard specifying the geometry of countersunk (flat head) Phillips machine screws, including a standardized 90-degree countersink angle and consistent head-to-shank proportions. Screws made to DIN 965 are interchangeable with other DIN 965-compliant hardware, ensuring a flush fit in any properly countersunk hole designed to this standard.
Are nylon screws strong enough for my project?
Nylon screws are well-suited for light-duty, non-structural applications such as securing PCBs, plastic enclosure panels, control covers, and similar assemblies. They are generally not recommended for high-load, high-vibration, or structural applications where metal fasteners are required. If you are unsure whether nylon is appropriate for your load requirements, contact us to confirm before ordering.
Can I use these screws outdoors or in wet environments?
Nylon offers good resistance to moisture, mild chemicals, and salt spray, making these screws suitable for light outdoor and humid-environment use. However, prolonged UV exposure can degrade nylon over time, causing brittleness. For long-term outdoor applications with direct sun exposure, UV-stabilized nylon or stainless steel fasteners are generally a better choice.
What thread standard do these screws use, and are they compatible with my hardware?
These screws follow the ISO metric coarse thread standard (M2.5, M3, M4, M5, M6, M8) per ISO 68-1. They are compatible with standard metric nuts, brass or stainless heat-set inserts, and tapped holes machined to ISO metric tolerances. They are not compatible with UNC or UNF inch-standard threads.
What driver bit do I need, and how do I avoid stripping the head?
These screws use a Phillips (cross-head) drive. A PH1 bit is typically correct for M2.5 and M3; a PH2 bit for M4 and M5; and a PH3 bit for M6 and M8. Because nylon is softer than metal, using the correct bit size and applying steady, controlled torque is especially important to prevent cam-out and head damage. Hand-driving or using a low-torque setting on a power driver is recommended.
What is the maximum temperature these nylon screws can handle?
PA66 nylon generally has a continuous service temperature of approximately 80–100 degrees C (176–212 degrees F) and a short-term heat deflection temperature of around 200 degrees C (392 degrees F) under low load. For applications that regularly exceed these temperatures, alternative materials such as PEEK or metal fasteners should be considered.
