Description

Internal-thread-locking version of our thinwall inserts. Thinwall Key Inserts have a smaller OD thread size than standard heavy-duty inserts, ideal for tight spaces where less pull-out strength is acceptable. 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. Thinwall stainless steel Key Inserts with internal thread locking are available in the following inch ID thread sizes: 1/4-20 to 1/2-13 UNC Coarse #10-32 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.
