Keylocking Threaded Inserts

Every item or MRO tool used for aviation, mechanical, and aerospace applications must be solid and reliable in high pressure and extreme situations. This is true for the newer parts and equipment manufacturing and to keep older aviation and mechanical equipment functioning. All applications require any mechanical parts to be in top functioning condition. Keylocking Threaded Inserts are useful and essential to repair stripped, impaired or worn threads that may compromise a machine and parts. When used in modern and new equipment, they provide a fresh and more robust thread part in place to prevent wear in the first place. When used in older equipment, the parts act as a new replacement thread and are often used to safely and securely repair original equipment that needs a new lease on life.

Keylocking threaded inserts are easy to install and equally simple to remove with no particular drill, tap, or pre-winders required for the job. Instead, the keys are driven into the surrounding base material thread and locked into place, making the system and equipment secure. Keylocking inserts come in various sizes and materials for a range of applications and are available in miniature, thin wall, heavy-duty, and extra-heavy-duty versions.
