Turbocharger bolts: why the quality and technical characteristics of the screw connection are important for the turbine?

Due to the extreme operating conditions of the turbocharger, its components heat up to 800-1000°C and must maintain pressure in the range of 5-6 bars. Therefore, the material from which the fastening bolt is made must meet high temperature and pressure requirements to avoid their destruction. Specifically, hexagonal bolts of the hot section with a strength class of 10.9 are used to ensure maximum reliability of connections because they are designed for working conditions with high temperatures and pressure. Otherwise, lower-class screw connections will simply break, leading to the failure of the entire turbocharger and significant costs for repair.

Which fastening bolt can be considered of high quality?

There are European and international quality standards for fastening products, such as DIN and ISO, as well as GOSTs, which determine the compliance of bolts with specified properties. The Wiatreo online store offers parts for turbochargers, including bolts for the hot section. The numbers in their markings indicate the maximum force that a bolt can withstand. The marking consists of two numbers separated by a dot, where to calculate the nominal tensile strength, you need to multiply the whole number before the decimal point by one hundred Newtons per square centimetre.

We offer class 10.9 bolts made of hardened carbon steel, which have the following characteristics:

- withstand strong mechanical loads directed at stretching;

- high temperatures of the working environment do not change the material structure, making them suitable for extreme operating conditions;

- corrosion resistance.

The application of such bolts is much broader geographically than in the case of fastenings with lower strength classes, as they are also designed for harsh and moderate temperatures. Our store offers products from European factories, where each fastening bolt is galvanized using the hot method. This is a crucial requirement for their use in turbochargers as it provides additional protection against corrosion in aggressive operating environments.

What types of turbocharger bolts are available for sale?

The main criterion for choosing bolts is their intended purpose, which depends on the specific part of the turbocharger and the need for the use of appropriate types of metals for the bolts. On the Wiatreo website, all bolts are systematized and assigned to the appropriate categories of turbocharger parts, making it easy for users to determine the type of fastening they need. One of the most popular types is the class 10.9 bolt, known for its high strength and durability. It belongs to the group of bolts of the hot section, ensuring a reliable connection in high-temperature conditions. These are hexagonal models, distinguished by their ease of use and versatility of application.
