key locking insert (Keenserts gen.

[amateur-1]

помогите, пожалуйста, перевести key locking insert (Keenserts) ( System and methods for power connection) спасибо.
For example, the insert may have external threads that may allow it to screw into or mate with corresponding threads on the interior of the power connection block, or any other mechanical locking device may be used. The insert may be a key locking insert (Keenserts) or a helical insert (Heli- Coil)

[Ухтыш]

Key locking inserts, more commonly known by the trademarked name Keenserts, use keys that are hammered into grooves through the threads, permanently locking the insert.
