    Key Inserts (Heavy Duty, Internal Thread Locking)

    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

    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.

    Internal Thread Locking

    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.

    Installation

    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. See tables below for installation tools.

    Material

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