PPS/NT ｜ PPS Hexagon Nut for High-Temperature and Engineering Environments
🌟 Key Takeaways
- PPS/NT is a hexagon nut manufactured from Polyphenylene Sulfide (PPS)
- Supports continuous operating temperatures up to 200°C (392°F) and complies with UL94 V-0
- Nut dimensions (B × H) are optimized for the mechanical properties of PPS to ensure strength and tightening stability
- Electrically insulating, non-magnetic, and chemical-resistant, suitable for industrial and electronic applications
ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー
In machinery, electrical equipment, and industrial modules, nuts do more than simply secure screws.
They are critical components that must withstand compressive loads, tensile forces, and sustained high temperatures.
When metal nuts are used, issues such as corrosion or unwanted electrical conductivity may arise.
PPS/NT was therefore developed as an alternative for applications requiring mechanical stability, electrical insulation, and long-term durability.
Although a nut is a small component, improper selection can significantly affect overall system lifespan.
PPS/NT enhances fastening reliability in environments where metal fasteners cannot sufficiently meet safety or durability requirements.
PPS/NT is a hexagon nut for metric thread systems, designed for use with PPS screws and compatible with metal screws when applied within appropriate load limits.
The hexagonal shape enables uniform torque transmission and reduces tool slippage.
The PPS material provides high mechanical strength, low moisture absorption, and excellent dimensional stability at elevated temperatures, making PPS/NT suitable for repeated tightening and long-term use.
🔷 Thread Pitch (Metric Coarse)
PPS/NT uses standard metric coarse threads for compatibility with common screw systems.
- M2 = 0.40 mm
- M2.5 / M2.6 = 0.45 mm
- M3 = 0.50 mm
- M4 = 0.70 mm
- M5 = 0.80 mm
- M6 = 1.00 mm
- M8 = 1.25 mm
- M10 = 1.50 mm
- M12 = 1.75 mm
🔷 Nut Dimensions (Hexagon Nut : B × H)
The dimensions of PPS/NT are defined to ensure proper load capacity and tightening performance.
- M2: 4 × 1.6 mm
- M2.5 / M2.6: 5 × 2.0 mm
- M3: 5.5 × 2.4 mm
- M4: 7.0 × 3.2 mm
- M5: 8.0 × 4.0 mm
- M6: 10.0 × 5.0 mm
- M8: 13.0 × 6.5 mm
- M10: 17.0 × 8.0 mm
- M12: 19.0 × 10.0 mm
Where B (Across Flats) represents the nut width and H represents nut thickness, both directly affecting tightening torque and locking capability.
🔷 Engineering Advantages
- Suitable for continuous operation in high-temperature environments
- Flame-retardant rating UL94 V-0
- Electrically insulating and non-magnetic
- Lighter than metal nuts, reducing structural load
- Resistant to corrosion and chemical exposure
- Ideal for non-metal fastening systems when used with PPS screws
🔷 Typical Applications
PPS/NT is used in high-voltage electrical equipment, electronic modules, machinery operating in corrosive environments, components near heat sources, and systems requiring reduced electrical conductivity.
📘 Summary
PPS/NT is a hexagon nut designed for technical applications requiring heat resistance, mechanical strength, and electrical safety.
It is well suited for industrial and electronic systems that require reliable non-metal fastening solutions.
