Description

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 are available in a wide range of inch and metric ID thread sizes. The following metric sizes are shown on this page: M5 to M12 Metric Course M8x1 to M12x1.25 Metric 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.
