Wire thread inserts offer thread repair solutions for automotive engines

Cars are increasingly becoming people’s primary means of transportation, and one of the most common issues that arise during car usage is problems with the car engine, which is also a significant factor affecting the car’s lifespan. So why is the car engine prone to problems, and are there any methods to prevent this from happening?

During the operation of a car, the engine continuously vibrates and generates high temperatures. At this point, the threads on the engine are prone to damage. Additionally, the engine block is made of aluminum alloy material, and after multiple disassemblies, the internal threads can easily wear out and become stripped. The engine is a critical component of the car, and once the threads on the engine become loose, it becomes impossible to drive the car normally.

When the car engine is damaged, it needs to be taken to a repair shop for either thread repair or the installation of a new engine. Due to cost considerations, the majority of people choose to repair the damaged threads. In the past, repairing damaged threads involved reaming and threading the threaded hole again and then replacing it with a larger-sized bolt. This kind of operation can be considered a temporary fix, and before long, the same problem with the threads on the car engine will reoccur, leading to further thread enlargement. Over time, the entire car engine is bound to be scrapped.

In response to the issue of car engine damage, we propose a more advanced thread repair technology called “thread inserts” or “wire thread inserts.” The wire insert is made from a high-strength, high-precision, and smoothly surfaced cold-rolled rhombic stainless steel wire precisely shaped into a spiral coil. It forms concentric inner and outer threads with high precision, creating standard threads. Boerane brand stainless steel inserts have characteristics such as wear resistance, heat resistance, corrosion resistance, earthquake resistance, and anti-loosening. They can disperse stress, protect the base threads, significantly improve the performance of threaded holes, and extend the lifespan of components. Moreover, it’s not necessary to wait until the threads on the engine are damaged to use thread inserts. In fact, they can be installed on the engine before the car leaves the factory, effectively preventing the above-mentioned problems from occurring.
