Galvanized Zinc Plated DIN7340 Knurled Blind Riveting Rivet Nut, custom fastener

Our Knurled Blind Rivet Nuts are engineered to streamline your fastening processes:

• Single-Side Installation (Blind Application): This is the primary advantage – they can be installed from only one side of the workpiece, making them essential for applications with limited access to the back panel or tube.

• Knurled Body: The textured, knurled body provides enhanced grip against the hole wall during installation. This helps prevent the rivet nut from spinning in the hole during the riveting process and when the mating screw or bolt is subsequently tightened.

• Creates a Strong Internal Thread: Once installed, the rivet nut forms a durable load-bearing thread in thin materials that are too thin to be tapped directly.

• Tool-Friendly Installation: Requires a dedicated rivet nut installation tool (manual, pneumatic, or hydraulic), a standard tool in many assembly environments.

Key Advantages for Your Automotive Applications:

Utilizing these specialized rivet nuts provides distinct benefits tailored for the automotive sector:

• Enhanced Resistance to Spin-Out: The knurled body significantly increases the rivet nut's resistance to rotation (torque-out) once installed, crucial for maintaining joint integrity under the vibrations and stresses common in vehicles.

• Improved Pull-Out Strength: When properly installed, they provide reliable resistance to axial pull-out forces.

• Corrosion Resistance: The Galvanized Zinc Plating provides a vital protective layer against rust and corrosion, ensuring the longevity and reliability of the fastener in various automotive environments exposed to moisture, road salt, and chemicals. (Surface treatment options commonly include Plain, Zinc Plated (ZP), Galvanized, HDG, Dacromet).

• Versatile Material Compatibility: Suitable for creating threads in diverse materials used in automotive, including various steels (Carbon Steel, Alloy Steel, Stainless Steel), aluminum, and certain plastics or composites. (Materials commonly include Carbon Steel, Alloy Steel, Stainless Steel, Brass, Copper).

• Available in Various Grades: Manufactured in different strength grades (e.g., 4.8, 8.8, 10.9, 12.9, A2-70, A4-70, A4-80) to meet specific load-bearing requirements of different automotive applications.

• Standard Compliant: Produced according to various standards (like DIN, GB, UNC, BSW, JIS etc.), ensuring consistent dimensions and performance.

Ideal for:

Galvanized Zinc Plated Knurled Blind Rivet Nuts are ideally suited for automotive applications requiring a reliable internal thread in thin materials or blind locations:

• Body Panel Attachment: Creating robust threads for mounting exterior or interior body panels and trims.

• Securing Brackets to Frames or Tubing: Providing anchor points for mounting components to thin-walled frames or structural tubing.

• Interior Component Mounting: Fastening dashboard elements, consoles, or seating components to thin underlying structures.

• Creating Threaded Holes in Plastics or Composites: Ideal for mounting accessories or components onto plastic body panels or composite structures.

• Applications with Limited Access: Essential in areas where access to the back side of the material is restricted.

• Components Requiring Service: Provides a durable thread that can withstand repeated tightening and loosening for maintenance purposes.
