White Nylon Plastic Insulated Screw — M2 / M2.5 / M3 / M4 Phillips Pan Head (50PCS)
When electrical isolation is critical, metal screws are a liability. These white nylon plastic machine screws provide the mechanical fastening you need without any risk of short circuits, galvanic corrosion, or RF interference. Manufactured to GB818 standard with a Phillips pan head drive, they’re the go-to choice for PCB mounting, electronics enclosures, sensor housings, and any application where non-conductive fasteners are required.

Why Choose Nylon Screws?
- ✅ Electrically non-conductive — eliminates short circuit risk when mounting PCBs and electronic components
- ✅ Lightweight — nylon is significantly lighter than steel, reducing overall assembly weight
- ✅ Corrosion-proof — immune to rust and galvanic corrosion in humid or chemical environments
- ✅ RF-transparent — does not interfere with antenna or RF circuit performance
- ✅ Chemical resistance — resistant to most common solvents, oils, and cleaning agents
- ✅ White color — clean, professional appearance for visible assemblies
- ✅ GB818 standard — consistent dimensions for reliable fit with standard M2–M4 nuts and threaded inserts
Common Applications
- PCB standoff and mounting screws in electronics enclosures
- Arduino, Raspberry Pi, and microcontroller board mounting
- Sensor housing and module assembly
- Electrical panel insulation fasteners
- 3D printer frame and component assembly
- RC model and drone frame assembly
- Medical device and laboratory equipment assembly
- Antenna and RF module mounting (non-metallic requirement)
Frequently Asked Questions
Q: What is the maximum torque for nylon screws?
A: Nylon screws have lower tensile strength than metal. For M3 nylon screws, maximum recommended torque is approximately 0.3–0.5 N·m. Do not overtighten — hand-tight plus a quarter turn is sufficient for most PCB mounting applications.
Q: Are these compatible with standard metal nuts?
A: Yes. GB818 M2–M4 nylon screws are dimensionally compatible with standard metric nuts and threaded inserts of the same size.
Q: Can these be used outdoors?
A: Nylon (PA66) has good UV and weather resistance for short-term outdoor use. For long-term outdoor applications, consider UV-stabilized nylon variants.
