NOTE: Key locking inserts such as KeenSert inserts are generally supplied as Industrial Spec. grade but can be supplied in Milspec. grade and with Certificates of Conformity on special order. Internally Locking Keyserts are also available on special order.

CAUTION

External threads on some Keensert inserts are trunctated i.e. the bottom of the external thread “V” is flattened off. For this reason ALWAYS use the below specified tapping drill size and DO NOT use standard tapping drill sizes.
