Threaded insert

A threaded insert, also known as a threaded bushing or threaded socket, is a fastener that provides a threaded hole for screws or bolts in materials that are soft, brittle, or otherwise incapable of holding threads on their own. Threaded inserts are commonly used in applications where a strong, secure, and reliable connection is necessary, and they are particularly useful in situations where the base material may wear out over time or may not have the required strength to hold a screw.
