Carr Lane CL-789-KS | 7/8-9 Thread x 1.25" Length Key Insert Heavy Duty

Key Inserts

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.

Application Information

Key Inserts are often used to reinforce tapped holes in aluminum tooling plates.

Repair Kits contain an installation tool and several inserts of a given size.

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. See Installation Data table below for the appropriate tap-drill size. Locking keys must be driven down into the parent Material during installation, providing a positive mechanical lock against rotation.
