PVC Hexagon nut Overview
PVC Hexagon Nut is a specialized non-metallic fastener prized for its exceptional chemical resistance, electrical insulation properties, and lightweight construction。PVC Hexagon Nut maintains the standard six-sided profile of any conventional hex nut, allowing it to be driven by a standard wrench or hex nut driver
PVC hex nuts follow common hex nut sizes, including:
m8 hex nut
metric hex nuts
3/8 hex nut
Standard imperial and metric series
They also conform to standard hex nut dimensions, hex nut diameter, and hex nut height guidelines similar to traditional hex nuts.
Product Parameters
PVC Hexagon Nuts typically follow established metric standards for regular hexagon nuts, such as ISO 4032, ensuring compatibility with standard bolts and threaded rods.
| Nominal Size (Bolt d) | Thread Pitch (P) | Across Flats (s) | Nut Height (m) |
| M4 | 0.7 mm | 7.0 mm | 3.2 mm |
| M5 | 0.8 mm | 8.0 mm | 4.7 mm |
| M6 | 1.0 mm | 10.0 mm | 5.2 mm |
| M8 | 1.25 mm | 13.0 mm | 6.4 mm |
| M10 | 1.5 mm | 16.0 mm | 8.0 mm |
| M12 | 1.75 mm | 18.0 mm | 10.0 mm |
| M16 | 2.0 mm | 24.0 mm | 13.0 mm |
Key Features
The essential features of the PVC Hexagon Nut are defined by the unique properties of Polyvinyl Chloride:
Exceptional Chemical Resistance: PVC is impervious to a vast array of corrosive agents, including most inorganic acids, alkalis, salts, and alcohol solutions. This is the primary advantage over all metal hex nuts.
Electrical Insulation: PVC is a highly effective dielectric, making it ideal for creating electrical isolation between conductors and preventing galvanic corrosion.
Dimensional Compliance: Though plastic, PVC hex nuts adhere to standard dimensional specifications (hex nut dimensions, hex nut height, hex nut diameter) for compatibility with standard bolt hex nut assemblies.
Lightweight: Significant weight reduction compared to metal nuts, a benefit in weight-sensitive assemblies.
Cost-Effective: Generally an inexpensive material, suitable for large-volume industrial applications.
Key Polyvinyl Chloride (PVC) Properties
Applications
The PVC Hexagon Nut is critical in environments where material integrity is challenged by external factors:
Chemical Processing and Plating: Used in the construction of acid tanks, fume hoods, ventilation systems, and plating racks where metal fasteners would quickly degrade.
Water Treatment and Plumbing: Employed in pipes, pumps, and valves handling corrosive water or chemical additives (nylon hex nut or PVC is preferred here over metal).
Electrical Equipment: Used to secure wire terminals, battery components, and PCBs, acting as an insulating barrier to prevent short circuits and electrolysis.
Outdoor and Marine Environments: Provides reliable fastening without the risk of rust, even when exposed to salt spray and moisture, offering a solution superior to non-stainless steel options.
Aesthetics and Safety: Can be used with plastic hex nut caps for a smooth, finished, and safe appearance.
Advantages
- Excellent Corrosion Resistance：Better than steel in wet, chemical, or salt-exposed environments.
- Lightweight：Much lighter than stainless steel hex nuts, beneficial for portable systems.
- Electrical Insulation：Completely non-conductive; ideal for electrical hardware.
- Economical：PVC nuts cost less than metal equivalents and nylon alternatives.
- Non-Metallic and Non-Magnetic：No galvanic corrosion, no magnetic interference.
Packaging & Delivery
