Key Inserts – Heavy Duty, Stainless Steel, Internal Thread Locking (Inch)
Threaded Inserts

Internal-thread-locking version of our 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.

Heavy-duty stainless steel Key Inserts with internal thread locking are available in the following inch ID thread sizes:

1/4-20 to 3/4-10 UNC Coarse

This feature uses a modified internal thread to prevent the installed bolt or stud from rotating. This feature is useful for one-time, permanent installations.

See Technical Information at the beginning of this section for complete installation steps. Key Inserts are installed with standard drills and taps. Important: Use exactly the tap-drill size specified in the tables (slightly larger than the standard tap drill for that thread size). Locking keys are driven down into the parent material during installation, providing a positive mechanical lock against rotation. See tables below for installation tools.

303 stainless steel. Keys > 302 stainless steel. RoHS compliant.
