The miniature M4x0.7 keylocking insert results in an increased thread strength in low strength materials such as alloys or other light materials. The external thread of this insert is M6x0.75. This insert can also be used in steel and cast iron.
Although these type of inserts are typically used in a production environment, they are also popular as a high quality thread repair solution to replace a damaged thread with the same size thread.
Go to our downloads section to get our most recent catalogues. In these catalogues you will find all the spec sheets with dimensions and drawings.
Install by screwing in the insert, rotating by hand and/or with the installation tool.
Once the insert is completely in place, tap the installation tool with the hammer so the keys are driven inside the outer thread, this accomplishes the locking of the insert in position.
