True-Lock's safety retention system for critical fastener application is FAA STC PMA certified on over 1000  types of aircrafts.

Developed in 1993 for military use, the True-Lock system has expanded its uses as the only active patented locking system for nuts and bolts certified by the FAA.

As vehicle and aircraft insurance rates climb dramatically, insurance companies are continually seeking ways to reduce liabilities.

True Lock has over a decade long record of proven safety and reliability. 

For the 21st Century, the True-Lock fastening system promises a new level of safety and reliability for transportation systems.   

Currently, the United States has neither standards nor recommendations for spindle nut systems.  True-Lock, LLC is an active Committee Member of the SAE Task Force Committee currently developing the standards and testing methodology.
