AT Screw / Thread Inserts & Kits

AT screw thread inserts and kits are used to repair stripped or damaged internal threads and restore a reliable fastening point (application dependent). Thread repair inserts are commonly used in maintenance and fabrication work on components made from aluminum, steel, and other metals when threads have been over-torqued, cross-threaded, or worn. Using an insert can help bring a hole back to a standard fastener size and improve durability compared to a damaged base thread.
