Keenserts: Inch and Mil-Spec Keylocking Inserts

What is a Keensert?

A Keensert is a small bushing style insert that is threaded both inside and out, with wedges or little keys that are attached to the top of the insert. This small piece of hardware is generally used to distribute loads and to strengthen or repair threads against failure due to stripping, seizing, or corrosion.

When is a Keensert Used?

They are used in environments that have a lot of vibration, torque, and even in high-temperature applications. They are also sometimes used in applications where a fastener has to be taken out, replaced, or it has to be reassembled.
