Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Precision Torque Transmission: The Cold Heading Fasteners feature a custom tooth shape design enabling secure engagement with gears or components for precise rotational force transfer.
  • Versatile Fastening Solutions: Designed with threaded sections (M4) and customizable tooth profiles to adapt to diverse mechanical applications, ensuring robust fastening in dynamic environments.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With zinc-plated steel construction, you can ensure long-lasting durability in corrosive environments. Outperforms uncoated fasteners by resisting rust and degradation for up to 50% longer* in harsh industrial settings.

  • 2. Precision Custom Tooth Design

    • With a custom tooth shape, you can achieve precise alignment and torque transfer in mechanical systems. The interlocking teeth design provides 20% better engagement accuracy than standard nuts*, reducing slippage in high-stress applications.

  • 3. Universal Thread and Measurement Compatibility

    • With M4 thread size and dual metric/imperial measurement support, you can ensure seamless fitment across global standards. Works reliably in both domestic and international machinery setups where traditional fasteners may require conversions*.

  • 4. Versatile Scenario Adaptability

    • With robust steel and gear-like engineering, you can deploy these fasteners in heavy-duty industrial machinery or automotive components. Designed for continuous operation in commercial settings, outperforming plastic-based alternatives in high-torque scenarios*.

  • 5. Eco-Conscious Surface Treatment

    • With zinc-plated surface treatment, you can meet eco-friendly and safety compliance standards. The coating adheres to industrial environmental regulations*, ensuring safe use in food-grade and chemical-exposed environments (subject to manufacturer’s confirmation).
