A4-80 Stainless Steel Hex Standoff M3-M8, 31mm Length, Blue-Zinc Plating

Product Specification

Heavy Duty Hex Standoff - Male-Female - A4-80 Stainless Steel - Blue-Zinc - for Industrial Use - M3 to M8

Heavy-duty male-female hex standoffs. A4-80 (316) stainless steel, blue-zinc plating. For industrial equipment, telecom, & outdoor enclosures. Sizes M3-M8. Fully customizable specs like H4.75-M3x31+6.

Designed for demanding industrial applications, our Heavy-Duty **Hex Standoffs** provide robust spacing and mounting solutions where strength and reliability are paramount. The **H4.75-M3x31+6** size is built to create durable, high-clearance connections in challenging environments. Made from **A4-80 (316) Stainless Steel** with a protective **blue-white zinc plating**, they offer superior resistance to corrosion, vibration, and moisture compared to standard A2-70 grade, making them suitable for industrial controls, telecommunications infrastructure, and outdoor applications.

Primary Uses & Applications:

    *   **Industrial Automation:** Mounting PCBs in PLC cabinets, motor drives, and robotic systems where shock, vibration, and humidity are present.
    *   **Telecommunications Infrastructure:** Used in 5G base stations, network switches, and outdoor cabinets requiring mechanical durability and environmental resistance.
    *   **Power Electronics:** Spacing and mounting boards in power supplies, inverters, and battery management systems within industrial settings.
    *   **Outdoor & Marine Equipment:** Providing corrosion-resistant mounting points in sensor housings, navigation equipment, and control units exposed to the elements.
    *   **Transportation Electronics:** Securing control units in automotive, rail, and marine applications (non-safety-critical).

How to Use:

    1.  **Preparation:** Ensure the tapped holes in the base material are clean and free of debris. Using stainless steel screws is recommended for optimal corrosion performance match.
    2.  **Installation:** Use a **correctly sized hex wrench or socket**. Screw the male thread into the base material. The A4-80 stainless steel is stronger but can be prone to galling (cold-welding); using a moderate speed and avoiding over-tightening is advised.
    3.  **Final Assembly:** Place the component over the standoff and secure it with an appropriate **stainless steel machine screw**. The deep female thread (25mm) allows for a strong connection with various material thicknesses.
    4.  **Torque Control:** For critical applications, use a torque wrench according to the specifications for A4-80 stainless steel to ensure a secure connection without damaging the threads.
    5.  **Custom Solutions:** We can manufacture standoffs to your exact specifications to solve unique design challenges involving space constraints or specific environmental exposures.
