Threaded inserts are metal cylinders with internal or external threads running down their entire length. They are inserted into holes which have been drilled into walls or other materials like metal, wood, or plastic. Their function is to enable the insertion of screws or bolts and make it a relatively straightforward process to remove them for later reuse. They are efficient fasteners and are also used to reinforce or repair existing threads. Once inserted, inserts grip firmly.
These products have several alternative names, including:
- Thread inserts
- Thread bushings
- Threaded sleeve inserts
- Insert nut fixings
- Threaded fasteners
