Customized Carbon Steel M10 Internal Threaded Hollow Hex Bolt With Holes Yellow Zinc

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Secure Fastening with Internal Thread: Designed for precise assembly in machinery, equipment, and structural components, featuring an internal threaded shank compatible with standard nuts and fittings.
  • Hollow Hex Head with Central Hole: Combines weight reduction and drainage capabilities, preventing corrosion and debris buildup while maintaining structural integrity.
  • Versatile Material & Coating: Carbon steel construction ensures durability, reinforced by a yellow zinc surface treatment for corrosion resistance and aesthetic appeal.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a corrosion-resistant yellow zinc-coated carbon steel body, you can ensure long-lasting durability in humid or chemically exposed environments. The zinc plating provides ~30% better corrosion protection compared to uncoated steel bolts*.

  • 2. Precision-Engineered Interactive Design

    • With a hollow hex head and central hole, you can achieve precise torque control using standard wrenches while reducing weight by ~15% compared to solid hex bolts*. The design also allows moisture drainage, minimizing rust buildup.

  • 3. Versatile Performance Parameters

    • With M8–M16 thread compatibility and lengths from 20mm to 70mm, you can adapt to diverse fastening needs, outperforming single-size bolts in multi-application projects*.

  • 4. Scenario-Specific Solutions

    • Designed for industrial and outdoor scenarios, the hollow head prevents moisture entrapment, making it ~25% less prone to corrosion than non-drainage bolts in wet environments*. The DIN-standard model ensures reliability in structural applications.

  • 5. Certified Industrial Compliance

    • Complying with DIN standards for mechanical fasteners, you can guarantee safety and compatibility with global industrial applications, unlike non-certified alternatives*.

Supplier's note

  1. Three Technical Breakthroughs:

    • Enhanced Corrosion Resistance: The Pro model’s 240hrs salt spray rating triples industry benchmarks, enabling safe use in marine or chemical environments.
    • Hollow Head Design: Reduces weight by 20% while maintaining strength, ideal for aerospace or lightweight machinery.
    • Precision Threads: Class 4g threading ensures 20% faster assembly compared to standard bolts.

  2. Optimal Version Selection:

    • Base Model: Suitable for general industrial assembly (e.g., machinery fastening).
    • Advanced Model: Recommended for automotive or outdoor applications needing moderate corrosion resistance.
    • Pro Model: Best for harsh environments (e.g., offshore platforms) where extreme durability and precision are critical.

With the Pro model’s 800MPa tensile strength and Class 4g threading, you can ensure secure fastening in heavy-duty applications. The hollow design paired with yellow zinc plating delivers both aesthetic appeal and corrosion protection, making it a top choice for demanding industries.
