AVK series comply - Threaded Insert ,Large Flange Splined , Closed End - TSBS-C

In the demanding environments of modern manufacturing, a fastening failure is not just an inconvenience—it is a liability. Engineered and manufactured in Taiwan, our Large Flange Straight Knurled Waterproof Blind Rivet Nuts represent the pinnacle of cold-forging and CNC precision. These fasteners are specifically designed for industries where moisture ingress, structural vibration, and material thinning present constant challenges. By combining high-strength load-bearing capabilities with a hermetic seal, we provide a "Taiwan-made" guarantee of reliability for your most critical assemblies.

Key Features & Benefits

• Closed-End Waterproof Design: The hermetically sealed tail prevents the passage of liquids, gases, and debris through the fastener, protecting internal components from corrosion and electrical shorts.

• Enhanced Large Flange: Provides a significantly larger bearing surface to reinforce the hole and prevent "pull-through," making it ideal for use in thin-gauge metals, plastics, and composite materials.

• Straight Knurled Body: The precision-machined knurling offers superior resistance to torque-to-turn. Once installed, the body bites into the parent material, ensuring the insert remains stationary even under high-vibration conditions.

• Blind Installation Versatility: Perfect for applications where only one side of the workpiece is accessible, reducing labor costs and assembly time.

Applications

• Automotive Tier 1: Ideal for chassis components, exterior trim mounting, and EV battery enclosures where IP-rated sealing is mandatory.

• Marine Engineering: Used in deck hardware and hull fittings to combat the relentless exposure to saltwater and humidity.

• Aerospace & Defense: High-precision fastening for cabin interiors and electronic housing that requires lightweight yet high-torque resistance.

• Heavy Machinery: Securing control panels and exterior panels on agricultural or construction equipment exposed to harsh weather.

Technical Highlights & Comparison

The Cold-Forging & CNC Advantage

Our hybrid manufacturing process utilizes Precision Cold-Forging to optimize the grain flow of the metal, significantly increasing the tensile strength and fatigue resistance of the rivet nut. Following forging, critical tolerances are refined via CNC machining, ensuring that thread accuracy and flange concentricity meet the rigorous standards required for automated assembly lines.

Sealed Integrity: Closed-End vs. Open-End

Traditional open-end (through-hole) rivet nuts offer a convenient threaded point but leave a path for moisture and contaminants to bypass the fastener. Our Waterproof Closed-End variant acts as a permanent barrier. In salt-spray testing and high-pressure wash-down scenarios, the closed-end design effectively eliminates "virtual leaks" and prevents the internal oxidation that often leads to catastrophic joint failure in conventional fasteners.
