Welcome to Teshi Fasteners’ Double-End Stud Bolts page, where versatility and reliability are paramount. As a leading manufacturer, supplier, and exporter of fasteners in India, we offer a comprehensive range of double-end stud bolts designed to meet diverse industrial, construction, and mechanical requirements.

Teshi Fasteners is renowned for producing high-quality double-end stud bolts that meet rigorous industry standards. Our double-end stud bolts are available in a variety of sizes, materials, and finishes, offering flexible solutions for a range of applications. Whether for structural support, machinery, or specialized projects, our double-end stud bolts deliver exceptional strength, durability, and performance.

Double-end stud bolts are fasteners with threads extending along both ends of the bolt, while the center section remains smooth. This design allows for secure fastening on both ends, making them ideal for applications where a bolt needs to be inserted through a material and secured with nuts on both sides. Double-end stud bolts are widely used in construction, machinery, and industrial settings where strength and stability are crucial.

At Teshi Fasteners, we manufacture double-end stud bolts using high-quality materials to ensure durability and strength. Available in materials such as carbon steel, stainless steel, and alloy steel, our bolts come with various coating options to enhance corrosion resistance and extend their service life.

  • Threaded Ends: Threads run along both ends of the bolt, allowing for secure fastening with nuts or tapped holes.
  • Smooth Center Section: The unthreaded central portion provides stability and alignment in applications requiring through-bolting.
  • High Strength: Made from premium materials to offer excellent tensile strength and durability.
  • Versatile Use: Suitable for various applications, including structural support, machinery, and industrial projects.
  • Corrosion Resistance: Available with protective coatings such as galvanization or stainless steel to withstand harsh environments.
  • Customizable Options: Offered in different sizes, materials, and finishes to meet specific application needs.
  • Secure Fastening: Threaded ends enable reliable connection with nuts or tapped holes on both sides, ensuring stability.
  • Enhanced Alignment: The smooth center section allows for proper alignment and support where through-bolting is required.
  • Durability: Constructed from high-quality materials to handle substantial stress and environmental conditions.
  • Corrosion Resistance: Coatings and material options protect against rust and corrosion, extending the bolt’s lifespan.
  • Versatility: Ideal for various applications, from structural support to mechanical assemblies.
  • Customizable: Available in different sizes and materials to suit specific requirements.
