Understanding 12.9% Threaded Rods Characteristics, Applications, and Benefits

Threaded rods are essential components in various engineering and construction applications. Among the many grades available, the 12.9% threaded rod stands out due to its high-strength properties and versatility. This article delves into the characteristics, applications, and benefits of using 12.9% threaded rods in different industries.

What is a 12.9% Threaded Rod?

The designation “12.9” refers to the strength of the material used to manufacture the threaded rod, according to the ISO 8992 standard regarding metric fasteners. The first number (12) represents the tensile strength, which is approximately 1200 MPa, while the second number (9) indicates the yield strength, equating to around 900 MPa. Threaded rods of this grade are typically composed of carbon steel that has undergone heat treatment, making them exceptionally strong and capable of withstanding considerable stress.
