Blind hole thread insert is a kind of fastener used to repair or enhance internal threads in blind holes (i.e., holes with one end closed). It is usually made of high-strength metal materials such as stainless steel and carbon steel, and has helical internal and external threads. The external thread is used to match with the inner surface of the blind hole to achieve fixation; the internal thread is used to match with connectors such as bolts or screws to provide reliable threaded connection.
When the original thread in the blind hole cannot be used normally due to wear, damage or processing errors, the blind hole thread insert can be embedded in the blind hole to repair the damaged thread and restore its normal connection function. For some important mechanical parts or equipment, this can avoid overall scrapping caused by thread problems and reduce maintenance costs.
The material strength of the blind hole thread insert is usually higher than that of the installed base material. Therefore, it can enhance the tensile, shear and wear resistance of the internal thread in the blind hole and improve the reliability and durability of the threaded connection. For example, in threaded holes of low-strength engineering materials such as aluminum alloy and magnesium alloy, using blind hole thread inserts can effectively improve the strength and service life of the thread.
The installation process of blind hole thread inserts is relatively simple. Generally, special installation tools can be used to screw them into blind holes. Some blind hole thread inserts also have self-tapping thread functions. During installation, there is no need to process threads in blind holes in advance, which greatly improves the installation efficiency.
Installation methods:
1.Manual installation: For small blind hole thread inserts, manual tools such as screwdrivers and wrenches can be used for installation. First, align the head of the blind hole thread insert with the blind hole, and then slowly screw it in until it is completely embedded in the blind hole. During the installation process, it is necessary to pay attention to keeping the thread insert vertical and stable to avoid tilting or offset.
2.Mechanical installation: For large or batch-installed blind hole thread inserts, mechanical tools such as riveting machines and drilling machines can be used for installation. This method can improve installation efficiency and precision, but special installation molds and equipment are required.
