Thread repair kits must comply with standards such as ISO 9001 or GJB 119.1. Regarding materials, stainless steel kits offer strong corrosion resistance, making them suitable for chemical environments; carbon steel kits are economical and practical, but require surface treatment for rust prevention. Thread repair kits are mainly divided into wire thread inserts, self-tapping thread inserts, pin thread inserts, and tailless thread inserts. Each type is designed for different scenarios and has unique advantages and applicability.
In summary, the selection of a thread repair kit requires comprehensive consideration of materials, load frequency, and installation conditions. Correct use can extend equipment life by more than 30%, but incorrect operation may cause secondary damage; professional installation is recommended.
