Stainless Steel Flat Head Blind Rivet Nut Column M5-M12 Zinc Plated

High-strength blind hole rivet nut columns for heavy-duty applications. A2/A4 SS, deep serrations, thick walls. Blue-white zinc plating. M5-M12. For power, telecom, & machinery. Custom specs available.

Designed for demanding industrial environments, our Heavy-Duty Flat Head Blind Hole Rivet Nut Columns feature deeper and larger serrations under the head and a thicker wall structure to withstand extreme vibrational forces, higher torque loads, and repeated assembly/disassembly. Made from higher-strength A2-80 or A4-80 (316) stainless steel and finished with blue-white zinc plating, these nuts provide superior push-out and torque-out strength for critical applications in energy, transportation, and heavy machinery. The blind hole design is essential for sealing out moisture and contaminants.

• Power & Energy: Mounting circuit breakers, contactors, and busbars in electrical cabinets and power distribution units (PDUs).
• Telecommunications: Securing heavy RF amplifiers, filter units, and base station hardware to ruggedized outdoor enclosures.
• Railway & Mass Transit: Fastening critical components inside train control boxes, door mechanisms, and under-carriage equipment where vibration is intense.
• Engineering Machinery: Providing hardened threads in hydraulic valve blocks, sensor mounts, and access panels on construction and agricultural equipment.
• Renewable Energy: Assembling inverter housings, solar tracker linkage systems, and wind turbine control cabinets.

1. Hole Preparation: The hole must be drilled to a tight tolerance. Deburr thoroughly to ensure the serrations can bite cleanly into the material. For thicker panels, ensure hole perpendicularity.
2. Tool Setup: These high-strength units require a high-force hydraulic pressing tool or a heavy-duty pneumatic press. Confirm the tool's capacity exceeds the required installation force.
3. Installation: Position the nut column in the hole. The pressing ram must apply force evenly to the entire end surface of the column. Apply force steadily until a clear "bottoming" feel is achieved.
4. Validation: For critical applications, conduct a torque-test on a sample installation to verify it meets the specified torque-out value before full-scale production.
