Materials Available at JM Hardware® Used in Stud Bolt Manufacturing ​​​​​​​

At JM Hardware®, we offer stud bolts in a wide variety of materials to ensure optimal performance in different environments, including:

  • Carbon Steel
    Carbon Steel
    Commonly used for general-purpose applications. Offers good strength and affordability.
  • Stainless Steel (SS304, SS316, SS316L, etc.)
    Stainless Steel (SS304, SS316, SS316L, etc.)
    Ideal for applications requiring corrosion resistance, such as marine environments or chemical processing plants.
  • Alloy Steel
    Alloy Steel
    Provides excellent strength and durability, making it ideal for high-stress applications like power plants and oil & gas.
  • Hastelloy
    Hastelloy
    Hastelloy can be fabricated by a variety of Methods. Hastelloy alloy fastener can be forged, hot-upset, and impact extruded. Although the alloy tends to work-harden, it can also be successfully deep-drawn, spun, press formed or punched. Since it is a strong material with corrosion resistances, it has been used in nuclear and chemical reactors and also in valves and pipes in the chemical industries.
  • Inconel & Monel
    Inconel & Monel
    These materials are designed to withstand extreme temperatures, corrosion, and harsh environments.
  • Duplex and Super Duplex Stainless Steel
    Duplex and Super Duplex Stainless Steel
    These materials offer a combination of high strength and superior corrosion resistance, particularly in chloride-rich environments.

Surface Treatments  Available at JM Hardware®

Surface treatments enhance the durability and corrosion resistance of stud bolts. Depending on your project needs, we offer various surface finishes:

  • Zinc Plated
    Zinc Plated
    Provides moderate corrosion resistance and is typically used for indoor applications.
  • Hot-Dip Galvanizing
    Hot-Dip Galvanizing
    Offers enhanced protection against corrosion, ideal for outdoor and marine environments.
  • Black Oxide
    Black Oxide
    Provides a sleek finish with minimal corrosion resistance, suitable for indoor or low-humidity environments.

  • Yellow zinc plated
    Yellow zinc plated
    Plating with yellow zinc, or yellow zinc plating, is a surface treatment process that involves applying a thin layer of zinc onto a metal substrate through an electrochemical method. This layer not only enhances the aesthetic appeal of the metal by giving it a shiny, golden-yellow hue but also significantly boosts its corrosion resistance, durability, and overall protection against environmental degradation. Yellow zinc plating achieves its distinctive color through the addition of certain dyes or additives during the plating process

Production Processes of Stud Bolts At JM Hardware®

We utilize advanced manufacturing processes to ensure our stud bolts meet the highest quality standards:


    • 1. Raw Material Selection
      1. The process begins with choosing the right materials for your specific application, ensuring quality from the start.
    • 1.	Raw Material Selection
    • 2. Cold Forging or Hot Forging

      Depending on the material and required strength, the bolts are either cold forged (for smaller bolts) or hot forged (for larger, stronger bolts).

    • 2.	Cold Forging or Hot Forging
    • 3. Thread Rolling

      The threads on our stud bolts are formed using a thread rolling machine, which increases the bolt’s strength by compressing the material rather than cutting it.

    • 3.	Thread Rolling
    • 4. Heat Treatment
      1. After forming, the bolts are heat-treated (such as quenching and tempering) to achieve the desired hardness and mechanical properties.
    • 4. Heat Treatment
    • 5. Surface Treatment
      1. Depending on the customer’s requirements, various coatings are applied to enhance corrosion resistance and appearance.
