Quickly repair stripped, damaged or worn out threads with a new stronger thread using keylocking inserts. Keylocking inserts are easily installed using standard drills and taps. Once the locking keys are driven down, the insert is tightly locked and will not turn. Steel inserts are C1215, parkerized. Stainless inserts are 303, passivated. Internal threads are class 2B, external threads are 2A. Inserts with internal thread size 5⁄16 or M7 and larger have four locking keys. Smaller sizes have two locking keys. Solid inserts allow you to relocate or fill in holes that are too large. All the inserts listed are in stock for same day shipment.
