What is a Keensert?

A Keensert or key locking insert is a solid bushing style insert that is threaded on both the inside and the outside and has wedges or “keys” attached at the top. These inserts are used to distribute loads and repair or strengthen threads against failures due to stripping, seizing or corrosion. They are commonly used in precision manufacturing and aerospace applications.
