Hex Nut M20 Polyamide 26 mm Grey Pitch 1.5

Polyamide hex nut M20 with a 26 mm outer dimension and 1.5 mm thread pitch in grey. This nut is made from glass-reinforced polyamide, providing a lightweight and corrosion-resistant alternative to metal fasteners. It is suitable for use with M20 threaded rods or bolts and is intended for assemblies where reduced electrical conductivity, chemical resistance and lower weight are required.

Advantages

The polyamide construction ensures resistance to rust and many chemicals while offering lower thermal and electrical conductivity compared with steel. The 26 mm external size and standard 1.5 mm pitch match common M20 fastening components for reliable engagement. The grey finish provides a neutral appearance for visible installations and helps conceal minor surface wear. Reduced weight and non-metallic properties make the nut easier to handle and safer in applications sensitive to electrical continuity.

Suitable for

• Electrical assemblies where reduced conductivity is required
• Outdoor equipment and fixtures exposed to moisture
• Lightweight structures and furniture where metal fasteners are undesirable
• Corrosion-prone environments and chemical-exposed installations
• Prototyping and applications requiring easier manual handling

Key specifications

• Material: polyamide (glass-reinforced)
• Finish / color: grey
• Properties: corrosion-resistant, low electrical conductivity, reduced weight

How to use

Use this hex nut with compatible M20 threaded rods or bolts. Ensure threads of mating components are clean and undamaged before assembly. Hand-start the nut onto the bolt or rod, then tighten with an appropriate wrench or socket sized for a 26 mm across-flats nut until the required clamping force is achieved. Avoid excessive torque to prevent deformation of the polyamide material; follow torque values recommended for polyamide fasteners or apply conservative torque relative to equivalent metal fasteners.

Usage recommendations

Store the nuts away from direct UV exposure for prolonged periods to minimize potential long-term degradation. For applications involving prolonged contact with aggressive solvents or high continuous temperatures, verify chemical compatibility and operating temperature limits of the polyamide material before use.
