PC Hexagon nut Overview
PC Hexagon nut is a specialized non-metallic fastener made from Polycarbonate, an engineering thermoplastic celebrated for its exceptional impact resistance, structural integrity, and optical clarity.
Product Parameters
PC 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) |
| M2 | 0.4 mm | 4.0 mm | 1.6 mm |
| M2.5 | 0.45 mm | 5.0 mm | 2.0 mm |
| M3 | 0.5 mm | 5.5 mm | 2.4 mm |
| 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 |
Key Features
Polycarbonate’s properties define the distinguishing features of the PC Hexagon Nut:
Exceptional Impact Strength: PC is one of the toughest available thermoplastics, providing outstanding resistance to shattering or cracking from physical impact.
High Optical Clarity: PC nuts are transparent, making them suitable for use with clear panels or in assemblies where visual inspection of the underlying structure is necessary.
Good Mechanical Strength: Offers better stiffness and resistance to creep than commodity plastics, allowing for more reliable load distribution in a hex bolt nut assembly.
Thermal Stability: Maintains its structural form and function at service temperatures higher than many commodity plastic screws or nylon hex nut options.
Electrical Insulation: It is a reliable dielectric, effectively preventing short circuits and galvanic corrosion in bolt hex nut assemblies.
Dimensional Compliance: Manufactured to adhere to precise hex nut diameter and hex nut height standards.
Key Polycarbonate (PC) Properties
Advantages vs Disadvantages
| Category | ✅ Advantages (Pros) | ❌ Disadvantages (Cons) |
| Performance | Extreme Impact Resistance and toughness. High Clarity. Good Structural Strength relative to other plastics. | Chemical Vulnerability: Susceptible to degradation and cracking from many solvents, ketones, and strong bases, unlike PEEK or PTFE. |
| Protection | Reliable Electrical Insulation. Good thermal stability. Compatible with plastic hex nut caps for added safety/aesthetics. | Scratch Resistance: The surface is relatively soft and easily scratched, impairing clarity over time, unlike glass. |
| Comparison | Superior toughness to nylon hex nut. Better thermal stability than PVC. Addresses the lock nut vs hex nut decision when impact resistance is vital. | UV Degradation: Standard PC is prone to yellowing and embrittlement with prolonged, direct sun exposure if not UV stabilized. |
| Installation | Available in standard metric hex nuts and imperial hex nut sizes. | Torque Limitations: As a polymer, its maximum installation torque is significantly lower than metal hex lock nuts, limiting the clamping force in the final assembly. |
Applications
PC Hexagon Nuts are critical in applications where durability, visibility, and insulation are required simultaneously.
Lighting and Displays: Used to secure clear covers, lenses, and transparent enclosures in LED fixtures, safety shields, and signs due to clarity and toughness.
Electrical and Electronics: Employed as an insulating fastener for busbars, battery enclosures, and control panels where high impact resistance is also necessary.
Safety Guards and Equipment: Used on machinery with transparent protective windows where fasteners are exposed to potential impact from tools or materials.
Security Enclosures: Utilized in tamper-resistant or vandal-proof assemblies due to the material’s inherent strength.
General Fastening: Used in place of metal hex nuts (even stainless steel hex nuts) where corrosion resistance and non-conductivity are paramount, and mechanical shock is a risk.
Packaging & Delivery
Standard packaging includes PE bag, foam cover, and one double-deck corrugated outer carton for safety during transit. Delivery time is 5-15 working days depending on the quantity.
