    Threaded Repair Inserts

    Threaded inserts, also known as threaded bushings, are used to repair damaged threads and improve the thread strength of the parent material. They provide a stronger bond than nuts and tapping screws, making them the ideal choice when fastening a large or fast-moving component such as some automotive parts. Threaded inserts are usually the strongest and least time-consuming fasteners used in a manufacturing setting. They were originally designed for automation but can be manually inserted using the right tool. At Clips & Fasteners, we have a wide selection of inserts, from heavy-duty thread repair inserts to thinwall thread repair inserts. We even carry heli-coil tools for manually inserting these threaded inserts. Shop the best online selection of automotive clips and fasteners today, and get all the parts you need. We offer free shipping on orders over $99 within the continental US.
