Description
Key Inserts
Internal-thread-locking version of heavy-duty inserts. These general-purpose threaded inserts have a thick, heavy-duty thread wall. Key Inserts are ideal for thread reinforcement, especially when the mating stud or bolt will be removed frequently. These stainless inserts provide strong, permanent stainless steel threads in any parent Material, ferrous, non-ferrous, or non-metallic. Key Inserts are also well suited for quick repair of stripped, damaged, or worn threads. Locking keys positively prevent the insert from rotating.

Installation/Removal
Key Inserts are installed using standard drills and taps, but the required tap-drill size is slightly larger than normal for that OD thread size.
