Part Number NAS1130-04-15 Product Information

Helical Inserts eliminate tang break-off and retrieval and are easily adjusted or removed after installation. 

Hole preparation and setup dimensions are the same for tanged Helical inserts,

Bi-Directional Design: Installs quickly and easily from either end.

Stronger Assemblies: Tapped threads are strengthened because the inherent flexibility of the insert provides a more balanced distribution of static and dynamic loads throughout the engagement length.

Eliminate Stress: Virtually no stress is induced into the parent material as no staking, swaging, or keying in place is required.

Positive Self-Locking Torque: Helical screw-lock inserts provide a positive, self-locking torque complying with the requirements of Mil-I-8846.

Minimize Space and Weight: Requires smaller boss than solid inserts; minimize total in-place cost.

Conforms to NAS1130
