M3 Nylon Nut

M3 Nylon Hex Nut is a lightweight, non-conductive, and corrosion-resistant fastening solution essential for electronics, robotics, and lightweight structural assemblies. Manufactured from durable Nylon 66, this hex nut provides reliable mechanical securement for M3 screws and bolts while offering superior insulating properties compared to standard metal fasteners. Consequently, using Nylon nuts eliminates the risk of short circuits and grounding issues in sensitive electronic enclosures. Furthermore, the M3 size is universally compatible with standard small-scale hardware, making this component a versatile choice for prototyping and permanent installations where weight reduction is a primary design goal. Therefore, designers frequently choose this nylon nut when they need a low-cost, high-performance insulator and fastener combination.

Key Features:

• Electrical Insulation: The Nylon 66 material provides high dielectric strength, ensuring excellent electrical isolation between components and PCBs.
• Corrosion Resistance: Offers immunity to rust, moisture, and many chemicals, making it suitable for damp or corrosive operating environments.
• Lightweight Design: Significantly reduces the overall weight of the assembly compared to steel or brass nuts, benefiting portable and aerospace applications.
• Non-Magnetic: Does not interfere with sensitive magnetic components, critical for sensors, motors, and magnetic shield assemblies.
• Standard Metric Thread: Features the universally recognized M3 metric thread standard, ensuring compatibility with all M3 screws and standoffs.

Technical Specifications:

• Thread Size: M3 (Nominal Diameter: 3 mm)
• Thread Pitch: 0.5 mm (Standard Coarse Pitch)
• Dielectric Strength: ≥ 14 kV/mm (Excellent insulator)
• Tensile Strength: ≈ 80 N/mm²

Mechanical Specifications:

• Nut Type: Hexagonal Nut
• Drive Type: External Hex Drive (Requires 5.5 mm Wrench)
• Mounting Style: Threaded Fastener
• Recyclability: Recyclable Plastic, supporting sustainable design practices.

Dimensions:

• Nominal Thread Diameter (D): 3.0 mm
• Across Flats (AF) / Wrench Size: 5.5 mm
• Nut Height (H): ≈ 2.4 mm
• Weight: < 0.1 g per unit (Ultra-lightweight)
• Standard: Conforms to DIN 934 or equivalent ISO metric standards.

Pinout and Wiring:

• Function: Mechanical Fastener. (Note: This component is passive and requires no electrical connection or wiring.)
• Installation Method: Thread onto an M3 screw, bolt, or standoff. Tighten using a 5.5 mm wrench or nut driver.
• Wiring Note: Avoid overtightening, as plastic fasteners have a lower maximum torque specification than metal equivalents; over-torquing can strip the thread.
