Product Overview
Self Tapping Inserts are threaded fastening components that combine thread cutting and reinforcement functions. During installation, they directly cut threads into the base material without pre-tapping, helping simplify the installation process and improve assembly efficiency.
Made with an integrated metal structure, these inserts create strong and stable internal threads after installation. They are suitable for various metal and non-metal materials where enhanced thread performance is required.
Compared with traditional threaded connections, Self Tapping Inserts can improve pull-out resistance and anti-loosening performance while reducing machining steps. They are widely used in repair applications, replacement operations, and high-volume assembly production.
Product Features
- No pre-tapping required, reducing installation procedures.
- Stable cutting performance and reliable thread engagement.
- Improves thread strength and reduces stripping risks.
- Allows repeated assembly and disassembly.
- Suitable for various materials and complex working environments.
Applications
Self Tapping Inserts are commonly used in new energy vehicles, battery storage systems, electrical equipment, mechanical manufacturing, automation equipment, medical devices, engineering machinery, and aerospace applications.
They are suitable for both new product assembly and damaged thread repair.
