Various Types of Standards of Threaded Rod Fasteners?

Threaded rods, also known as studs, are long rods with threading on both ends used to fasten materials together. They come in various types and adhere to specific standards to ensure their compatibility, reliability, and performance in diverse applications. Here are some types of threaded rod standards:

Common Types of Threaded Rod Standards

1. ISO (International Organization for Standardization)

  • ISO 976: Specifies the general dimensions of metric series hexagon head bolts (with threads from M1.6 to M64).
  • ISO 898-7: Covers mechanical properties of fasteners—part 7: Torsional test and minimum torques for bolts and screws with nominal diameters 1 mm to 10 mm.

2. ASTM (American Society for Testing and Materials)

  • ASTM A193: Standard specification for alloy-steel and stainless steel bolting materials for high-temperature service.
  • ASTM F1554: Covers anchor bolts designed for anchoring structural supports to concrete foundations.

3. DIN (Deutsches Institut für Normung – German Institute for Standardization)

  • DIN 976: Specifies metric threads, diameters, and lengths of fully threaded rods.
  • DIN 975: Specifications for threaded rods with coarse thread.

4. BS (British Standards)

  • BS 4190: Covers metric hexagon head bolts and screws, including full thread and shorter thread lengths.

Factors Influencing Choice of Standard

The selection of a specific threaded rod standard depends on various factors:

  • Thread Type and Size: Different standards accommodate various thread types (e.g., metric, UNC, UNF) and sizes.
  • Material and Coating: Standards vary based on the materials used, such as steel, stainless steel, or alloys, and coatings for corrosion resistance.
  • Application Requirements: Threaded rods are chosen based on load-bearing capacities, environmental conditions, and specific fastening needs.

Importance of Adherence to Standards

Adhering to established threaded rod standards ensures compatibility, reliability, and performance in various applications. It guarantees that these components meet specified dimensional, mechanical, and material requirements, ensuring safety and reliability across diverse industries.


Threaded Rods are crucial components in numerous applications, providing a versatile means of fastening materials together. Understanding the different types of Threaded Rod standards is vital for selecting the right rod for specific applications. Adherence to these standards ensures that these components play a significant role in enhancing the safety, reliability, and functionality of assemblies and structures.
