Metal screws conduct electricity — and in electronics, PCB assemblies, and medical equipment, that’s a problem. A short circuit caused by a conductive fastener can damage components, void warranties, or create safety hazards. This 150-piece nylon fastener kit gives engineers, hobbyists, and repair technicians a complete set of electrically insulating screws, nuts, and washers in five metric sizes, ready to use straight out of the box.
The kit includes M2, M2.5, M3, M4, and M5 nylon Phillips pan head screws in two lengths per size, plus matching hex nuts and flat washers — 30 pieces per size group, 150 pieces total. All fasteners are black nylon with a lens (pan) head and cross recess (Phillips) drive. Item weight: 52 g. Case dimensions: 16 × 13 × 1.6 cm with removable dividers and a locking cover slot.
Ideal for electronics and PCB mounting, communication and networking equipment assembly, electroplating and chemical processing environments, medical device fabrication, office equipment repair, and any application where electrical insulation, corrosion resistance, and lightweight fastening are required.

Mount PCBs, standoffs, and panel components without risk of short circuits — nylon’s non-conductive properties make it the standard choice for electronics enclosure fastening.
Non-metallic fasteners are required in many medical device assemblies to avoid interference with imaging equipment and to meet biocompatibility requirements in patient-contact environments.
Nylon resists mild acids, alkalis, and plating solutions where metal fasteners would corrode rapidly — ideal for jigs, fixtures, and equipment used in wet chemical processes.
Building RC models, 3D printer enclosures, or custom electronics projects? Nylon screws are lightweight, easy to cut to length, and won’t damage delicate plastic housings during assembly.

The kit includes M2, M2.5, M3, M4, and M5 sizes — each with two screw lengths (5 pcs each), 10 hex nuts, and 10 flat washers, totaling 30 pieces per size group and 150 pieces overall. All stored in a compartmentalized case with removable dividers.
Yes. Nylon (PA66) is a non-conductive polymer with excellent electrical insulation properties. These screws will not conduct electricity, making them safe for use in PCB assemblies, electronics enclosures, and any application where metal fasteners could cause short circuits.
Yes. Nylon resists moisture, mild acids, alkalis, and many common solvents. It is widely used in electroplating jigs, chemical processing equipment, and outdoor electronics enclosures where metal fasteners would corrode. For strong acids or organic solvents, verify chemical compatibility before use.
Nylon screws are significantly weaker than steel or aluminum in tensile and shear strength. They are designed for light-duty fastening in electronics, panels, and non-structural assemblies — not for high-torque or load-bearing applications. Do not over-tighten; nylon threads strip more easily than metal.
Use a PH0 or PH1 screwdriver for M2 and M2.5 screws, and a PH1 or PH2 for M3–M5 screws. Always use a properly fitting screwdriver to avoid cam-out and stripping the nylon recess, which is softer than metal.
Nylon has good UV and moisture resistance for short-term outdoor exposure, but prolonged UV exposure can cause gradual degradation. For long-term outdoor applications, consider UV-stabilized nylon or stainless steel fasteners instead.
Yes. Nylon can be cut with a sharp hobby knife, flush cutters, or a fine-tooth saw. Score and snap works for smaller diameters (M2–M3). After cutting, clean up the thread end with a file or deburring tool to ensure smooth engagement with the nut.
