Helical Knocked Inserts

Brass Helical Knurled Inserts are precision-engineered threaded inserts manufactured from high-quality brass (or alternative alloys) using a knockdown process. Conex Metals produces these inserts to offer enhanced strength, superior resistance to pull-out, and a consistent, reliable thread in softer materials or components where traditional threading may fail. Their unique ‘helical Knurled’ design combines the benefits of a coil-type insert with the robustness achieved through a knockdown process, ensuring secure engagement and long-term durability. As one of India’s leading manufacturers and suppliers, we produce high-quality Helical Knurled Inserts at our advanced facility in Jamnagar. Our inserts are trusted worldwide for their precision, strength, and superior quality.


Key Features of Brass Helical Knurled Inserts

  • Material & Construction:
    Manufactured from premium brass, these inserts are designed for applications where corrosion resistance and durability are essential. Variants can also be produced in stainless steel, phosphor bronze, or other alloys based on customer requirements.
  • Knockdown Process:
    The “Knurled” design refers to the manufacturing process where the insert is cold-forged or Knurled down to achieve a precise and tight thread engagement. This process increases the insert’s strength and ensures consistent dimensions.
  • Enhanced Pull-Out Resistance:
    The helical design, combined with the knockdown manufacturing technique, provides excellent resistance to pull-out, making them ideal for repair or reinforcement of stripped threads in softer materials like aluminum, plastics, or die castings.
  • Versatile Application:
    These inserts are commonly used in applications requiring durable internal threads—such as in automotive, aerospace, electronics, and furniture assemblies. They are particularly beneficial for repair applications where the original threading has been compromised.
