Hex Flange Sealing Nut

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Flange Design & Secure Fastening: The hexagonal flange provides a wide contact surface to distribute torque evenly, preventing rotation and loosening under high stress or vibration. Ideal for applications requiring robust mechanical joints.
  • Material Versatility & Sealing: Constructed from materials like stainless steel (corrosion-resistant), plastic (lightweight), or nylon (chemical-resistant), these nuts ensure durability in diverse environments while maintaining tight seals in threaded connections.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a stainless steel and brass composite construction, you can achieve 30% higher corrosion resistance compared to standard carbon steel nuts* [*Disclaimer: Based on internal testing; results may vary by environment]. The brass flange and stainless steel core ensure durability in harsh industrial settings.

  • 2. Enhanced Interactive Design for Ease of Use

    • With a flange design and hex head, you can prevent rotation and simplify installation compared to standard nuts*. The flange provides a stable gripping surface, reducing slippage during high-torque applications.

  • 3. Precision Performance for High-Torque Applications

    • With an M2 metric thread, you can handle up to 50% higher torque loads than smaller thread sizes* [*Disclaimer: Performance varies by material and application]. Ideal for securing bolts in machinery and structural components.

  • 4. Industrial-Grade Scenario Adaptability

    • Designed for mechanical and industrial use, you can maintain stability in high-vibration environments* [*Disclaimer: Test results apply to stainless steel variants]. The flange’s broad surface distributes force evenly, minimizing bolt stripping.

  • 5. Material Customization for Diverse Applications

    • With customizable material options (stainless steel, nylon, or plastic), you can tailor the nut to specific environmental needs* [*Disclaimer: Customization requires manufacturer confirmation]. Stainless steel variants may meet food-grade standards in select configurations.
