High-temperature fasteners are essential for applications in critical industries such as the energy, aerospace and chemical industries, where components must withstand extreme conditions without compromising safety and efficiency. In this article, we will explore the materials used for high-temperature fastening, their performance and specific applications in these industries.

History and development

Fasteners have been used in extreme conditions for a long time, dating back to early industrial applications where high heat was a significant challenge. The need for materials capable of maintaining their integrity at high temperatures led to the development of special alloys and advanced surface treatments. Technological development led to bolts capable of withstanding not only heat but also specific mechanical and environmental stress.

Technological evolution

The technology behind high-temperature fasteners has evolved significantly. Today, bolts are made from advanced materials such as alloy steels, nickel alloys, and titanium. These materials are selected for their capability to maintain mechanical strength and chemical stability.

Alloyed steels: These steels offer good resistance to temperatures up to 750 °F (400 °C), commonly used in applications for the energy and chemical industries.

Nickel alloys: These alloys can withstand very high temperatures, over 1.800 °F (1.000 °F) ideal for aerospace applications.

Titanium: This material combines light weight and resistance to high temperatures, used especially in aerospace components and chemical plants.

Modern applications

High temperature fasteners are used in several industries:

Energy industry: These bolts are essential for gas turbines, boilers and nuclear plants where bolts must withstand intense and variable heat conditions. Ensuring safety and efficiency in these environments is crucial in order for power plants to continue their regular operations.

Aerospace industry: In jet engines and aircraft structures, where light weight and resistance to extreme temperatures are critical. These bolts must keep their integrity even at take-off and landing, when temperatures and stresses vary rapidly.

Chemical industry: In reactors and chemical production plants, where components must withstand not only heat but also aggressive chemical conditions. Resistance to corrosion and oxidation is essential to avoid contamination and ensure the purity of chemical products.

In the world of mechanics and constructions, choosing the right screws is essential to guarantee the safety and durability of structures. In this article, we will explore the differences between partially threaded and fully threaded screws, their advantages, and their ideal applications.

History and Development

Screws have a long history, but the difference between partially and fully threaded screws and bolts emerged with the development of metalworking techniques. Full threading was initially developed to provide greater grip along the entire length of the screw, while partial threading was designed for specific applications where a smooth part of the shank was needed.

Technological Evolution

As manufacturing technologies have become more and more advanced, screws have become increasingly sophisticated. Modern screws can be treated with special coatings to withstand corrosion and improve their durability.

Modern Applications

Partially and fully threaded screws are used in a wide range of applications in the mechanical and construction industries.

• Partially Threaded: Partially threaded screws have a smooth, unthreaded section of the shank. This is ideal for applications where precise tightening and greater shear resistance are required. They are commonly used in structural assemblies where the unthreaded part acts as a pin, such as in connections between two moving parts. For example, in door frames, hinges and other applications where relative movement between parts is expected.
• Fully Threaded: Fully threaded screws have threads along the entire length of the shank. This type of screw offers a greater grip surface, making them ideal for applications where a strong, stable connection is required along the entire length of the screw. They are often used in general fastening applications, such as machinery assembly, steel and timber frame constructions, and in applications where a uniformly distributed load is crucial.
