The 3mm x 7mm x 5mm Nylon Spacer is a compact non-metallic spacer used for PCB mounting, electronics assemblies, 3D printer parts, panel spacing, brackets, small fixtures, jigs, robotics projects, and custom DIY builds. This 10-piece pack is useful when you need lightweight spacing hardware that provides a clean gap between parts without using a metal spacer.
With a 3mm inside diameter, 7mm outside diameter, and 5mm height, these nylon spacers are well suited for compact assemblies using compatible M3 screws, small bolts, rods, or mounting hardware. They can help separate circuit boards from mounting plates, lift panels off a surface, isolate parts from direct contact, support electronics, or create a consistent 5mm standoff in a finished assembly.
Nylon spacers are commonly used in electronics because they are lightweight, non-metallic, and useful where electrical isolation is preferred. The 3mm x 7mm x 5mm Nylon Spacer can be used between PCBs, control boards, mounting plates, enclosure walls, sensor brackets, and electronics panels. The 5mm height provides a compact gap for airflow, clearance, wire routing, or board protection.
This spacer set is also useful for 3D printer repairs, printer upgrades, laser-cut panels, acrylic enclosures, small brackets, robotics mechanisms, display stands, signs, models, and light-duty mechanical assemblies. Nylon spacers are a practical choice when you need lightweight spacing without adding much weight to the project.
Nylon provides a clean, simple spacer material for many indoor hardware applications. It is useful where corrosion resistance, electrical insulation, light weight, and non-marring contact are helpful. Because nylon is softer than metal, it can also reduce the risk of scratching delicate surfaces compared with aluminum or steel spacers.
Before installation, confirm that the spacer dimensions match your hardware and project design. The 3mm inside diameter is intended for compatible M3-style hardware, but tolerances can vary depending on the screw, spacer, and application. Always test fit before final tightening, especially when working with electronics, printed parts, acrylic panels, or thin materials.
For related hardware, browse the Fasteners category. These spacers can be paired with Metric Socket Head Screws, nuts, washers, panels, brackets, 3D printer hardware, electronics mounts, and other fabrication components from dnb3D.
Nylon is widely used in spacer and standoff applications because it is lightweight, non-conductive, and useful in many electronics and mechanical assemblies. For general engineering context on nylon material properties, see this MatWeb material property reference.
Every order is hand-inspected and precision-shipped from dnb3D in Marathon, Ontario. Whether you are mounting electronics, spacing a panel, repairing a 3D printer, building a small fixture, or stocking workshop hardware, this 3mm x 7mm x 5mm Nylon Spacer 10pcs set provides a simple and reliable spacing solution.
The 3mm x 7mm x 5mm Nylon Spacer 10pcs set is used for PCB mounting, electronics spacing, standoff support, panel separation, and small mechanical assemblies.

Before installation, confirm that the 3mm x 7mm x 5mm Nylon Spacer matches your design. Check the inside diameter, outside diameter, and height before final assembly. The spacer should fit the selected M3 screw, bolt, rod, or mounting hardware without forcing.
When using this spacer between two parts, make sure the screw or bolt is long enough to pass through the spacer and still provide proper thread engagement. A fastener that is too short may not hold securely, while a fastener that is too long may bottom out, interfere with nearby parts, or damage electronics.
Use light, controlled tightening. Nylon spacers are useful for electronics and light-duty assemblies, but excessive force can deform the spacer, crack acrylic, crush 3D printed parts, or damage circuit boards. Tighten only enough to secure the assembly.
If the spacer is being used against acrylic, thin plastic, wood, printed parts, or delicate electronics, a washer may help spread the load and protect the surface. This is especially useful when the assembly will be adjusted, removed, or re-tightened later.
Spacers are often used to create clean, even gaps. Before final tightening, make sure all spacers are seated evenly and that the board, panel, bracket, or mounted part is square. Uneven tightening can cause twisting, stress, or cracked materials.
Nylon is suitable for many indoor hardware and electronics applications, but it should not be used where the spacer will be exposed to excessive heat, open flame, or hot components beyond the material’s safe working range. Keep spacers away from heaters, hotends, cutting areas, and high-temperature machine zones unless the application has been verified.
Keep the spacer free from chips, dust, adhesive, paint buildup, oil, and abrasive debris. If used as visible hardware on a finished project, wipe with a soft cloth during final assembly.
