Description

General-purpose threaded inserts with a thick, heavy-duty thread wall, suitable for most applications. Key Inserts are ideal for thread reinforcement, especially when the mating stud or bolt will be removed frequently. They provide strong, permanent steel threads in almost 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. Heavy-duty steel Key Inserts are available in a wide range of inch and metric ID thread sizes. The following inch sizes are shown on this page: #10-24 to 1-1/2″-6 NC Coarse #10-32 to 1-1/2″-12 UNF Fine 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. See Installation Data table below for the appropriate tap-drill size.
