Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Performance Fastening: Designed to secure bolts and screws in mechanical and structural applications, featuring an inner pentagon slotted design for precise tool engagement and efficient assembly.
  • Weight Reduction & Strength: The unique cut-out pattern on the inner surface optimizes material distribution, reducing weight without compromising durability, ideal for aerospace, automotive, and industrial machinery.

Key features

  • 1. Advanced Material Technology

    • With a stainless steel body and zinc-flake coating, ensure corrosion resistance and longevity in harsh environments*. The galvanized and passivated finishes further enhance durability, outperforming standard steel fasteners in corrosive or high-stress conditions.

  • 2. Innovative Interactive Design

    • With the inner pentagon slotted design and hexagonal shape, achieve weight reduction while maintaining structural integrity for high-performance applications*. The customizable cut-out pattern optimizes grip, locking mechanisms, or airflow, surpassing traditional solid-core nuts.

  • 3. Precision Performance Parameters

    • With thread sizes ranging from M1.6 to M2.5 and metric compatibility, accommodate precise fitting in diverse mechanical assemblies*. The surface treatments (e.g., black oxide, chrome plating) ensure smooth threading and reduced wear compared to uncoated alternatives.

  • 4. Customizable Scenario Solutions

    • With OEM customization options for material (stainless steel/steel/plastic), surface finish, and cut-out patterns, tailor components to aerospace, automotive, or industrial needs*. The lightweight design excels in weight-sensitive applications versus conventional heavy-duty fasteners.

  • 5. Compliance with Global Standards

    • With RoHS and EPR (Germany) certifications, meet stringent environmental and safety regulations for global markets*. This ensures compliance with EU packaging laws and restricts hazardous substances, unlike non-certified competitors.

Supplier's note

  1. Technical Breakthroughs:

    • The pentagon slotted design reduces weight by 20% without compromising strength, ideal for drones or robotics.
    • EPR_Germany_Packing certification ensures compliance with EU packaging waste laws, reducing logistical hurdles.
    • 316 stainless steel in the Advanced Model offers 3x longer lifespan in corrosive chemical plants.

  2. Version Selection Guide:

    • Base Model: Best for general industrial use (e.g., machinery assembly) where cost efficiency is prioritized.
    • Advanced Model: Suited for marine or food processing environments needing enhanced corrosion resistance.
    • Pro Model: Choose for aerospace or extreme-temperature applications (e.g., engine components) requiring custom alloys and ultra-precise threads.

With the Pro Model’s Inconel alloy, you can withstand temperatures up to 800°C—20% higher than standard stainless steel. Pair its ultra-light pentagon slots with a black oxide finish to reduce glare in precision optics systems.
