Nylon Plastic Hex Nut M2–M12 — Black & White Metric Insulated Hexagon Nut

Nylon hex nuts are the go-to fastener wherever electrical insulation, corrosion resistance, or weight reduction is required. Available in metric sizes from M2 to M12 in both black and white, these PA66 nylon nuts are non-conductive, non-magnetic, and immune to rust — making them ideal for PCB standoff assemblies, electronics enclosures, marine hardware, and chemical-exposure environments where metal nuts would corrode or create short-circuit risks.

Why Choose Nylon Hex Nuts?

Electrical insulation — Non-conductive PA66 prevents short circuits in PCB assemblies, electronics enclosures, and electrical panel wiring
Corrosion-free — Nylon does not rust, oxidize, or react with mild acids and alkalis; ideal for marine, outdoor, and chemical environments
Lightweight — Approximately 7× lighter than steel nuts of the same size; reduces weight in weight-sensitive assemblies
Non-magnetic — Safe for use near sensitive magnetic sensors, MRI-adjacent equipment, and RF circuits
Self-damping — Nylon’s inherent flexibility provides mild vibration resistance without a separate lock washer

Typical Applications

PCB standoff and spacer assemblies (M2, M2.5, M3)
Electronics enclosure panel mounting
Marine and outdoor hardware (corrosion-free)
Aquarium and hydroponic system fittings
Chemical processing equipment fasteners
RC model and drone frame assembly (weight reduction)
Electrical panel insulated fasteners

Frequently Asked Questions

Q: What is the torque limit for nylon hex nuts?

Nylon nuts have significantly lower torque limits than steel. For M3 nylon nuts, maximum torque is approximately 0.5–0.8 N·m. Over-tightening will strip the threads or crack the nut. Tighten finger-tight plus a quarter turn with a wrench for most applications.

Q: Are these UV-resistant?

Standard PA66 nylon has moderate UV resistance. For long-term outdoor exposure in direct sunlight, consider UV-stabilized nylon variants or protect with a UV-resistant coating.
