Flat Head Blind Hole Press-in Rivet Nut Column - Serrated Knurl - Yellow Zinc Plated 304 SS - M4 to M8

Flat Head Blind Hole Press-in Rivet Nut Column - Serrated Knurl - Yellow Zinc Plated 304 SS - M4 to M8

Flush-mount blind hole rivet nut columns for industrial use. 304 stainless steel with yellow zinc plating, serrated underhead for anti-rotation. M4-M8 sizes. Longer lengths available. For machinery, enclosures, & frames.

Our **Flat Head Blind Hole Pressure Rivet Nut Columns** provide robust, reliable threaded points in metal panels where a clean, flush finish is critical. The **90° countersunk head** sits perfectly flat with the surface, while the **serrated knurl (flower teeth) under the head** bites into the material, preventing rotation during installation and use. Manufactured from **A2-70 (304) stainless steel** and finished with a smooth, corrosion-resistant **yellow zinc plating** (tri-valent chromate), they offer an excellent balance of performance and value for industrial applications. The **blind hole (non-through hole)** protects threads from damage, and the **non-full thread design** optimizes strength-to-weight ratio.

Primary Uses & Applications:

    *   **Industrial Machinery:** Mounting components, panels, and guards on CNC machines, presses, and conveyor systems.
    *   **Electrical Enclosures:** Providing strong threaded inserts for service windows, mounting plates, and covers in control cabinets and server racks.
    *   **Telecom Racks:** Installing threaded standoffs for PCB mounting in 19" racking systems and base station cabinets.
    *   **Automotive Framing:** Securing brackets and modules in vehicle frames, busbar supports, and battery boxes.
    *   **General Fabrication:** Creating durable threaded points in frames, supports, and assemblies made from sheet metal.

How to Use:

    1.  **Hole Preparation:** Punch or drill a precision hole. The hole diameter is critical and should match the recommended size for the specific nut column diameter (typically slightly smaller than the knurled diameter).
    2.  **Tool Setup:** Insert the nut column into the mounting hole of a **pneumatic or hydraulic rivet nut press**. Ensure the flat head is seated against the tool's flat anvil.
    3.  **Installation:** Align the tool's pressing ram precisely over the nut column's blind end. Activate the tool to apply steady pressure. The serrated knurl under the head will be pressed into the surrounding material, permanently locking the nut in place.
    4.  **Quality Check:** After installation, verify that the head is flush with the surface. Check thread integrity using a **go/no-go gauge**.
