308 Type Self-tapping Thread Insert

Self-tapping Insert is a type of fastener used to create or repair threads in materials such as metal, plastic, or wood. It is designed with external threads that allow it to be easily screwed into a pre-drilled hole, forming internal threads that can then accept a bolt or screw.

The 308 type refers to the specific design and dimensions of the thread insert. It typically has a cylindrical shape with external threads along its length and internal threads in the center. The external threads are designed to cut into the material as the insert is screwed in, creating a secure and durable connection.
