Nylon Hex Nuts — commonly referred to as nylon plastic nuts or PA66 hex nuts — are injection-molded fasteners produced from polyamide 66 resin. Thread sizes from M3 to M20 are available. Metric coarse thread per ISO 724 is standard. Fine thread and UNC/UNF threads are available on request. Continuous operating temperature ranges from -30 °C to 110 °C.

Applications

  • Chemical processing equipment and tank fittings
  • Electrical enclosures and terminal assemblies
  • Food machinery (FDA-compliant grades available)
  • Automotive sensor brackets and interior trim
  • Medical device housings and instrumentation
  • Water treatment and marine hardware

Key Performance Data

  • Corrosion‑free in salt spray (ASTM B117, 500 hours). No rust or discoloration.
  • Dielectric strength 25 kV/mm enables use as electrical isolation fasteners.
  • Coefficient of friction 0.20–0.25 against steel, dry. No galling on stainless steel studs.
  • Weight 85% lower than steel nuts of identical size — M8 nylon nut weighs approx. 0.7 g versus 5.5 g for steel.
  • Non‑magnetic. Suitable for MRI and sensor applications.

Certifications & Compliance

  • ISO 9001:2015 — certified quality management system.
  • RoHS (Directive 2011/65/EU) — compliant.
  • FDA 21 CFR 177.1500 — compliant grades available (natural PA66 without colorants).
  • Third‑party test reports for tensile, dielectric strength, and salt spray available upon request.
