Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Precision Fastening: The hex socket head design enables precise torque control and secure fastening using a hex key wrench, ideal for applications requiring mechanical reliability.
  • Material Versatility: Constructed from materials like carbon steel, stainless steel (304), and bronze, the screws offer corrosion resistance, high strength, and durability for diverse environments.
  • Adjustable Screw Rod: The adjustable length and thread size (e.g., M6, M2.5) accommodate customization for specific fastening needs, from light-duty to heavy-duty applications.

Key features

  • 1. Material Technology: Corrosion-Resistant Stainless Steel & Black Oxide Coating

    • With 304 stainless steel and a durable black oxide coating, you can achieve superior corrosion resistance and longevity in harsh environments. This combination outperforms standard carbon steel screws in moisture-prone or chemically exposed applications.*

  • 2. Customizable Finishes for Versatile Applications

    • With finishes like zinc-plated, chrome-plated, or anodized options, you can tailor the screw to specific use cases—enhancing aesthetics or corrosion protection compared to single-finish competitors.*

  • 3. Precision Hex Socket Design for Controlled Performance

    • With a hex socket head and precise thread sizing (M6/M2.5), you can ensure accurate torque control and secure fastening, ideal for mechanical assemblies where alignment and reliability are critical.

  • 4. Adaptability Across Scenarios

    • With metric/inch measurement systems and materials like bronze or aluminum, you can seamlessly adapt to both industrial machinery and lightweight applications, offering broader compatibility than single-standard screws.*

  • 5. RoHS Compliance for Safe, Eco-Friendly Use

    • With RoHS certification, you can meet stringent environmental and safety regulations, ensuring compliance in markets where non-compliant products may be restricted.*

Supplier's note

  1. Three Technical Breakthroughs:

    • Material Flexibility: 304 stainless steel in the Advanced Model offers 30% better corrosion resistance than base carbon steel.
    • Thread Customization: Pro Model’s ISO 12.9 thread strength enables 20% higher load-bearing capacity than industry benchmarks.
    • Finish Innovation: Black oxide coating in the Base Model provides a sleek appearance while resisting mild corrosion.

  2. Optimal Version Selection:

    • Base Model: Ideal for general assembly (e.g., furniture, light machinery) where cost-efficiency is prioritized.
    • Advanced Model: Perfect for corrosive environments (e.g., marine equipment) thanks to its stainless steel and enhanced finish.
    • Pro Model: Best for heavy-duty applications (e.g., automotive, aerospace) requiring extreme strength and chemical resistance.

With the Pro Model’s 316 stainless steel, you can ensure safe handling of acidic chemicals in industrial settings. Pair its premium finish with high-strength threads to achieve unmatched durability and longevity.
